To confirm device names, you should work with one online drive at a time, and cycle through the storage agent device names until a successful backup can be run. The server cannot validate PATH information that is provided on the server for use by the storage agent. Failures can occur if incorrect device information is provided in the DEFINE PATH command. so it should be enough to try backup if fails change /dev/rmt/(1-6)m value in DEVICE field, restart STA and try backup again, right ? but it does not work for me !!! --- thanks in advance the desperate one
Re: Reclaimation of virtual volumes
Curt, Please issue the following two commands and compare the two numbers. They must be 2 or more for reclamation to work. 1. At remote server: Q devc remote-device-class f=d * Note down the value for mount Limit 2. At local server: Q node remote-server t=s f=d ** Note down value for Maximum Mount Points Allowed Update these two numbers to 2 or more and reclamation should work successfully.

Re: Advice needed for EMC CX500 setup
Hi Brion, I see that no one else has responded . . . . . let me stir up the waters and see what shakes loose . . . You don't inidicate the the number of nodes, db objects (files), backup rate (gb/day), etc, etc that you expect. This is key. You indicate a db of 70 gb with a full sized log - this means to me that you expect heavy db activity. For the tsm db, or for any other db for that matter, the question is how many iops do you need? The 133gb fc disk drive can probably give you around 120+ iops. I'm afraid that a 3 spindle raid 5 probably is not enough iops to run tsm instance with the activity you might have. Before my time on the storage team, Emc sold a disk subsystem to us for one of our TSM servers. It was a Clariion with all big drives. Like most disk purchases, it was configured on capacity, not i/o load. There was no way to split the drives between db/log and staging pools and have enough disk space for staging pools, or, enough spindles for db/log. The only way to make it work was to spread db/log/pools across all the spindles. NOT good . . . . actually, it worked quite well for the first year.

Re: New Volumes
Look at your 3584 setup or operator guide. On a 3583, there is a command sequence that you enter on the library front panel that tells the library whether to record 6-digit or 8-digit barcodes.

Splitting files across tapes

Re: InsertSlashHack error, missing dir delimiter
Hi, Matthew - Another of those cases where the client programming fails to explain problems that it finds and could interpret, resulting in a lot of wasted customer time. I believe that this condition can occur where there is a conflict in file system object type. For example, the object was originally backed up and stored in TSM storage as a directory, but in the current backup the TSM client finds that object to be a file. The CLI output is not helpful in this case, except to verify existence, as the CLI remains exasperatingly primitive, even in TSM 5, failing to provide any way to report the object type. You could instead use the GUI, drilling down to that point in the filespace, to identify the object type; or do a more arduous Select in the BACKUPS table for TYPE. (In worse cases, there may be non-visible binary bytes in the name which throw things off, put there by the file's creator, or by file system corruption.) You'll have to poke around to ascertain what the story is, and possibly compensate by object renaming in the client file system.

Richard (Aaron too), Many thanks for taking some of your time trying to help me ! Yes, you're absolutely right, my mail was lacking some important information, but I did not really knew where to begin ... To answer some of your questions : - number of nodes : approx 200, equally split in Windows and AIX environments. Some of them also hosting Informix and DB2 databases. - backups/day : approx 400 GB AIX/Win data, and 500 to 750 GB informix/db2. No archiving (except db2 logical logs), no hsm. - db actual size : 30GB, 80% used; expected 50% increase within one year (proportional to the expected increase of nodes). Number of objects (from expiration process) : 610. Our actual performance for expiration is approx 160 obj/hr, not much, but due to time constraints space reclamation is running parallely and slows it. I would expect getting the same performance, or better ! - log size : 13 GB for security as I'm using rollforward mode - expected iops : well, no idea at all. Some formula to calculate this ?

reclamation tape predicting
Oh mighty gurus. We have had to relocate some of our tapes to an overflow location because of our silo capacity. I basically mark them as unavailable and shelf. When reclamation starts, I redefine some of the tapes to readw and wait to see if TSM calls for them. I then have to physically insert them into the silo for each request. Is there anyway to query TSM to generate a list of tapes that it will require for reclamation? That way, I can redefine just those tapes and load them all at once into the library. Thanks! DaveZ
Re: reclamation tape predicting
Same situation here, but we have 120 tapes in our 60 slot 3583. When space reclamation runs, it fails everyday, so they take a list of tapes TSM asked for, get them off the shelf, and check them all in. I think this was asked a very long time ago, and there was no real answer - you'll have to run it to acquire a list of required volumes. ..unless there IS in fact a way of determining these volumes.. It would be great to hear it.

