amcheckdump and a tape changer
Hello! I'm using amanda 3.3 with a tape changer. It works as expected. There is only one problem with amcheckdump. On startup amcheckdumps tells me, which tape is needed and stops then, waiting for "enter". Is it possible to let amcheckdump load the correct tape? Many thanks! Matthias
tape changer failure -- amanda-3.3.3
Hello,
System OS:CentOS release 5.9 (Final)
Amanda:(brought to you by Amanda version 3.3.3)
Tape Library: SUN SL500 with 3 LT05 drives/90 slots
This setup works great!
However, if AMANDA attempts to change a tape and I have
the CAP door open, it will fail with:
These dumps were to tapes AMADSet5-30, AMADSet5-31, AMADSet5-32, AMADSet5-33.
The next 7 tapes Amanda expects to use are: 3 new tapes, AMADSet5-30,
AMADSet5-31, AMADSet5-32, AMADSet
5-33.
The next 3 new tapes already labelled are: AMADSet5-29, AMADSet5-34, AMADSet5-35
FAILURE DUMP SUMMARY:
taper: FATAL no device is available to check the datapath at
/usr/lib/perl5/site_perl/5.8.8/Amanda/Ta

node36bk.rtpnc.epa.gov /5w lev 0 FAILED [data write: Connection reset by

Is there some setting I can use to tell AMANDA to wait until the
loader is back in service?
AMANDA report and amanda.conf(partial) files are attached.
Thanks in advance...have a great day!

Tape changer question
Folks, We're running Amanda (version 2.5.1p1) on a Debian Linux system with an 8-tape AIT-2 library. We have around 314GB spread over two file systems that we are attempting to backup in one run across as many tapes as necessary. We're using gzip compression and expect it will take 5-6 tapes to complete (there's a fair amount of audio and image data that doesn't compress too well). I think we have the config files set up correctly, but it seems like no matter what we do, the run stops (after about 16 hours) and reports that it's out of tape. I don't think it has ever succeeded in spanning more than 4 tapes before giving us the error. I see nothing in the .debug output for the changer that looks different for any tapes it changes. I'm sort of at a loss for where to start looking for the problem, and what to look for. Any suggestions from the list?

Re: Tape changer question
Hi John, Do you know where in the logs to look for the problem? So far we're missing it. BTW, these tapes seem to hold just north of 42 GB each and hardware compression is off because we're using gzip. t John Hein wrote: John Hein wrote at 16:00 -0700 on Dec 13, 2008: Tim Bunnell wrote at 17:03 -0500 on Dec 13, 2008: Folks, We're running Amanda (version 2.5.1p1) on a Debian Linux system with an 8-tape AIT-2 library.

Is there any mechanism in Amanda that prevents two processes that access tape to be running at same time (dump, flush, restore, recover)? The $logdir/log file gets locked via amflock by any process that accesses the tape drive. This is much more exclusive than necessary, but it is effective.

Re: Anybody having experience with Dell LT2000 or LT4000 tape changer?
I'm also looking at buying some TL4000 units to use with Centos5 (~ RHEL5) and need to know if I can use the SAS version.

Re: Anybody having experience with Dell TL2000 or TL4000 tape changer?
I spent a bit of time searching for something specific to this and haven't had much luck. DELL doesn't cater as much to the unix/linux command line setup environment as some other vendors. They're more into the wizards and such. Note that the original message said LT2000 or LT4000 and it should have been TL. I changed that searches worked better. ;-) Anyway, a couple of things: DELL's user's manual (downloadable pdf) does say that support is available for most major platforms and lists Windows, AIX, SUN, Linux, and Netware. SAS seems to be using SCSI commands over serial connections. FC seems to do the same (use SCSI commands). MTX is a general SCSI controller for tape libraries, robots, etc. and I found references on the Amanda list saying they had successfully used MTX with FC connected libraries. So, I'm presuming MTX would also work with SAS. However (caveat), I couldn't specifically find a reference to MTX having been used with an SAS library, and the compatibility list on the MTX site doesn't seem to be exhaustive. For example, I use MTX and it doesn't list my library. So, although it would be nice to have someone pipe up and say they had this one working, I think the general answer to this type of question is that if the library works with your operating system, it will work with Amanda. DELL says it works with the operating system. To get from there to here, you need the glue. It would seem that MTX and chg-zd-mtx would be the glue. So, can anyone confirm that MTX indeed works with SAS libraries? We ought to have some general commentary on tape library support in the FAQ on the wiki. Note that: The changer interface is external to AMANDA and well-documented, so unsupported changers can be added without a lot of effort.

