Re: Seeking wisdom on dedupe..filepool file size client compression and reclaims
Good Morning We have been in the planning stages of moving our production backup server to our non prod site and setting up cross site vaulting. The more I think about it, the more it makes sense to build a new server and point the clients to the server running TSM6.*. Our prod server is currently running 5.5.1 and the clients are also updated to this level across AIX, Linux, Windows and TDP for RMAN. Can someone point me to the documentation for supported clients etc as in the short term I was hoping to build the server as rev6 and leave the clients for the short term? Any gotchas running TSM6* on AIX would be appreciated. Look forward to your response Warm Regards -Original Message- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Allen S.

I understand the case you're making, and I agree that the size of your files has an impact. I'm suggesting that the impact isn't huge, and that it evens out in a reasonably short timeframe. Eventually, whatever the volume size, you wind up with a library full of volumes more or less randomly distributed between 0% and 50% reclaimable. If you're keeping up with reclamation, that means you're _in_ a steady state, so you're _doing_ the same amount of work per unit time. So when I say "To a first approximation, it's irrelevant", focus on the "First appoximation" bit; Yes, there are variations here, but don't sweat them too much. It's certainly possible to back yourself into corners with very large or very small volumes. - Allen S.

The tape drive wasn't the library control path. Since we have two control paths, and the ALT path turned on in the AIX driver, I would hope that wouldn't be a problem anyway. But our Atape drivers are about a year old. It would not hurt to update them. Also, or IBM3584 firmware level is 7360, and 7363 is available.

One is a IBM3584 tape library with 24 LTO4 drives. The second is a virtual tape library, an EMC EDL configured as a IBM3584 with 128 LTO1 tape drives. The library master has 9 other TSM instances and 4 Lan-free clients that are library clients, and appeal to it for tape mounts. Most of the time this works just fine. All the TSM instances are running TSM 5.4.3.0. A few weeks ago we upgraded them from 5.4.2.0 in order to pick up a patch to provide the LIBSHRTIMEOUT parameter. This may not have anything to do with our problem, but it IS a recent change. The problem comes when we have any problem with the real IBM3584 tape library. Two weeks ago a tape got stuck in the gripper. Last week the gripper itself actually broke, so no tapes could get mounted. Last night it was a single tape drive that got an error and went Polling. For some reason, in each one of these cases, after an hour or two all tape mounts start hanging, even those belonging to the virtual tape library. When we would do a 'q mount' they all showed up in Reserved status. So before long all backups going to the virtual tape library ground to a halt. Can any of you see a reason why the TSM library master should get into such a problem? Shouldn't all tape mounts be asynchronous? It seems like to me a single tape drive getting into problems should not keep all other mounts from proceeding. And it doesn't happen instantly. It seems to happen gradually. I probably should also mention that this is a fairly busy environment during the night. It isn't unusual for us to have over 100 virtual tape mounts simultaneously. That is the reason we needed the LIBSHRTIMEOUT parameter (mentioned above). Before we had that, we sometimes would get timeouts that caused tape mount failures, because the TSM library master's queue of tape mounts polls would get overrun. Since we put on that patch, and added 'LIBSHRTIMEOUT 60' to the options file, that problem has gone away. But now this problem seems to have taken it's place. Best Regards, John D.

Cross Site Vaulting
Good Morning I am looking for direction on which way to go. We are in the process of setting up cross site vaulting and not 100% sure on how to incorporate both nodes and libraries to share the libraries. I assume the most efficient way would be to have a library manager instance that controls both libraries from our remote site? If we were to loose the library manager we would then configure the libraries to each LPAR to manage their own libraries? Also consider library partitioning. Our implementation has a restricted budget where as we are attempting to set this up with existing infrastructure besides a couple of new 595 LPARS. An overview of what we have is x2 3584's one with an expansion and the other as standalone. A CWDM link with a 8gb trunked link over 15klm's and two 595 LPARS 1 cpu and 8gb mem. Two HBA's for disk and four HBA's for tape drives. Prod data will go across the wire to our non prod site which will have our prod backup server and vice versa. We are limited to 4 drive slots in the smaller frame library and have 4 LTO3 drives and 9 LTO2 drives in total to manage the data. We are planning on using two LTO3 and two LTO2 drives in the smaller library which will hold prod primary storage pool data and the rest in the non prod library. As the restriction of the size of the prod library we are only planning on copying prod data across sites and copying non prod data within the non prod library. Currently hold approximately 200TB's backed up data across two servers. The current two instances are 5.5.1 and all associated clients. Can someone point me to a doco or have a similar experience? I have been trawling through redbooks and google is my friend.

