Eric,
Oh, THAT bug. Yes, it bit us once as well when our hp-ux system lost
its san connection to the file class luns and expiration went on its
merry way, deleting scores of volumes from the tsm db, even though
it as soon as possible...

Let me guess: FILE volumes only store a tiny bit of data before (incorrectly)

Eric,
The issues we had when we had caching turned on were:
1. Fragmentation of the the diskpool which led to a general slowdown in
processes. This can be minimized if you have a regular schedule of
flushing the cache (turn it off

Hi Jurjen!
No, that's not what I'm seeing. I have seen that TSM does not handle

Hi *SM-ers!
I'm currently struggling with the fact that I cannot run a backup stgpool
diskpool and a migrate diskpool (to empty it out for the next client backup
cycle) sequentially no more. Migration would run well into the evening and I
would like it to be ready at 18:00 hours.
I'm thinking
Eric,
Not a lot of detail in your post but I always do my backup stgpool
before I migrate so it's disk to tape instead of tape to tape. Doesn't
always happen if there is a unusually large client backup that causes
the migration to occur before the scheduled stgpool backup.
I think caching will do

Hi Eric,
You've probably thought of this yourself, but, there is no need to save up all
your backup stg operations until the end of the day. Since they are
incremental in nature, you can run the process earlier in the day with only a
short-running catchup before your migrate kicks in. Of