RE: My Monthly archive config - issue (Trying to source and use a tape changer if possible)

Cheers Chuck It should work just fine, Chuck, as long as thats a large enough tape. With hardware compression off, it will hold 12GB, and amanda, using gzip, can probably put well over 24GB on the tape. The only caveat is the tape format. Its cheap, and in DDS2's at least, I had tape trouble after 20-50 passes per tape. They claim a million passes, but the drives heads are worn out long before that in my experience. Rotary heads, are like your vcr in design, and the lifetime is measured in a small number of thousands of hours, like 3 to 5 for the life of the head. I've had maybe 1% of the problems I had with DDS2 tapes since I switched to the FILE device on a 200GB drive. For rotating heads, the head wear and damage occurs as each head tip engages the edge of the tape at the start of the track, there is tape contact and bounce there, but once 'on' the tape, there is a micron thick air cushion between the tape and the head tip. Its that crash at the entrance edge of the tape that does the damage. I've looked at tips that were actually shattered in my many years of keeping broadcast recorders going. DVC-PRO heads are 1/3rd the size of a dat head, and they can read and write 100 MB/second these days. But the electronics in those is 1000x smarter in terms of error correction too. And the error correction doesn't have to be 100%, as long as the pixal coming out somewhat resembles what went in, thats good enough, the eye is a whole lot more forgiving than data storage. Todays tape drives are still in the horse and buggy era in comparison. On Fri, 2005-09-30 at 07:39 -0400, Scott R. Burns wrote: Hi Chuck, Sorry I don't have any experience without a changer.

No, that won't work out. First of all, 40GB compressed is a purely imaginative figure that marketing pinheads have come up with in order to impress clients. It has no basis in reality; in fact they assume that your data is compressible (which might or might not be the case, but read on), and that it compresses at a 2:1 ratio (which will not be the case in real life). If you plan to use software compression via gzip, the data you feed to the tape is not compressible at all; the DDS' hardware compressor will actually expand the data before writing to tape, giving you an effective capacity of much *less* than 20GB after gzip compression, or just a little more than 20GB before gzip. Just use one *or* the other of hardware and software compression; general consensus on the list is that software compression is better if you can spare the cycles. Look in the archives for reasons if you are interested. Alex -- Alexander Jolk * BUF Compagnie * [EMAIL PROTECTED] Tel +33-1 42 68 18 28 * Fax +33-1 42 68 18 29

I'm not acquainted with the device described above, but the description doesn't mention anywhere that it's a changer. Looks more like an external tape drive. If you can connect this to your existing backup server as a *second* tape drive, then you can most likely setup Amanda to use both drives. I've read that Amanda has a changer script for this purpose, called chg-multi, but I haven't used it with real tape drives myself. --- ... Error reading FAT record: Try the SKINNY one? (Y/N)

