Curious media selection for catalog
7504 on Solaris10 master with remote windows 2008r2 media server, also 7504, LTO4, robotics.
I run a catalog backup to my windows server: I have a pool for this purpose and I have 5 tapes in the pool. The image last for 7 days so I can just cycle thro the tapes day1=tape1, day2=tape2 etc. The catalog is about 75Gb, so with one tape capable of holding 1.2Tb lets say, you would expect this to run smoothly so long as one remembered to put a catlog tape in the robot. Even if a tape was left in there for a few days , it would get appended to, theres plenty capacity on a single media.This has been the way for years....
However this week four days in a row its changed: the catalog tape has not been selected, its just picked one from scratch. The "time assigned" is blank.
Mounts is 120-130 give or take, and isnt limited, no expiraton date,....its all normal/sensible.
So how can I figure out why its now doing this?
I presume the media selection logic is the same for catalog tapes, but I'm struggling to believe it is.
Despite all the tools to examine data tapes, catalog tapes seem to have been left out.
Thanks in advance,Jim
