Re: errno=11 with EDT, ACSLS, TSM
Hi Neil, I was reading EDT literature and I found the following (from version 7.3): dismount retry_5 sleep_60 This parameter defines that in a dismount process EDT will try to dismount the tape 5 times between periods of 60 seconds... I will try it !! but I think that if we are having the same problem, it should work properly and if it does not work at first instance it should work in the following tries... Tell me your comments !!

Client Schedule Sysobj Backup Keeps Failing
Hi all , We are trying to backup DKSHH03 system state ( Windows Server 2003). However the backup seems to fail all the time. We schedule the system state backup under DKSHH03_SYSOBJ at 15:00:00 but failed. Later around 15:04:00 the backup is completed successfully but under schedule named DKSHH03_INCR. 1) Could anyone help to enlighten me why the system state backup event goes under different backup schedule name? What is the implication of such event? 2) Supposingly once a backup failed, the same backup event would NOT be re-tried again ; but why does this case happened?

Re: TSM server automation products
Background to my $.02 - in my former life as the main TSM admin in the frozen north of Michigan, our management was frankly too tight to waste money on 3rd party tools that only allowed me to do my job more effectively. Consequently, my only option was to code it myself. By the time I left, we had totally automated the daily processing of all admin functions, complete with tape checkin/out, with offsite tape slot management and other niceties. Beyond that, we had an entire menu of custom ad-hoc reports we could run at will, and a problem detection system that scanned all our potential problem areas in TSM every 10 minutes, generating emails, pages, and/or helpdesk tickets depending on how we setup our config file. Not too shabby, especially since it was all developed using Rexx running on our z/os mainframe (althought I was the TSM Admin, another group owned AIX where TSM lived, and were reluctant to give me any access beyond the bare minimum). When I moved down to sunny Tennessee, I swore I would not get locked into supporting that complex of a home-grown system ever again. I intended to use whatever was in place or the TSM Admin could convince mgmt to buy (I only deal with the Intel client side of TSM now). They bought a 3rd party tool from a vendor who shall remain nameless. When I was invited to meet with this vendor to discuss any additional reporting needs I had, I gave him printouts and source code from my most-used and I felt very needed ad-hoc report. This report presented daily session data in html and included logic to filter and/or sort the data so it could be used in a wide variety of troubleshooting scenarios. As soon as I finished my description, his reply was I'll build you a static html report, but nothing dynamic, because I'm not interested in becoming a web developer. He was not impressed with my comment that I thought he should become interested in anything his customers were interested in buying. Needless to say, I'm back to coding. Thankfully, because Rexx is so darned portable, the move from z/os to Windows has been fairly painless, so we should have what we need relatively soon. Now if I could only rake in some of the thousands of $$$ we paid for our reporting package... My biggest drawbacks to self-developed code are: 1. I'm never satisfied, so I constantly enhance it, which takes time 2. Changes to TSM, such as message formats, break my code and require time to fix I personally feel that most of the arguments about self-developed code being cursed by future generations can be eased by: 1. More documentation in the code than you think you really need 2. Putting as much of the custom stuff in config and setup files as possible, rather than being hard-coded 3.

But it does beg the question: how bad is your current situation? :) I'll allude to a bit of logical pedantry by suggesting a google of 'beg the question' :) In any case, the question is an excellent one. I mean, is it such a spaghetti that nobody, except you as the developer, can *really* get it? Isn't *that* something you could change, so that your successor can as effective as you are? The philosophical / design / practical problem here is very complex. I'd guess the average TSM clue of those admins writing their own automation code is at least a standard deviation higher than that of the larger TSM-admin population. How much of that clue may be implicit in the code, and how much must be explicit, accessible to a newcomer? Designing your code for maintainability is one thing, and we mostly think we're trying to do that. Designing your code so that a domain novice (or domain much-less-clued) can debug it is a totally different question. It may simply be an impossible task. Unfortunately, that's the problem we're talking about. I mean, issues of arrogance and modesty aside, I've been working with TSM since 1998, and with PERL since before 1992. The person hired after I get hit by a truck is in all probability going to be less experienced in both of these areas, perhaps profoundly so. But it gets worse: our automation code reflects a somewhat smeary snapshot of
Re: Policy and DRP question
TSM is not tape-oriented: it is stored-object-oriented. The copy storage pool contains an image of your primary pool(s) according to the policies for the objects stored in the primary pool. Your DR practices need to keep a copy of all data objects offsite, not just a fixed number of tapes. You're not preserving media - you're preserving data.

With the changes that I have made does this mean that we have to now keep the 10 latest tapes offsite for complete DRP?

Re: Migrating to a Library Manager
From TSMLM2, define the library as shared and all the drives. Checkin all the tapes as PRIVATE. From TSM2T, define the shared library and point your device class(es) to the shared library. Now just AUDIT LIBR shared library name CHECKL=B. This will populate the volume history on TSMLM2 with all the volume information, change the ownership to all the checked in volumes to TSM2T. Then you can do a Q LIBV on the TSMLM2 and any tape still with the ownership of TSMLM2 is probably a scratch tape. Check the volhist on TSM2T to make sure, but then just UPD LIBV shared lib name volume STATUS=SCRATCH. The big kicker seems to the the AUDIT LIBR from the library client populating the volhist on the library manager with all the known volume information. If you look at the volhistory entry for one of those tapes you'll see that the TYPE is 'REMOTE' and the LOCATION is 'library client name'.