Otherwise it cycled thru the magazine looking for the right tape, but never actually reloaded the one it found in the drive in the first place, at which point it would have found it had the right tape to start with since the reload would have rewound it. This puts a lot of war and tear on the tapes and on the changer too, probably having something to do with my own relatively poor experience with that Seagate changer. Even weirder, when it found the right label, its supposed to rewind it, and rewrite it with the new date, but because the rewind didn't work, you actually wound up with 2 label blocks written to the header of the tape, I verified that little item many times. Unforch, it appears that chg-scsi is now unmaintained as Thomas Hepper hasn't surfaced on this list in 2-3 years now. He was the last one to work on it I believe as I gave him root on my box at work so he could see if it could be improved. That was back in '99 maybe, but see the ChangeLog to be sure. If you are good at sorting spagetti code, please take a look at chg-scsi and see if its worth salvaging. I can often fix well organized code, because the organization makes it easy for this old man to visualize the codes flow. But thats spagetti, and I'm lost 40 lines into it. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Re: Conf files for tape changer scripts (or bins)
If you installed from the tarball (highly recommended) then there should be samples of these files in the src tree 'example' directory. Found it in the tar, thanks much! However, I don't suppose someone could forward me a copy of they're working chg-scsi.conf, to peruse? (I quit chg-mtx btw) The problem I'm having is if I configure it per the manual it says I don't have a tape drive, if I configure it in a way that makes sense I get a segfault. Also the manual says to enter 0 for your tape drive device in amanda.conf, does that actually work? __ Do You Yahoo!? Tired of spam? Yahoo!

Here is a chg-scsi.conf I no longer use as my last changer took a long walk off a short pier about a year back and I converted to virtual tapes on a big hard drive, and which is working much better than the tapes ever did, they were cheap DDS2's. number_configs 1 eject 0 # Tapedrives need an eject command sleep 60 # Seconds to wait until the tape gets ready cleanmax 100 # How many times could a cleaning tape get used scsitapedev /dev/sg0 # test entry per Jean-Louis request changerdev /dev/sg1 debuglevel 9:0 # # Next comes the data for drive 0 # config 0 drivenum 0 dev /dev/nst0 # the device that is used for the tapedrive 0 startuse 0 # The slots associated with the drive 0 enduse 3 # statfile /usr/local/etc/amanda/tape-slot # The file where the actual # slot is stored #cleancart 3 # the slot where the cleaningcartridge for drive 0 is # located #cleanfile /usr/local/etc/amanda/tape-clean # The file where the # cleanings are recorded usagecount /usr/local/etc/amanda/totaltime # This is the end I've no idea if seeing it will do you any good, but there it is.

Re: [OT] Tape changer recommendations
Hello! So, anyone have suggestions on external changer devices, 8 tape capacity? Any brands/model families you would particularly recommend, or would recommend we -avoid-? I vote for LTO (or LTO-2) too. In addition of the merits already listed by Alexander, it is worth mentioning that the hardware compression algorithm of LTO drives seems to be extremely efficient. I've seen as much as 440 GB of data being put on a 200 GB tape here, whereas my earlier DLT drive was rarely able to put more than 60 GB on 40 GB tape while backing up the same servers. I know that most folks recommend against using hardware compression with Amanda, but sometimes it does have its merits. As for brands or devices to avoid, I'd like to list an HP 818 DLT autoloader that we used to have. It's tape drive needed replacement after we had had it 1 year. This was done under warranty. Then the drive needed replacement again after 6 months, but the price of replacement was almost 2/3 of the price of entire autoloader. So we decided to buy an IBM 3582 LTO2 library. We've had it for a year now, and once we got it set up correctly it has given us no further problems. I must say, though, that we are not using this library with Amanda. Our Amanda setup is still using single DDS-3 drive ;-) -- Toomas Aas | [EMAIL PROTECTED] | http://www.raad.tartu.ee/~toomas/ * Work is for people who don't know how to fish.

Also, as we've been dealing exlcusively with DDS here, what are pros- and cons- of the different media formats (AIT, DLT, LTO, etc) (linkage is appreciated too, I'm sure I'm not the first to ask this)? I have two LTO-2 libraries on two sites, one Dell PowerVault 132T and one Overland Neo 2000. Both of them work fine, although in direct comparison the Overland has a much more solid feel, and is a lot faster when charging magazines. Both of these are larger libraries though, 24 slots for the Dell, 30 for the Overland. I'm generally quite happy with LTO-2 tape drives; they read and write LTO-1 tapes just fine, tape prices are dropping to around 50EUR for a 200GB (uncompressed) LTO-2 tape. When I had to choose between the different formats, I chose LTO-2 because I didn't want to be locked into one vendor. (Bad experiences with Sony's DTF which are priced outrageously expensive. This alone made me avoid AIT and DTF-2.) Sorry I can't provide any links, just my 2 cents, etc. I do completely agree with Gene, though; amanda isn't really meant to use one single large-capacity tape for several runs. If your data (currently and for some time to come) fits comfortably on smaller DDS tapes, better use one of them per day. That would also allow you to take them to a secondary storage site much more quickly, because you need not wait for the huge tape to fill up. I'd also really recommend you get a library with a barcode reader. For both my changers I've come up with a GNU barcode script to print my own labels, and it's a real treat having the changer identify my tapes with their amanda-correct label.