Re: Time to reclaim LTO tapes
We have reclamation set up to 70 using our LTO3 drives which only hold Oracle data and usually consists of largeish files. They usually reclaim faster due to higher transfer rates etc then LTO2 and LTO. It is one of those how long is a piece of string questions depends on the variables including the server. We also run LTO4 on another site. As the price of LTO4 comes down I would consider LTO4's over LTO3. One to two occasionally three hours reclamation is complete.

Re: TSM performance very poor, Recovery log is being pinned
Evening I have been watching these comments with interest as we are currently in the process of building a new TSM server.

Look forward to your response Regards -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Craig Ross Sent: Tuesday, 31 July 2007 7:09 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] TSM performance very poor, Recovery log is being pinned Thanks guys. All this advise is much appreciated. For the record my TSM servers seems to have returned to more normal routines. However the log is still being pinned and log fills up to about 12% then flushes, not ideal but acceptable. I am starting to wonder if my install has always had the log pinning issue I just did not know!! I will keep close eye on it. But I feel ultimately I will install 2nd TSM server and migrate some Node's to new server. I did find a bad configured batch of new SAN storage which is promoting the slowdown/pinning. I have stopped using this particular disk and performance has returned to norm. However this was not obvious before because server was busy, I could not pin point easy as once stopping the trouble spot TSM was not jumping into life straight away it had too process the back log of requests And of course I could not afford to leave server on go slow for long periods. As result I am currently in review of all new Storage installed to ensure its running optimally. I will propose to management to install new fast disk for log and DB as the pinning still issue. However this is where the debate continues, I have experimented with DB volumes log volumes and storage volumes with FS and raw volumes and have not seen any performance difference (on the same disks) ie have deleted volumes created RAW and FS and seen no difference. I have read material on both sides of this story and no seems more convincing than the other except I remember reading somewhere the only eyebrow raiser was with RAW on solaris you can have issues, I cannot remember exact issue but potential is there. So after testing both formats finding no difference. I use FS for everything, if this is an indisputable mistake please let me know. Also we have 10 10 Gb volumes for DB should I create more smaller ones? While I am here though I have another cloudy area, since upgrading server from 5.1 to 5.3 installing IBM tape device driver and adding 4 LTO3 drives I swear my 6 old LTO 1 drives are running slower than previous is there some gotchas when installing IBM Tape to get drives running well! 6 LTO 1 drives are SCSI attached and 4 new LTO 3 are fibre.

TDP Exchange
Evening Currently looking at upgrading one of our TSM servers! There are even requests to replace it with another vendors software as there has not been a lot of satisfaction from the current infrastructure. We are running TSM 5.2 Level 6.0. We are looking at upgrading the Server to 5.4 and 5.3.4 clients. The server predominately backs up windows clients and a handful of Linux and Aix clients. Data consists of a group drive and a exchange server.. The exchange data is currently dumped into a directory locally on the exchange server using NT backup, then TSM backs this up. Why it is done like this I believe dates back to cost restraints. The biggest issue I am aware of why the admins want to dump the software is to restore ACL's and individual mail boxes. So I believe the answer would be TDP for MS Exchange? Is anyone currently successfully achieving what I am looking at?

Re: Tape drive zones for FC drives - best practices
I agree with the best practice though it generally depends on your budget infrastructure. Eg 20 HBA's in a P595 Series would pretty much be a draw. If you want to be pedantic you should have separate HBA's for host as well if running LAN free. My experience to date if you have separate HBA's for your disk generally two for dual paths. And for example 5 separate HBA's for tape drives you will still get the desired throughput etc. The only time I have seen multiple failures because of one device is with the 3584 as the picker is controlled through the first drive. My two cents worth, good luck.

