TSM Performance 5.5 vs 6.2
I need to show management that simply upgrading TSM from 5.5 to 6.2 will not cause a degradation in performance. I know a lot of upgrades are done by moving to new hardware. We don't have that luxury. We are currently running on AIX 6.1 on p520 server. I've already upped memory to 32gb. Anyone have any experience to share?

Re: TSM Recovery log is pinning since upgrade to 5.5.5.0 code
Did this issue ever get resolved? I've noticed the same thing for my 5.5.0 server and have been trying to isolate the issue, but to no avail.

In addition, we have noted the many PMRs coming into the IBM support queue, and many of these PMRs are now on my queue. Andy will be assisting me along with other support people as needed. As part of this analysis we will be doing, we have a new questionnaire (titled Items to Gather for a PMR with Log Pinning Condition for TSM V5) that customers will be filling out that ask several questions regarding your environment. We understand that this involves extra work to gather this information, but there can be many different areas that can cause log pinning conditions, so this information is needed. In addition, there will be a script provided (named serverperf5a.pl) that will help us gather additional data. Both of these will be provided to you by support. When these PMRs are now opened, please make sure that level 1 support adds the keyword LOGPIN55 to the PMR. This will allow Andy and I to quickly find all the PMRs being worked for this issue. Eric, your PMR is now one that I have on my queue (or I will shortly today). We will be contacting you to work the PMR.

In this mode the recovery log only contains uncommited transactions. Don't you agree that in this case, the log should NEVER reach 90%? It should not even reach something like 40%! I don't want to have to implement extra monitoring to keep TSM from crashing. It should just work. Like it did when we were running 5.3...

We are already running 5.5.5.2 and the log is still filling up, even after switching from rollforward to normal mode. Management currently is questioning whether TSM is the right product for the future. Although I'm a big fan of TSM for 15 years, I'm really in doubt too...

Several others on this list reported this behavior and (as far as I know) three other users opened a PMR too. I hope they have more luck, because I'm stuck. Level 2 keeps on saying that the log keeps on growing because of slow running client sessions. Indeed I see slow running client sessions, but they are slowed down by the fact that TSM is delaying all transactions because the log is used for more that 80% during a large part of the backup window!

Here is a small follow up on my PMR about the recovery log utilization. I'm at TSM level 2, still trying to convince them that there is something broken in the TSM server code. To convince them, I have changed the logmode to normal on one of my servers. I created a graph (through TSMManager) which shows the recovery log utilization during last night's client backup window and is doesn't differ much from the night before, with logmode rollforward. When running in normal mode, TSM should only use the recovery log for uncommitted transactions, so utilization should be very low. My log is 12 Gb and the backuptrigger value (75%) was still hit twice! This clearly shows that there is something wrong with TSM, let's hope I can convince Level 2 too, so my case gets forwarded to the lab. I'll keep you guys posted!

De-dup ratio's
I'm curious what others are seeing for de-dup ratios for various methods. We're using IBM's ProtecTier for our TSM (5.5) primary pools and only see about a 4 to 1 ratio. This is less than half of what IBM was projecting for us. We have roughly 400 clients (mostly Windows servers) totalling about 135TB of data. Biggest individual uses are Exchange and SQL Dumps. Just wondering what others might be getting for other appliances or with TSM v6?

Turning Encryption Off/On
We currently encrypt all our offsite tapes. Mgmt wants to me create a single unencrypted archive tape to be stored offsite long term for litigation reasons. My question is: If I turn off encryption long enough to get some data written to this one tape, then turn encryption back on, could I then continue to write uncrypted data to this one tape while all other tapes would be encrypted? IBM is being non-committal saying we should really use new device class, but I'd then have to move one tape drive over to new class each time I want to write unencrypted.

Re: Turning Encryption Off/On
Using hardware encryption, managed by TSM. Are you saying I can have two device classes sharing the same devices? For some reason, I was always under the impression that you couldn't. But after scanning the help, I don't know where I came up with that notion. That would definitely make things simple for me. Thanks. -Original Message- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Wanda Prather Sent: Tuesday, January 12, 2010 10:20 AM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] Turning Encryption Off/On Is your encryption application-managed (controlled by TSM) or library-managed (controlled by EKM/TKLM)? If application managed, IBM is correct, you just need a different devclass that specifies drive encryption OFF, pointing to the same library, and a new storage pool that specifies the non-encrypted devclass. . I've got 4 LTO drives, onsite pool is NOT encrypted (long story there), COPY pool IS encrypted. No biggie.

Used 3494 / 3590 equip
Just wondering if anyone knows what the market might be for a 3-frame 3494 with 8 3590-H1A drives. Also, is there market for about 1800 used 3590E cartridges? We just finished migrating off and my boss just wants to trash the whole thing. I'd be curious to know just how much money they're throwing away.