[OT] Tape changer recommendations

Sorry to send this out to the Amanda list, I just figure it's one of the better collectives of tape-device users to ask... It generally is, however let me remind the questioner here that the amanda design precludes useing a tape for more than one session. Too much can happen to a device in between backup sessions that would destroy any chance of the tape being in a position so that the next backup was appended to an existing one. Because of that period when the tape is not under amandas direct control, its just not worth the chance to try to append when that append may inadvertantly wipe the rest of the tape if the operator had ejected it to read the label in the meantime. So amanda is quite happy with most of the changer robots. I, if in your shoes, would go for a larger library, one that could possibly hold the whole tapecycles worth of tapes, and equip it with a drive big enough to put each nights backup on a single tape. If the library can hold all the tapes at once, and has a lockable front access door, then that tends to remove the human curiosity, janitorial tinkering and Oh, I forgot errors from your backup protocol. I suspect that far more tapes have been damaged by human handling than by the robot unless the robot is out of adjustment, said mis-adjustment often being caused by human intervention in the first place. Most of us seem to migrate to a weeklong dumpcycle, and if changer robot equipt, use a runspercycle of that same 7 days which allows amanda to spread the load, equalizing the amount of data stored each night as best she can. To that end, a disklist that is many smaller pieces is preferable to one with only 6 entries of 25GB each as amanda must then try to juggle the schedueling in 25GB pieces, not terrible effective on a 50GB drive. Having several disklist entries that are only 1 to 5% of the tape give amanda much more freedom to plan and use the medium to its best advantage. Thats my $0.02 worth. I'm a fan of the lady obviously. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

So last night when backup is running, it suppose to stored data in dailyset2, but it stored data in dailyset1 since it din't get run the day before and the file changer.stat say curslot 1 and curloaded 1. So tonight, it will store data in dailyset2, instead of dailyset3, I want to change the curslot to 2 and curloaded to 2, but the file changer.stat say DO NOT EDIT.

Re: Sg driver and tape changer.
This sounds suspiciously like either bad hardware or a bad SCSI chain. Are you sure everything is terminated properly? How's your cable length? Does it work on another machine or with a different SCSI card? What color was the goat? The tape drive was recently replaced, but I'd hate to replace it again... That driver has been undergoing some work from what I see in the kernels ChangeLog (I don't use it myself, my card is an advansys, bulletproof) and if he has the aic7xxx.old driver available, maybe he should give that one a try. My kernel is 2.4.21, and I don't recall if both drivers are still available or not. That would be my next suggestion, that he move on up to a newer kernel, thereby getting the latest code. Actually, I've narrowed it down to just having to rm/insmod the sg driver only, between every call. :P And since this is scsi we're talking about here, the goat must be pure white and a virgin.