Re: Splitting files across tapes
Hi Richard, Thanks for responding; maybe this will give you something to amuse your brain over morning coffee. The reason for the question, mgmt here is considering going to all-disk backup (for onsite). So our sequential volumes will be disk instead of tape. We occasionally have issues with mis-classified data ending up on a tape, and the tape has to be pulled and destroyed. No big deal with a tape. Big deal when the volume is a 1 TB raid array! So the question comes, what is the likelihood that we would contaminate TWO 1 TB raid arrays with a split file? I think for sequential volumes, TSM doesn't know that the volume is full, until it tries to write to it. If there isn't space for the next block, then it mounts a scratch and rewrites the block to a new tape, yes? So can I assume that the file would have to be larger than an aggregate (what is that, MOVESIZETHRESH?) in order to end up split across 2 tapes? Thanks for lending brain power!

Re: reclamation tape predicting
Another approach is not to use reclamation, to avoid the unpredictability... I will assume that it is a subset of primary storage tapes which are ejected from the library and stored somewhere outside it. Leave your outside-library tapes unavailable for reclamation. When housekeeping time arrives, have a dsmadmc-driven programette query for external primary tapes which have enough space worth reclaiming, then call for their reinsertion; then Checkin and perform 'MOVe Data ... RECONStruct=Yes' on each volume in turn. You will likely have to operate on just a few tapes at a time due to your library cell constraints. Checkout as needed. This is a pain, but operating a library in other than enterprise mode makes for such irregularities. Your management may want to assess the cost of implementing such a scheme against the cost of additional library space. Richard Sims
Re: InsertSlashHack error, missing dir delimiter
The InsertSlashHack message is less than informative, but was intended
more for development use in diagnosing problems than end-user use. That is
essentially the case for any message that does not have a message number.
It is desirable that such messages be re-evaluated for their usefulness,
rewritten, or at least preceded with ANSE, but that is another issue
to be dealt with for another day.
Sometimes, including the case of ANS1304W, the root cause if often
non-deterministic from the client's perspective. At any rate, there are
times when it is appropriate to contact IBM technical support for further
assistance, and this might be one of those times. In fact, if you review
the current user response section for message ANS1304W (which was
updated in version 5.3), you will see that it includes the following text:
* If the reason this message occurred can not be determined and the

Hi, Matthew -
Another of those cases where the client programming fails to explain
problems that it finds and could interpret, resulting in a lot of
wasted customer time.
I believe that this condition can occur where there is a conflict in
file system object type. For example, the object was originally
backed up and stored in TSM storage as a directory, but in the
current backup the TSM client finds that object to be a file. The CLI
output is not helpful in this case, except to verify existence, as
the CLI remains exasperatingly primitive, even in TSM 5, failing to
provide any way to report the object type. You could instead use the
GUI, drilling down to that point in the filespace, to identify the
object type; or do a more arduous Select in the BACKUPS table for
TYPE. (In worse cases, there may be non-visible binary bytes in the
name which throw things off, put there by the file's creator, or by
file system corruption.)
You'll have to poke around to ascertain what the story is, and
possibly compensate by object renaming in the client file system.

Hi Matthew, Personally, I would like to see that InsertSlashHack error message either rewritten to indicate that this is an internal error that needs to be taken up with IBM technical support, or taken out of the error log altogether. Thus far you've done a good job of trying to track down the cause. I would recommend that you obtain a SERVICE trace that captures the problem, and contact IBM technical support for further assistance. To get the trace, add the following to the dsm.opt file: TRACEFLAGS SERVICE TRACEFILE some_trace_file_name (you can pick your own trace file name) Then reproduce the problem. When contacting support, provide the complete command line output, error log, and trace file, along with the other information that you have gathered on the symptoms of the problem.

