tuning mount retension
I'm trying to tune our mount retension settings on our device classes. Currently, we have it set to 3 min for our 3590 drives. I'm not finding much info on how to tell if our 3 min period is too long or too short. 1st try . . . . I sorted the mount messages (anr8337i)in a actlog listing of 24 hours by volume/date/time and looked for multiple mounts of the same volume that were real close together in time and on the same drive. I found just a couple. 2nd try . . . I counted the number of the following messages in a actlog listing for 24 hours: anr8337i - mounted vol msgs = 415 anr8325i - dismounting with expired mount retension = 230 anr8468i - dismounted vol msgs = 415 This might indicate we had 185 instances of mount retension being useful. But . . . I'm not sure of is whether a mount satisfied by a already mounted tape even has a mount msg in the log I'm also not sure whether a tape always waits for the mount retension period to be dismounted, or, whether it can be immediately dismounted if there are pending mount requests for other volumes. I looked in the manuals and online but didn't find much that helped. Any thoughts on how to tune mount retension are appreciated Rick - The information contained in this message is intended only for the personal and confidential use of the recipient(s) named above.

FW: TSM 5.3, AES-128 encryption and API/TDP backups
An update, as I've sorted it for now - it is kinda buried away, but searching on 'transparent encryption' in the TSM 5.3 API manual reaps dividends: http://publib.boulder.ibm.com/infocenter/tivihelp/index.jsp?topic=/com.i bm.itsmc.doc/ansa77.htm I've got this working for TDPSQL on Win32 now (although the only simple way I could think of verifying it was working was to enable tracing on traceflags encrypt and encryptdetail and checking for AES128 comms), and will take a look at the Solaris TDPO as soon as I can. The storage of the encryption key within the TSM server database (i.e. not on the client itself as with the 'traditional' TSM encryption) is interesting, and does make me think about the possibility of managing offsite TSM DB backups separately (i.e. different physical location) from our offsite data tapes... At least, that's what I think security might pick up on when we run this past them...

I believed this was possible in 5.3, but I'm not having many (or in fact any) hits in the online docs (or IBM.com or ADSM.org) trying to find out how to get this working, only how to get the BA client to encrypt via encryptiontype, include.encrypt etc. As ever, any help or pointers gratefully received.

Currently, we have it set to 3 min for our 3590 drives. I'm not finding much info on how to tell if our 3 min period is too long or too short. You're probably not going to see behavior problems because of bad mount retention settings except in relatively extreme cases. But for your questions: I'm not sure of is whether a mount satisfied by a already mounted tape even has a mount msg in the log I don't think so. I'm also not sure whether a tape always waits for the mount retension period to be dismounted, or, whether it can be immediately dismounted if there are pending mount requests for other volumes. Absolutely, yes. In general, you'd want to increase your mount retention if you find that you're dismounting and re-mounting the same volume many times in succession, for no good reason. Good reasons basically come down to needing that drive mount point for some other tape. Dismounting because you need the mountpoint is pretty much reasonable. :) You'd want to decrease your mount retention if you find all of: + You usually have the wrong thing mounted + You usually have had it sitting idle for a long time (locally defined) + You are sensitive to the additional mount delay occasioned by a dismount Or, (as in my case) you're polling your 3494 for tape occupancy on a regular basis, and you want to have things dismounted if they're not immediately in use, otherwise your numbers go awry. - Allen S. Rout
Mount retention, the extreme case.
I did find a case in which I had difficulty getting a TSM library client to do e.g. reclamation when I had mount retention set wrong: If you've got a library client which you've set to have access to two drives, and mount retention set to some normal value on the library manager (say, 5 minutes) you can enter a state in which a reclamation process does: - Mount source volume - Mount destination volume [ copy data, finish with dest. ] - Make mount request for new volume - Get refused: too many mount points - Process fails, TSM admin gets irritated. What I eventually did was set the library manager to have zero mount retention, which fixed this. My drives stay busy, with a line queueing up, most of the day. So I didn't mind the more-or-less immediate dismount. - Allen S. Rout

Solaris TSM Server 5.2.4.0 and the Query Libvolume command
Can someone confirm this before I report it to IBM? Seems to be a bug in this release of TSM (5.2.4.0) with the command, query libvol, see below. A query volume wn3006 shows the tape WN3006 as being used by the ARCHTAPE storage pool. A query libvolume wn3006 shows that it is not in the library. Yet, when I executed an audit volume, the tape mounted and read without issue. If I execute a query libvolume qualstar WN3006, the tape shows up in the library. Note the difference is explicitly stating the library name, qualstar. The help file indicates that the default for the library name is all libraries. This matches how all TSM Servers worked at earlier levels. Note also that if one executes query libvolume (without any parameters) the tape in question DOES shows up. tsm: WINDSOR_TSMq v wn3006 Volume Name Storage Device Estimated Pct Volume Pool Name Class Name Capacity Util Status (MB) --- -- - - WN3006 ARCHTAPEAIT3 118,795.0 100.0 Filling tsm: WINDSOR_TSMq libv wn3006 ANR2034E QUERY LIBVOLUME: No match found using this criteria.

Re: Solaris TSM Server 5.2.4.0 and the Query Libvolume command
I do not think the code should ever have worked in the manner you described, since the library name and volume name are positional parameters. Thus QUERY LIBVOLUME WN3006 implies that WN3006 is the library name, and should always have indicated no match found. I am not aware of it ever working otherwise. I'd say that the doc could stand some clarification, to indicate that if the volume name is specified, then library name is also required.

Tape Drive Confusion
Configuration: TSM V 5.2 OS = Aix 5.1 3584 Library (latest Firmware) 2 Fibre Switches (4 LTO GEN 1 Drives Each) 8 LTO GEN 1 Drives 2 Fibre Cards Switch 1 (Drives 1234) Switch 2 (Drives 5678) I just recently Added 2 new LTO Tape Drives to my 3584 Library. In doing this I had to add a new switch and decided to split the load on the switches to help throughput. In doing this I had to delay my backup stgpool jobs so that is currently running. In order to catch up on time I thought why not use the new drives. I Issued the command backup stg (Onsite Tape Pool) (Offsite Tape Pool) maxpr=3. Now the backup is running really slow if the process has tapes mounted on switch 1 and 2. If they are on the same switch they run fine. Am I missing some type of configuration here or something? Please assist as I was sold this as being a faster solution and then sold it to my Sup's as a faster solution. If more info is needed please let me know.

Re: TSM causing client disk contention
Paul, Yes, We've noticed this. Our solutions: * Start backups when users have supposedly gone home. * Don't do 'hot backups'. Have the application export its own backup to a flat file (preferably on another file system), then backup up the flat file. * Just backup what you MUST daily, then do another schedule to pick up the 'other stuff' on weekends. (Like, pick up user home directories and data directories daily, backup the OS and software weekly, since I changes little. This keeps down the time to query the database about whether or not something has been backed up. * Use journaling locally (we have issues with it, but when it works it helps) These hints don't make all problems disappear, but they help. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Paul Zarnowski Sent: Monday, April 25, 2005 3:37 PM To: ADSM-L@VM.MARIST.EDU Subject: TSM causing client disk contention We have a couple of clients here (Sun, Windows) who have noticed dramatic slowdowns on their application servers when TSM incremental backups run.