I've got a funky polkadotted goat, and I don't think its a virgin. Must I really obtain a new one? Chuckle... You did get the point I see :) SCSI setup is very basic. One aic7000 card, one tape drive with termination. ;] If you have a voltmeter, check to see if the term power available on the scsi cable is high enough, I consider anything below 4.7 volts to be pretty borderline, and you'd be amazed to see how many card makers will use a cheap si diode for the isolation. At nominally .65 volts drop acorss the si diode, that leaves about 4.3 to 4.4 for term power. They really should be useing a schotky diode, with its .2 volts drop there but they cost more. If the drive has a jumper that will allow it to supply its own term power, enabling that will sometimes help. The bottom line is that the TTL circuitry involved has a grey area where the outputs are not guaranteed, from about .7 volts to 2.4 volts. While MOST chips will switch at about .7 to .85 volts, some logic families will use the full range of the spec. As this, for regular scsi, not lvd, is an 'open collector' circuit, this means that a logic zero is done by turning on the output stage, which will pull the data line down to maybe .05 to .1 volts, so there is an adequate 'noise margin' of about .6 volts for the logic zero state. When using resistive terms, the ideal would be to have the cable both terminated in its characteristic impedance, which for this ribbon stuff is about 120 ohms, and maintained when at rest at a voltage high enough to give a decent noise margin for the turned off state. 2.4 + .6 = 3.0 (nominally) This would all normally be accomplished by connecting a 220 ohm resistor to the 5 volt line and the data line, and a 330 ohm resistor from the data line to ground. This would establish an at rest voltage of 3.0 volts even, giving that logic one state a noise margin of about .6 volts. And the parallel combo about matches the cable impedance, all done with standard off the shelf parts values, a huge cost advantage. Unforch, there must be isolation diodes to prevent a scene where a scsi device in an external box is powered up, but the main box is not. Without the isolation diodes the external box will try to supply power via the cable to the main box. The problem gets real hairy when the isolation diodes are silicon because they'll drop the voltage at the top ot the 330 ohm resistor to about 4.4 volts, and you wind up with only 2.5 to 2.6 volts at the 220-330 junction. At that point much of the noise margin has been used up, and any residual ringing on the cable will give false signals as there is nothing there to absorb them but the terminating resistors. Things head for the toilet pretty quickly in that event. In your case, I think I might be tempted to try a different scsi card, based as much on the fact that the aic7xxx cards seem to be generating more than their fair share of problems as anything else. Humm, nother thought. These things have a bios of their own, and sometimes they can become missconfigured. Reboot, and when the cards own bios comes up, hit the ctrl+a or whatever to get into it and check its config. Maybe its own terms have become disabled or something. They should be on if it and the tape drive are the only things on the bus. Maybe we can keep from sacrificing that polky-dotted goat yet :) Russell -- Cheers, Gene AMD [EMAIL PROTECTED] 320M [EMAIL PROTECTED] 512M 99.26% setiathome rank, not too shabby for a WV hillbilly Yahoo.com attornies please note, additions to this message by Gene Heskett are:
Sg driver and tape changer.
I'm having repeated problems with my tape changer and the sg device. I'm running a Dell Powervault 120T (DLT7000 w/ 7 tape changer) on an adaptec (aic7xxx driver) card. Every time I load a tape using mtx, subsequent calls to mtx report: cannot open SCSI device '/dev/sg0' - No such device or address /dev/sg0 still exists, but I can't seem to talk to the changer anymore. I can talk to the drive itself however. The only fix I've found for this is to rmmod all the scsi drivers (st,sr_mod,sg,aic7xxx) and then insmod them again. Anyone else have similar issues? This makes using amtape conf taper very difficult. Russell

What is the best way to use a second tape changer device?
Hello List, I just got a second ADIC fastor4000 tape changer. This modle has 8 slots and 1 drive. I'm wondering what is the best way to use a second tape drive. I'm using amanda 2.4.2p2 as the server and the rpm's that came with RH7.2 for clients. I'd like to have amanda control how and when to use the drives. So that one could fail and backups would still be ok. Is this possible? or should I setup another config for the new changer? Thanks, chrisj
RE: What is the best way to use a second tape changer device?
Good question. I would like to know too. Also, I would like to know if I can put the second drive as standby as well as for recovering--- just in case an urgent recovering is demanded while regular backup is going on.

Thanks for your relpy Jon, Ok. I kinda figured I have to upgrade a stabel server someday. What feature in a current amanda build would allow me to do this?

I think with 2.4.2 the only way to use a second drive is to have separate configs for each drive. If their respective amdumps might be running simultaneously, you have to make sure the same client host does not appear in both configs.

Re: Solaris 8 Overland Tape changer config
Nigel, I believe the only problem with labeling the cleaning tape is that you can't readilly check the tape label. Cleaning tapes are really physical device that emulate the SW device /dev/null, useful for some applications. That is what they do afterall, absorbe all the left over bits on the drive heads.

