Re: TSM Administrative Tasks
We also spend some time making sure our storage pools are balanced to improve performance in the case of a large scale restore, but also to improve backup performance. Another task is identifying retired nodes and file systems to reduce the data stored. Our biggest challenge in that area is me are not informed when a server has a drive removed, so we have to watch for file systems that have not backed up in a while.

Re: TSM Administrative Tasks
Analyse collocation status of onsite and offsite media in anticipation of their need. If you have nodes with data scattered on too many offsite tapes, it will greatly impact your ability to recover your environment in a timely manner. Review, test, and document your recovery plan.

Re: TSM Administrative Tasks
Curtis, I'm not sure if these fall into managing a system category, but they are things that I have dealt with on a periodic basis. Customer service - Gary calls and leaves a voice message asking for a restore of the file veryimportant.txt in his home directory because he accidently deleted it. A quick search of the files backed up do not show that file and a voice mail to Gary asks him to confirm the file name. He responds that the file may have been deleted some time ago - not sure when, but he is sure it was there last month and it may be called something else - If we could just restore everything, that would be fine. Working with Management - Can you explain to management in 5 minutes the different data retention settings and how they interact with each other? - Can you explain why and how TSM may maintain two copies of data in primary and copy pools and why you shouldn't just eject your primary pool tapes to save library space rather than purchasing additional library space? - Demonstrate to management why the incremental-forever methodology of TSM is superior to the Daily/Weekly/Monthly methodology of other data recovery products. Cheers, Neil Strand Storage Engineer - Legg Mason Baltimore, MD. (410) 580-7491 Whatever you can do or believe you can, begin it. Boldness has genius, power and magic. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Curtis Preston Sent: Thursday, August 21, 2008 6:14 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] TSM Administrative Tasks It's taking me forever, but I'm still developing the outline for my latest book.
