Re: Reducing fragmentation in disk storage pools of type disk.
That seems unnecessary to me, just like running defrag on a filesystem doesn't help it if you delete all the files on it first. My question is: Once the volumes in the disk storage pool are empty, would it further reduce any chance for fragmentation in the disk storage pool to remove and re-define the disk storage pool volumes? -Oorspronkelijk bericht- Van: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] Namens Robert Clark Verzonden: vrijdag 7 mei 2010 22:11 Aan: ADSM-L@VM.MARIST.EDU Onderwerp: [ADSM-L] Reducing fragmentation in disk storage pools of type disk. (TSM Server 5.5.3.0 on Linux 2.6.9-89.0.11.ELsmp x86_64) I'm working with some disk storage pools (type disk) that traditionally have not been migrated to the point of being empty. There have been times recently when we've struggled to get the disk storage pool migrated quickly enough to keep it from filling almost enntirely. We suspect this is leading to the log getting pinned. We've adjusted the hi and lo migration thresholds, and have made some plumbing improvements to speed up migration. As a precaution, we're also migrating the disk storage pool until it is empty. My question is: Once the volumes in the disk storage pool are empty, would it further reduce any chance for fragmentation in the disk storage pool to remove and re-define the disk storage pool volumes?

Anyone using DPA?
I know this has been asked before (and not answered), but is there anyone out there using DPA from EMC? Has anyone given it a close look? Fred Johanson TSM Administrator University of Chicago 773-702-8464
Re: Anyone using DPA?
We are using EBA/DPA We had a custom report running on EBA that didn't work on DPA, so we are trying to get that worked out before we upgrade. (DPA is being run in a test environment) We've tested Aptare and Servergraph as well, and EMC's product fits our particular environment better than the others. The main thing we do that the others have trouble with is that we have multiple nodes per server and the others didn't handle this in the way that I wanted it. They just handle them differently, not better or worse. You should evaluate this for yourself. My main problem with DPA is that there doesn't seem to be any advanced documentation or training if you wanted to do anything above basic reporting customization. The Professional Services is the only way to do any advanced customization. You could muddle around and figure out quite a bit by yourself, but I wish there was some good documentation. If you do purchase this, make sure and include a few days of PS and have a list of the custom reports you want.

Re: Anyone using DPA?
Hi, We are implementing DPA at the moment and I really have noticed difference between IBM and EMC documentation. I thought that EMC provides documents which are even close to those I have seen about TSM... I was so wrong. Our main difficultie is that you can't use collector in clustered environment but you can use this proxy to collect some things from TSM. But when you are using this proxy you don't get all that information which you can have with collector. Like networker, you just can't configure it like you can configure TSM and TSM-OR.

Snapshot Backup Best Practices
First, sorry if I've posted this in the wrong forum ... I'm new to this and didn't see a general questions forum. I'd like to know if it's a bad practice to create the volume shadow copies of the volume you're backing up on the same volume that you are backing up? For example, suppose I'm backing up D: using VSS and I'm writing the shadow copies to D: ... is that bad practice. Thanks.

Re: Anyone using DPA?
Fred, I would agree with Shawn. I have worked with DPA, and other EMC products, and also with IBM products for many years. EMC often makes good products, but assumes that you don't need good documentation. They will have all the manual titles you could ask for; Quick Start Guide, Administrators Guide, Programmers Reference, etc. but the manuals will have nothing but superficial overviews in them. Nothing like what you would find in the equivalent manuals for an IBM product. The IBM Manuals may take a long time to find your way through, but at least your odds are much better of finding what you are looking for. On the other hand, EMC support will give you extra help when you ask for it. IBM Support is usually mainly about defect support. They aren't there to help you configure the product; if it is working as designed then you are on your own. EMC support, however, has often answered how-to questions about configuration issues. So perhaps they are trying to make up for the lack of good manuals. Best Regards, John D.

Re: Snapshot Backup Best Practices
You need to find another forum, this mailing list is about TSM. The forum you think you see is a front to this mailing list.