Re: Solaris 8 Overland Tape changer config
I may have been missing something in my config - something like an environmental variable, but I found that I wasn't able to run chg-zd-mtx successfully unless I was in the directory with the data information. That is, I configured amanda such that the chg-zd-mtx.* files where in the amanda config directory (/usr/local/etc/amanda/config) but the script was in the default /usr/local/libexec directory. In my case it was a matter of not locating the config files and I see from your execution line that you where probably in .../libexec.

If not, you needn't use any changer entries Overland XB with a DLT700 drive. dlt /dev/rmt/1n (I've had the tape respond to this, so i know its right) Well, at least it works. Does rmt/0 also work (say with tar or dd)? changer /dev/sq/c3t610 (created using Veritas stuff, I can't vouch for it) Guessing here, sq == sequential, which is one of the sgen driver types. An c3tXXX sounds like c == controller 3, t == target XXX, but certainly not target 610 as the target generally means scsi id, like 0-15. Are you sure that is not c3t6d0 (target 6 device, i.e. lun, 0). But the location is not what I've seen. What is /dev/sq/c3t610, a device, a symlink (to what?)? Is there a /dev/scsi/sequential/* with maybe the same information? How about /dev/changer/? Thought 3. you have changerfile set to chg-multi. that would suggest your tpchanger should also be chg-multi Done that, now playing with the chg-multi.conf file I should have written they need to match, not that you should choose chg-multi. multi is meant for multiple drives, not for a changer. Thought 4. for my Solaris system and drive chg-mtx worked fine. others have used chg-zd-mtx (note you will have to obtain and install mtx). Still others have configured the sgen (generic scsi?) driver and used chg-scsi, or the chg-mtx's I explored mtx and sgen, and was unable to get either to create a device for me. Not surprising that mtx didn't create a device. It doesn't. It operates on a changer device. Maybe your /dev/sq/* device. Thought 5. /dev/rmt/1n ? Do you have another tape drive at 0? /dev/rmt/1n responds as the tape drive, but I don't have anything I can get to respond at /dev/rmt/0n, even though all the files are there in /dev/rmt/ Is this something I should investigate, or can I ignore them? Do you only have one tape drive/changer? Is other software going to be screwed up in some important way if the device names change? If only 1 and no other software problems, you could get a complete device reconfiguation and likely move the drive to drive 0, removing all else. The stuff in /dev/rmt are just symlinks to stuff in /devices. A device reconfiguration at reboot would entail touch /reconfigure and reboot or at boot time, at the ok prompt, do a b -r (boot -r). Sometimes old stuff keeps reappearing. If so, rm all the /devices/.../*st* (st == scsi tape, or is it sequential tape) devices that are pointed to from /dev/rmt and all the /dev/rmt links. Then either the reconfiguration reboot or read up on devfsadm to recreate the devices without reboot. The deprecated, obscelescent command tapes would also do the same device recreation I think. Thought 6. the device /dev/rmt/1n is choosing the default density and/or compression for your tape drive. If that is what you want, fine, otherwise check into 1ln, 1mn, ... Ah, wondered what they all were! I'll investigate, thanks for the heads up prtconf -v will give lots of output including some stuff about st devices.

RE: Tape Changer Question
If I understand the working of Amanda correctly, Amanda will postpone some full dumps if the estimate of all the filesystems are larger than one tape even though the setup is to use two tape drives. Amanda will write to one tape until the full and write to the second tape. Correct me if I'm wrong. Can Amanda breaks up the backup job so it can spread the filesystems that are backup to multiple tapes? For example, amanda will backup those filesystems that fits on one tape and backup the rest of the filesystems to the other tape which will reduce the postpone of some full backups.

