I run in roll forward mode, so with a data base backup and a good recovery log, I can recover to the point of crash. So I do not do TSM mirroring of my db which is on ESS but I do mirror my (much smaller) recovery log to maximize the chances I'll be able to recover in the unlikely case that I have a unrecoverable disk problem. David Ehresman University of Louisville >>> [EMAIL PROTECTED] 09/01/05 4:06 PM >>> Hello all, I wanted to know what your thoughts are on Mirroring DB or Log volumes that resides on a storage sub system (ESS, EMC, HITACHI). They are all supposed to be redundant enough to be up 99.9999% of the time with proper server configuration (multi path to multi fibre HBA) do you guys see the need the mirror your DB and Log volumes?
