AND There was a discussion over the past few months about the defaults in SLES10 for disk. "by-id" is the default and it is VERY hardware dependant. i.e. it won't work in a disaster recovery site. You need to specify "by-path" in the fstab when you define you drives to linux. You can fix this after the fact, but it isn't all done with Yast at that point.
Right now, I take down the Linux image, and flashcopy it. Bring up Linux/Oracle and then ddr the flashed copy for disaster recovery. I also have Oracle take online backups to a NFS mounted directory. That is good for logical restores. However, I have yet to need to recreate or restore a table from this backup.

Once you're into Linux moving TSM there from z/OS will probably save you a bundle, even if you have to purchase new FCP based tape hardware. (Rather cheap these days. We have a smallish TS3310 library with 4x LTO4 drives that cost us about 40.000 Euro for about 160TB. We also have a more expensive TS3500 with both LTO3 and Ficon attached 3592) For full volumes backups we use VM DDR, but you could equally well use DFDSS. We backup on the VM side because we are a very restricted (in knowledge) zOS site. Besides we don't like sharing volumes over Lpars. Paranoia I guess ;-) Best regards, Pieter Harder [email protected] tel +31-73-6837133 / +31-6-47272537 Brabant Water N.V.
