Hi, Steve. If restoring a file takes multiple small volumes in one
pool, but only one large volume in another pool, TSM will choose the
pool with the fewest volumes/mounts required, even if the smaller
volumes are significantly faster. This causes some problems with
restores choosing real tape over small file or VTL volumes. Well, I say
that as if it's fact, but while I haven't seen that documented anywhere,
that's what I've observed. I've also received hearsay confirmation from
various IBM sources that it is this way. YMMV :-) I think this might
have been addressed with the libtype=vtl, and I'd like to see
confirmation on that, but that wouldn't help you much with file class
volumes.
I recommend you check your actlog for the sessions in question to see if
they've been getting tape mounts during restores. If so, try setting
your copypool unavailable to see if that alleviates the problem.
update stgpool copypool access=unavailable
The other question is, why would the copypool volumes still be
available? Is this only happening in the window between "backup
stgpool" and "move drmedia"?

Thanks, Steve.
I checked, and the node does have backdel=y. it almost acts like it is going
to the copypool rather than the diskpool for the meta data, but that makes no
sense.

Hi Steve.
Check to make sure that the node has backdel=yes specified. I had one SQL
server that was on a legal hold for 4 years and the restore screen took that
long to come up because of the large number of objects. If backdel is set to
no, the logs won't be getting deleted and that may account for the large number
of objects you are seeing.

Our DBA's are complaining that when they have to use the TDP gui to restore older
databases by selecting "active/inactive", it sometimes takes 20+ minutes for
the list of databases to refresh.
My first suspicion was that the meta data had somehow gotten off to tape, but I
have confirmed the primary data is all on disk (ST03_DISK_P04), only copypool
(ST03_TAPE_C04) is on tape.
Any ideas what would cause this behavior?
