Hi Richard!
This file was part of a filespace migration for one of my clients (migration
to Veritas filesystem on a Sun client).
My biggest concern is that the client did report 0 errors during the initial
backup! The file was backed up by the client, send to the server and written
to tape with no errors according to TSM. When we tried to restore the file
in question on the client, it resulted in a "not available on server"
message.
I think that during that attempt the file was marked damaged in TSM and thus
TSM skips the file during storage pool backup operation.
The file in question was a database that was obsolete after the migration.
(Am I lucky!)
I now have the nasty feeling that a successful backup does not guarantee a
successful restore...
Kindest regards,
Eric van Loon

Eric - This may be one of those interpretation and semantics issues.
The ANR1257W message description says that the file involved is one which
was
*previously* marked Damaged. Your most recent storage pool backup thus did
not
discover the problem, but merely responded to the flagging to skip the file
and
go to completion. It that sense, it was an orderly and successful storage
pool
backup. I would expect that the backup which discovered the problem did not
complete successfully - we hope. It would be worth it to all of us if you
could go back in Activity Logs and see what happened at discovery time.
Also, run a query and see if that instance of the file is already in the
backup storage pool - which would be a good thing, allowing you to recover
it
to the primary pool. A RESTORE STGpool Preview=Yes would probably tell you
if this were so.
