Re: Any market for used tape media?
De-gaussing is the only practical way to erase a significant quantity of tapes, and degaussing will render a number of modern tape formats useless forever. One of them is LTO. Not sure about 3x9x. (It's because, in addition to removing the data, degaussing also removes the servo tracks on the tape, and the drive won't recognize the tape.) My opinion: It's not worth the risk. --- W.

Re: TSM For ERP with DB2 config
Are you seeing anything in the server activity log? One issue that I ran into was that the logs and database should be stored in different storage pools when using the include logs option. Otherwise the backup can preempt itself doing a log retrieval...there's a technote that describes the problem. If you run the backup without the include logs, does it complete? -Lloyd On Fri, 14 Dec 2007 09:48:43 +0530 Sachin V Chaudhari1 [EMAIL PROTECTED] wrote thusly: HI, Thx for the reply.

Re: sql tdp hang issue
Did you examine the TSM Server activity log closely? Was there a problem where a tape did not get mounted in time? How many stripes are you using for the backup? If you are using multiple stripes and one of those stripes is waiting for the TSM server to mount a tape, it can cause this. I have seen this when the TSM Server does not have enough available tapes mounted to satisfy the DP/SQL request. The Waiting on TSM server indicates that DP/SQL is waiting for some event on the TSM Server to occur before it can continue sending any more data. Is it possible that some TSM Server event pre-empted the DP/SQL backup and took one of the tapes that was needed to satisfy a multiple stripe DP/SQL backup request? You should start on the TSM Server... in the activity log to find out what it thinks happened.

Re: Any market for used tape media?
Curtis, 3590 tapes are where IBM servo tracks were first invented (unless it was 3570, I may be mistaken). 3592 and LTO are follow-on technologies built from those first ones. De-guassing shouldn't be the only way this could be done. It ought to be possible to write multiple passes of bit-patterns to a tape, making the old data unreadable. If you look at the tapeutil utility IBM provides with the atape drivers, it includes an erase function. It would be easy to write a program to mount the tapes in a drive one at a time to erase them. But I could not find any documentation online that really explained what the erase function was doing, and if it was thorough enough to withstand HIPAA requirements. Best Regards, John D.

Re: Strange difference between Primary and Copypool
I'm working without the benefit of a set of doc PDFs at the moment, but I have a fairly specific recollection that when Group Collocation was introduced in 5.3, the default behavior for collocation on an new storage group changed. I could be wrong, but if Eric has any new storage pools, they might default to collocation by group -- and as I recall, nodes that aren't defined to be in a specific group are treated as if they're in they're own group. The consequence is that for new storage pools, the default starts to act like collocation by node unless you specifically put nodes into collocation groups. I hope I'm wrong, because this seemed really, really weird when I was studying collocation by group, and like I said, I'm working from memory at the moment, but *if* Eric has new (defined under 5.3 or later) storage pools, he might be using collocation without realizing it. I really, really hope the family memory problems aren't kicking in today :) (If I'm all wrong about this, please be gentle.)

Was there a problem where a tape did not get mounted in time? How many stripes are you using for the backup? If you are using multiple stripes and one of those stripes is waiting for the TSM server to mount a tape, it can cause this. I have seen this when the TSM Server does not have enough available tapes mounted to satisfy the DP/SQL request. The Waiting on TSM server indicates that DP/SQL is waiting for some event on the TSM Server to occur before it can continue sending any more data. Is it possible that some TSM Server event pre-empted the DP/SQL backup and took one of the tapes that was needed to satisfy a multiple stripe DP/SQL backup request? You should start on the TSM Server... in the activity log to find out what it thinks happened.

Re: Data Domain Question
Charles, The one thing to be aware of with any dedupe offering is that when using a dedupe system with TSM, you will get significantly smaller dedupe ratios than those customers using it with Grandfather-father-son-based software (e.g. NBU, NW, CV) due to the progressive incremental nature of TSM. Where a lot of the dedupe comes from is reducing the redundancy caused by creating repeated full backups. Since TSM doesn't create repeated full backups on filesystems, they don't get as much dedupe. Depending on the product, I've seen everything from 3:1 to 10:1. If it's 3:1, that's a joke, as you can get almost the same with just hardware compression, which costs far less. Also, all dedupe products are not created the same, and this is especially true for TSM. So if you hear FUD about particularly bad dedupe rates from someone, don't assume that all vendors would get that dedupe ratio, or even that you would get that dedupe ratio with that vendor. Make sure to ask your vendor about their knowledge of TSM configs with their product. Here are a few resources that may help in your search. First, here is a link to the discussion on this list that someone eluded to. (44 posts on deduplication with TSM): http://tinyurl.com/3bwc9a BackupCentral.com has a Wiki that contains a directory of all disk targets for backups: http://tinyurl.com/2dtvh2 This is the first entry in a multi-part series on deduplication. Each blog entry contains a link to the next entry in the series: http://www.backupcentral.com/content/view/58/47/ This is a podcast I did on dedupe: http://searchstorage.bitpipe.com/data/document.do?res_id=1188480907_629 Hope this helps! --- W.

Re: Data Domain Question
Thanks, Bill! That's great stuff. It's good to see that they see dedupe as a key feature. As he says, it won't benefit TSM customers as much as others, but it will still benefit them. It's interesting to see that they're going to do server-side dedupe first. They'll already have that with the TSM VTL when they release their dedupe version, and that's likely to be released first. I guess the idea is to give you dedupe without having to buy a VTL. From a purely educational perspective, there's a lot of good info in there just about dedupe, but the preso does describe dedupe as if it's synonymous with hash-based dedupe. That is actually only one three methods of deduping.
