Re: Fwd: [ADSM-L] Mixing LTO2 and LTO4 drives and media in the same library
(War and Peace again - sorry): Thanks for all of your responses both on and off list. I've put some feelers out elsewhere on this too (many thanks if you're reading) and have had some interesting and contradictory responses! In summary, there do seem to be some folks out there running with exactly the proposed config below (i.e. LTO2 and LTO4 drives and media in the same logical/physical library, LTO2 used purely for offsite media generation) and, provided parameters such as MOUNTLIMIT are set carefully (as well as separate devclasses and stgpools of course), it is a happy configuration without undesired LTO2 LTO4 cross pollination. The 'Implementing IBM Tape in Unix Systems' Redbook is an excellent read and talks about this configuration in one of its examples (going against my reading of the TSM Admin Guide): As of Tivoli Storage Manager V5.3.5, LTO4 drives are supported, and any combination of LTO 2, 3, and 4 drives and media can be used in one library [...] Although LTO4 drives can read the LTO2 media (but cannot write to it), care should be taken to avoid attempted writing. Set the MOUNTLIMIT option for the LTO2 devclass to less than the sum of LTO2 and 3 drives (see the previous tip), thereby preventing the LTO2 media from being loaded in the LTO4 drives. The LTO2 media will still be available for normal use by the LTO2 [and 3] drives. ['Previous tip' - relates to different scenario but the point is still valid] Setting the MOUNTLIMIT parameter: For read or write tape mounts, Tivoli Storage Manager will select LTO3 drives for LTO3 media first. If no LTO3 devices are available, an available LTO4 drive will be selected for the LTO3 media. To prevent the case where all LTO4 drives are loaded with LTO3 media (leaving no drives available to read/write LTO4 media), set the DEVCLASS parameter MOUNTLIMIT appropriately. The above is from section 5.11.1 of the Redbook. Given the headache of repartitioning the 3584 library from its base config into two partitions without ALMS (http://www-01.ibm.com/support/docview.wss?uid=swg21145429 gives an indication of this), its inherent inflexibility plus extra work required during the migration activity itself, I'm inclined to think that the single partition library solution above is the way to go after all. I would also be able to perform a good deal of the TSM Server work (defining devclasses, stgpools etc) prior to the migration weekend, de-risking the change somewhat. That's how I'm looking at the moment - many thanks again for your thoughts. /David Mc London, UK -Original Message- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Baker, Jane Sent: 20 March 2009 08:19 To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] Fwd: [ADSM-L] Mixing LTO2 and LTO4 drives and media in the same library We have a 3584 with LTO2 LTO3 which we use via logical partitioning, it works really well so would recommend that?

I've included the text from the 5.5 TSM Admin Guide for Windows below. I interpret it to say that there is no way to keep an LTO2 scratch cartridge from landing in an LTO4 drive, and the LTO4 drive can't write to it and problems will ensue. You could indeed partition the library with ALMS. But the way I've gotten around this before with is to simply create two logical libraries in 1 physical library. (This would be especially convenient since you don't intend to keep this configuration very long.) CAVEAT: I have to say I haven't done this since TSM 5.3, so YMMV: Create a new TSM LTO4 library. Define the path for the library to point to the lbx.y.z.q device that Windows sees (this will be a control path in the library created on one of the LTO4 drives. This is usually done by the CE, but can be done easily from teh 3584 web interface.) Actually I think the path could also point to the original lba.b.c.d control point on the LTO2 drive, I don't think it matters. Define the LTO4 drives to the new LTO4 library. Your original library with the LTO2 drives will still exist just as it did before. Check in your LTO4 carts to the LTO4 library, make separate device classes and storage pools with no mixed media between them. The TSM server won't know or care that the 2 logical libraries only have 1 physical library. Again, I haven't done this with TSM 5.4 or 5.5, so test it. But it used to work.

TSM TDP Oracle - Expiration Opinions
We currently have your Oracle TDP Clients setup as a Separate node in separate a separate domain down to the storage pool hierarchy. That said we are having challenges with DBA's and their RMAN delete scripts for various reasons. According to the TDP for DB manual its recommended to have the RMAN catalog maintain retention which I would agree with but we are little success, and end up filling up virtual tape subsystems, orphaning data etc. The enough now is to have TSM maintain the RMAN retention and the DBA's would just clean their RMAN catalog with a crosscheck and delete process. What do you? Do you let RMAN maintain Retention or TSM maintain pitfalls of either?

Re: TSM TDP Oracle - Expiration Opinions
We have the same setup. TDPO backups go to separate nodes that have use their own pool. We have ongoing problems with RMAN deletes not changing the file in TSM (rman backup pieces) to inactive status, which are then removed during expiration. We don't know if it's RMAN, TDPO, or us with the problem. Our DBA's run TDPOSYNC fairly often to fix things up. Something is wrong and we just haven't had time to track it down. I have a script that queries the TSM backups table for files (rman backup pieces) that are older than our retension period. I run it once a week.

Re: VTL and Dedup ( TS7569G)
Hi, Kelly. Heh, you're right, that's a pretty funny document on the TSM side. I was of the same mind about dedup until I started getting familiar with the TS7650. The fact that it's in-line and that it does a binary diff after signature match addresses most of the concerns that I had. And I agree, it is expensive, but as a DR-tool it offers a lot of benefit. I get the heebie-jeebies thinking about not having tape involved at all in DR, so I guess I just have to figure out what requirements have to be met before I can feel good about using the eliminate your tape line. :-) I've recently found out IBM offers TS7650 appliance models that come packaged with disk and everything. Less setup, less angst, just plug it in and go. With 7TB, 18TB, and 36TB options, these appliances could be good for smaller sites.

I couldn't find a TS7569G via Google, but on the TS7650G, also a deduping VTL, after data goes through the factoring (dedup) algorithm it is run through a compression algorithm. You probably won't see much deduplication, but on the first backup you should see a decrease in size similar to the decrease you would see from the compression on a tape drive.

Pretty good detail about the product in a non-TSM environment. ftp://service.boulder.ibm.com/storage/tape/ts7650g_esg_validation.pdf And then this on in the TSM environment. I think this one might have been written by somebody somewhat less familiar with TSM than we would be.

We keep 5 days worth of TSM DB backups. $500 is real cheap in order to keep a copy of our most important DR resource on our most reliable backup medium. Everyone's different. When a shop is small enough that they only buy 20 3592 tapes for their new TSM image, it's hard to tell them that they need to set aside however many for once-a-week off-site backups of the TSM DB and however more so they can do daily TSM DB backups. Stacking DB backups for the on-site tapes would be nice.