Re: schedule start randomization
If you don't' want to make the users responsible for starting their backups, you can put a .bat file in the autologon.bat script that sleeps for 5 minutes, then does dsmc incremental. That is probably the easiest solution. The disadvantage of that , there is no TSM server schedule for it, so you won't know if they backed up or not by looking at TSM events. But, given that they are laptops, are you going to be able to have them on a schedule you can check reliably anyway? The only other thing I can think of would be to put them in POLLING mode, and have an admin script that defines a ONETIME schedule daily. Not sure if that would work or not. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Nancy Reeves Sent: Thursday, March 30, 2006 4:16 PM To: ADSM-L@VM.MARIST.EDU Subject: schedule start randomization Is there are way to have some schedules start randomly within their start window and other start immediately?

Re: Random Access Disk Pools
Rod, After spending 4 weeks using file device class disk pools, I would say use random access. Here is why: The speed of the random access disk pools is phenomenally better than the file device class - not sure why though The volumes (from the presentation I just read from the other email) are supposed to be picked based on filesystems with no volume mounted. What I found is the it selects them in collation order. This accessed the volumes on one raid group, giving the worst performance of all. After using a kludgy method to spread the data around, the performance was better, but did not approach random access Small files were a problem in some cases. Since I was collocating, if alot of small files were written to a volume (in this case, it was moving my dirmc pool), there can be alot of wasted space. Apparently, a block of 256K is written to disk no matter how much data is being written. If alot of small files are written to a volume, space can be wasted because the volume will fill before capacity is reached (we were using predefined volumes) It takes alot of time to predefine the volumes. We were finding it took about 19 hours to predefine 2TB. We were able to run 8 of those, so it ended up taking 19 hours to predefine 16TB, but that is still a long time. Some portion of space is taken up by volumes that are not yet full (with predefined volumes at least) in a file device class. This is not a worry with random access, but fragmented aggregates could be a worry. My plan is to move data off of random access volumes on the weekends to help prevent fragmentation. If you have any other questions, please let me know. --- Park, Rod [EMAIL PROTECTED] wrote: Let me ask again because I didn't get much feedback.

Since I was collocating, if alot of small files were written to a volume (in this case, it was moving my dirmc pool), there can be alot of wasted space. Apparently, a block of 256K is written to disk no matter how much data is being written. If alot of small files are written to a volume, space can be wasted because the volume will fill before capacity is reached (we were using predefined volumes) It takes alot of time to predefine the volumes. We were finding it took about 19 hours to predefine 2TB. We were able to run 8 of those, so it ended up taking 19 hours to predefine 16TB, but that is still a long time. Some portion of space is taken up by volumes that are not yet full (with predefined volumes at least) in a file device class. This is not a worry with random access, but fragmented aggregates could be a worry. My plan is to move data off of random access volumes on the weekends to help prevent fragmentation. If you have any other questions, please let me know. --- Park, Rod [EMAIL PROTECTED] wrote: Let me ask again because I didn't get much feedback.

This is usually better for the underlying disk subsystem than lots of serial writes. (at least it's been so for all my disk subsystems). It takes alot of time to predefine the volumes. We were finding it took about 19 hours to predefine 2TB. We were able to run 8 of those, so it ended up taking 19 hours to predefine 16TB, but that is still a long time. I don't get the predefined volumes bit; don't see how it could be a win. My FILE strategy has been 10-20GB files, in profusion. This keeps individual operations sane in length. My plan is to move data off of random access volumes on the weekends to help prevent fragmentation. If you're using DISK as a temporary holding pool, I'd expect fragmentation to be irrelevant. For permanent storage, however, It'd be huge. - Allen S. Rout
Re: Random Access Disk Pools
Hi, What happens in the move data of a disk storage pool volume? Are the aggregates moved instead of the files that they do contain? And thus the lost space due to the fragmentation into the aggregates is not freed up? If you're using DISK as a temporary holding pool, I'd expect fragmentation to be irrelevant. For permanent storage, however, It'd be huge. best regards, Kurt

The SHow commands are minimally documented, so what they report is not always clear. From what I've seen, the Thread table size value is the size of the table at the moment, not a fixed or maximum size. I would not infer anything further from the value. TSM is subject to OS limits, so depend upon those for max values. Richard Sims

You can't reconstruct if a random-access volume is involved. RECONStruct Specifies whether to reconstruct file aggregates during data movement. Reconstruction removes empty space that has accumulated during deletion of logical files from an aggregate. This parameter is optional. If both the source and target storage pools are sequential access, the default value is YES. If either the source or target storage pool is random access, the default is NO. Possible values are: No Specifies that reconstruction of file aggregates is not performed during data movement. Yes Specifies that reconstruction of file aggregates is performed during data movement. You can only specify this option when both the source and the target storage pools are sequential-access. - Allen S. Rout