Re: Splitting files across tapes
On Jun 7, 2005, at 10:06 AM, Prather, Wanda wrote: Hi Richard, Thanks for responding; maybe this will give you something to amuse your brain over morning coffee. The reason for the question, mgmt here is considering going to all- disk backup (for onsite). So our sequential volumes will be disk instead of tape. We occasionally have issues with mis-classified data ending up on a tape, and the tape has to be pulled and destroyed. No big deal with a tape. Big deal when the volume is a 1 TB raid array! I would recommend against destroying such RAID arrays - sounds expensive. :-)) So the question comes, what is the likelihood that we would contaminate TWO 1 TB raid arrays with a split file? I think for sequential volumes, TSM doesn't know that the volume is full, until it tries to write to it. If there isn't space for the next block, then it mounts a scratch and rewrites the block to a new tape, yes? So can I assume that the file would have to be larger than an aggregate (what is that, MOVESIZETHRESH?) in order to end up split across 2 tapes? A magic word in your scenario is sequential. This means you will be using File type devclass. TSM 5.3 allows you to make the volume size whatever you want, up to the limits of the file system. A judicious choice will make for a size which affords nice capacity while not being ponderous when you have to deal with a stray. And I should think that you could deal with the stray by doing an Expire or Delete Backup command from the client, perhaps followed by a MOVe Data ... RECONStruct=Yes on the containing server volume if there needs to be assured erasure of the goner. With this, may it be the case that concerns over volumes and spanning are unwarranted? File type devclass volumes may incite more predictive processing in TSM, given that there is the advantage of known size, whereas the actual length of a tape is not known. That is, TSM will probably know there is insufficient space for the next Aggregate, or clump of a file whose size is larger than an Aggregate, so as to go to a new volume. (Now, I don't know for certain, but have to suspect that the File volume's size is uniquely tracked in the db rather than simply taken from the devclass spec, given that the devclass MAXCAPacity can be updated at will. Thus, the size of volumes over time should be deterministic.) If there's definitive doc about all this, I have not yet encountered it. Someone out there may have more info. Thanks for lending brain power! If I were really smart I'd be charging for exposition of what I know, rather than working for a living. :-) Richard Sims
Re: reclamation tape predicting
Few years back I was in a similar suitation. I had 300 online tapes but only 60 slots. I first of all made sure that I only would perform restores ! I left all the online tapes that couldn't be housed in the library as available close by. They were mostly full and readonly. When I needed to do reclamation I used to set mountwait to 1 minute, so that after one minute if tape was available reclamtation would end. UPDATE DEVCLASS device-class_name MOUNTWAIT=1 UPDATE STG COPYTAPEPOOL RECLAIM=60 Ran reclamtion for a while, say 30 mins, and ended up with a list of tapes required, from the activity log. UPDATE STG COPYTAPEPOOL RECLAIM=100 I then checked in the tapes made them available and repeated reclamation. I similarly ran large restores, with restores always remembering to update mountwait to 60 or even longer, after the first trial run .

Re: Splitting files across tapes
Are you talking about a 1TB VOLUME, or several smaller volumes (say 10GB) on a 1TB array? H. Milton Johnson -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Prather, Wanda Sent: Tuesday, June 07, 2005 9:07 AM To: ADSM-L@VM.MARIST.EDU Subject: Re: Splitting files across tapes Hi Richard, Thanks for responding; maybe this will give you something to amuse your brain over morning coffee. The reason for the question, mgmt here is considering going to all-disk backup (for onsite). So our sequential volumes will be disk instead of tape. We occasionally have issues with mis-classified data ending up on a tape, and the tape has to be pulled and destroyed. No big deal with a tape. Big deal when the volume is a 1 TB raid array! So the question comes, what is the likelihood that we would contaminate TWO 1 TB raid arrays with a split file? I think for sequential volumes, TSM doesn't know that the volume is full, until it tries to write to it. If there isn't space for the next block, then it mounts a scratch and rewrites the block to a new tape, yes? So can I assume that the file would have to be larger than an aggregate (what is that, MOVESIZETHRESH?) in order to end up split across 2 tapes? Thanks for lending brain power!

This results in the subsequent data being written in a spanned Segment on a new volume.

Re: reclamation tape predicting
When housekeeping time arrives, have a dsmadmc-driven programette query for external primary tapes which have enough space worth reclaiming, then call for their reinsertion; then Checkin and perform 'MOVe Data ... RECONStruct=Yes' on each volume in turn. You will likely have to operate on just a few tapes at a time due to your library cell constraints. Checkout as needed. The problem is messier than the above proposal indicates. A tape that is a candidate for reclamation may start with a file continued from another volume, or end with a file that is continued on another volume. If either or both of these things happens, the 'move data' for the reclamation candidate will attempt to mount the tape or tapes containing the other parts of the spanned files.
Control of data flow in collocation group environment
Can I have the control of the data flow in the collocation group set up environment? For example, I like to have collocation group A moving their data through migration to storage pool A. If the answer is yes, where is the control? I do not find in the def collocgroup or def stg help menu. Thanks for the response. Frank Tsao [EMAIL PROTECTED] PAX 25803, 626-302-5803 FAX 626-302-7131
Problem with Web client on linux
Hi all, I installed TSM 5.2 on linux advanced 2.1. I added passwordaccess generate option in dsm.sys, started dsmcad. When I access via Web client, I always see dsmcad service was defunct . I also setup TSM 5.2 on other Linux and it operate well. What is the problem ? Thank a lot, Nghiatd,