RE: tape changer
Here's a few things to try: 1. make the tape changer work separately from any AMANDA components. You might need zd-mtx or similar. (I use the ch driver and utilities from http://www.strusel007.de/linux/changer.html.) I'm guessing you're using some flavor of linux based on the device name /dev/sg0. 2. Make AMANDA work with the tape drive in the changer using the chg-manual changer. This means that before every backup, you will have to use the control commands from step 1 to load the right tape, but your backups will be working. 3. try the AMANDA changer script that matches the changer-driver you've selected. If you're using the one I linked to above, search the list archives for my chg-userland perl script that glues it to AMANDA, or let me know if you can't find it, and I'll re-post it. -Original Message- From: Martin A.

MRU tape changer software from Compaq
Ref. an article from far, far away (Date: 2000/04/20): (article quoted below) I am trying to use the changer option with the MRU software from Compaq. This software has an entry point via the `robot` command and has syntax such these examples: robot load slot 0 drive 0 robot unload drive 0 slot 0 Does anyone have any more information about configuring Amanda for use with an MRU changer utility? Is it true that the changerfile and changerdev variables are unnecessary? (as shown below) I have a notion that simply providing a symlink to the robot utility in /Amanda_Installation_Location/libexec is overly simplistic and will probably not work as the interface Amanda expects may not be consistent with the MRU command interface. Tips...? Please send them to me via private e-mail. (if you prefer) or send to the list if appropriate... I really could use some help... Config files, etc... I will post a summary of the entire installation process, to help others find answers in the future... Thanx!

Variables to control tape changer
Hello, I have just acquirred a Quantum/ATL L500 library. -yay- I believe I have it functioning correctly, but there sure appears to be some arcane information regarding the changerfile configuration for chg-scsi. Here are my thougts/questions: 1) why would I want to use scsitapedev instead of dev in my changer config file? 2) What is the purpose of the sleep variable? Is it the time amanda will wait from when the changer returns to when the tape can be used? I set mine to 140 seconds as the documentation for my tape drive shows an average of 133 seconds to load a blank tape. 3) it is not clear if I can tell amanda to tell the tape changer a barcode value to load instead of searching the slots... = Now here are the specifics My amanda server is a dual pIII redhat 7.0 linux box, running amanda-2.4.3b3. this machine has the following tape hardware attached: /dev/nst0: sony dds3 4mm drive only (currently used to do backups) /dev/nst1: quantum/atl dlt8000 (tape on library) /dev/sg1: Tape changer mechanism. #dev= scsitapedev=/dev/nst1 amcheck-server: slot n: tape_rdlabel: tape open: 0: no such file or directory my chg-scsi file showed: warning open of 0: failed #dev= scsitapedev=/dev/sg0 I can't recall, but it didn't work dev=/dev/nst1 #scsitapedev= This is where I got the thing working correctly. perhaps /dev/sg0 would have worked, if I had unloaded kernel module st, and reloaded sg. I didn't want to do that though since I am running backups on /dev/nst0. What do you all think?

tape changer chg-scsi problem
Hi, I've being using amanda for a couple of years. Recently I upgrade amanda from 2.4.1 to 2.4.2p2. I also upgrade the clients to 2.4.2p2. Now I have problems with chg-scsi. I red once that the new version of amanda's chg-scsi changer supports Exabyte's X220 library. I configured amanda.conf with chg-scsi: tpchanger /usr/lib/amanda/chg-scsi tapedev 0 rawtapedev /dev/null # the raw device to be used (ftape only) changerfile /etc/amanda/Daily/chg-scsi.conf changerdev /dev/sg0 In chg-scsi.conf I set eject 0 (to use eject), changer to sg0, tape to nst0, cleancart to 1, rotate tapes between 10 and 19. Here is my chg-scsi.conf: number_configs 1 eject 2 # Tapedrives need an eject command sleep 25 # Seconds to wait until the tape gets ready changerdev /dev/sg0 # Next comes the data for drive 0 config 0 # Daily drivenum0 dev /dev/nst0 # the device that is used for the tapedrive 0 scsitapedev /dev/sg0 tapestatus /home/amanda/Daily/tapestatus labelfile /home/amanda/Daily/labelfile startuse10 enduse 19 statfile/home/amanda/Daily/statfile cleancart 1 cleanfile /home/amanda/Daily/tape-clean usagecount /home/amanda/Daily/totaltime 'chg-scsi -status' seems to recognize that the library has 21 elements: DecodeModeSense : Element Address Assignment Page Medium Transport Element Address 86 Number of Medium Transport Elements 1 First Storage Element Address 0 Number of Storage Elements 21 First Import/Export Element Address 0 Number of ImportExport Elements0 First Data Transfer Element Address 82 Number of Data Transfer Elements 1 but 'amtape config update' doesn't unload a tape to the slot from where it was previously loaded but unload it always to slot 1 (that is declared as cleancart and shouldn't be used).