We have never experienced a device taking out all devices in a zone - because we went with the best practice of one adapter <-> one target per zone from the beginning. For clarity and sanity sake, use aliases for each device host side and target side and a naming convention like: 'host-fcs2' or 'switch2-rmt12' for the aliases, create the zones using the alias names and roll up everything into a 'config' that you enable (load into flash memory on the switch). Thus 6 months down the line when an adapter or device fails and is replaced and you are scratching your head at the schema you drew for yourself on a scrap of A4 ... you just login to the switch(es) and do: admin> alishow# list your device aliases admin> aliadd # add new WWN admin> aliremove# remove the old WWN admin> cfgshow # show the new alias in the defined config admin> cfgsave # save the config to internal flash admin> cfgenable# enable the changed config admin> cfgactvshow # sanity check HTH Ian Smith Oxford University Computing Services England.

Re: TSM inventory of empty slots becomes inconsistent wi th IBM3584 li brary.
Hi What is the library you are using? 3583? Look at drivers. Show slots will give you a good idea where your tapes are. This cmd has to be run when there are no sessions mounts proc etc for it to work. Remove any tapes except for the tapes the vendor recommend eg IBM use IBM. I have had a PMR open on one of our libraries for months which has slowly got better though every now and then it will give the exact same problem, with slots. Easiest way to get around it is to power cycle remove paths and the add, add the carts and it runs ok again. Add the scratch first. Obviously we have scripted all this. The library in question is a 3583 scsi library which we are looking at replacing anyway. Or maybe you just have to run a audit.

Richard, Thanks for your reply. I had already read the Technotes you referred to. I try to hit the knowledgebase before I go to the list; of course, I am certainly capable of overlooking something. The element numbers being misassigned would cause mounts to be done incorrectly; where TSM tells the library to mount a tape in drive element 257, expecting that to match up to /dev/rmt3, but instead /dev/rmt3 is really drive element 258. If that were my mistake, I would be getting ANR8300E errors during a mount, but instead it is always a dismount, where TSM finds the slot full trying to put the tape back where it got it from. And as I mentioned, I can sometimes go for days, with 50-100 mounts for each tape drive, before the problem suddenly appears. So a basic configuration mistake like would show up right away, not after days. The ANR8469E can certainly be a stuck tape, or other hardware problems caused by a drive, but if you look at the ANR8300E that comes just before it, it tells us that the destination slot is full during the dismount. So I think the ANR8469E is in response to that. I should clarify that, although I am doing library sharing, there is only one library master. All mounts and dismounts are done by him; the others just make the request. So the errors I am seeing all appear in the library master's activity log. Best Regards, John D.

John - The joy of inherited environments, where you have no solid information on how things were configured by your predecessors... In my experience, an ANR8469E unload failure is always due to a tape drive hardware problem (possibly a sensor or motor problem). Check your records or logs to gauge whether one or two drives are troublemakers and need work. A tape stuck in a drive tends to stay in the drive, where it subsequently being put away in a strange place *might* be due to human actions. Sometimes, a seeming unload failure can be a timing problem in the drive microcode, where not enough time is being allowed for the operation. See IBM Technotes (1143428, 1212674) on the possible causes of ANR8356E. An insidious problem is where the barcode is inconsistent with the magnetic labeling of the volume. Element number inconsistencies are another gem. Beyond that, I would activate TapeAlert and review AIX Error Log entries. You also say that you are doing library sharing, so I would review the logs of both sharers and see if both are experiencing the same kind of problems, which may illuminate configuration or software issues. what I can think of, Richard Sims Bunnings Legal Disclaimer: 1) This email is confidential and may contain legally privileged information.

TSM Data Refresh
Afternoon all We are currently contemplating the best way forward in a data refresh test at a remote site onto a node that is running the same version of AIX 5.3.* and TSM 5.2.6 Our three scenarios we are contemplating are a backup set, image backup and group backup. The pros and cons of both the backup set can be created from the backup server and image from the client. As the site on which we would like to perform the refresh does not have a concurrent TSM server so we would have to do a db restore so the image or the backup set could be read. There also only a stand alone a single drive to restore the data from. Any thoughts would be greatly appreciated.