OpenBSD, AMANDA 2.4.2p2 and a HP 24x6 tape changer...
I have a HP SureStore DDS-3 24x6 tape changer. This changer worked as expected with AMANDA under Linux but I have huge problems getting it to work with chg-scsi. I can navigate the changer with chio and talk to the tape with mt. Is there someone using chg-scsi with a HP tape changer under a OpenBSD or another BSD? If so, could you please send me your config file? I have problems figureing out which devices I should use. Under Linux I used: changerdev /dev/sg0 dev /dev/nst0 scsitapedev/dev/sg1 Sven

Elaboration on tape changer behavior
Can those with experience with changers elucidate some details for me? What is the AMANDA/amtape policy when rolling over from the last tape to the first tape in my Backup Set? My config specifies the following: dumpcycle 2 weeks runspercycle 5 tapecycle 10 tapes In my changer the slot numbering is zero-based. So I have tapes in slots 0 thru 9. Since I do not have a working changer script between amtape and my tape library manager sw layer, I am manually running robot load commands (etc...). I have three general questions: 1) Will amtape manage the rollover from tape slot 9 to slot 0, and, in general, do the right thing? Is there any manual intervention on tape slot rollover? For example. must the admin tell AMANDA that it is OK to write over a tape (tape 00)? 2) Is there any important information omitted from the document, AMANDA Tape Changer Support? Can it generally be trusted to specify the correct interfaces? I have found that some of the tape changer implementations in the AMANDA distribution do not correctly follow the API specifications in that document. 3) Do people with single tape robots use multiple tape magazines; swapping them out after one tapecycle... as in Magazine A then Magazine B, then back to A? Or do some people just keep running tapes through the magazine, ad infinitum? Or do most people leave the same magazine installed until the tapes wear out? I presume this last question (3) is largely dependent upon one's goals... So if anybody cares to elaborate on changer methodologies used to achieve particular goals, then I would be grateful. Other will surely benefit as this is not an area that is discussed in much depth. Thanks for your time... J

Other will surely benefit as this is not an area that is discussed in much depth. You need at least a couple more tapes, since with your current setup if you ever have a tape error or an extra-large backup and need to amflush, it would need to overwrite an active tape. The other answer is, as you suspect, 'it depends'. If you do offsite rotations of your tapes, it is easier to do it a magazine at a time. If your robot holds several magazines you might want to cycle through one set for onsite backups and have a different Amanda config do offsite backups on another magazine that you replace each time. Even if you don't do offsite, swapping tapes a magazine at a time is much safer than swapping tapes. The tapes will last longer in a magazine (less likely to get banged around, dropped, dirtied, etc.), and you have fewer chances to get the tapes out of order. Magazines also stack better and are easier to store. I'm assuming your magazines can be swapped easily, if not then it might not be as favorable to swap them. Unfortunately, some vendors see magazines as an income opportunity and charge way too much for them. Also, do you need archival backups (to retrieve a file that was only around last June), or only the ability to restore what was there in the last few days or weeks. With your config, if a backup fails for some reason, and a file you need wasn't on the system in the last week, you may not have it (as you are just now about to overwrite your first tape, and whatever fulls it contains cannot be recreated with the following 4 incrementals so all you can recover from those filesytems of that week is the changed files. If the full of those filesystems can't be read from the one this week (due to a bad tape or whatever) you are SOL. I would recommend making sure you always have at least two full backups of everything, even if there are a couple of errors during your cycle.
