So, we should just ignore the error?

Steve,

The reason that you are seeing this error is that Oracle/Rman first tries
to delete the backuppiece that it is about to create on the TSM Server. In
this way Oracle/Rman ensures that only one copy of the backuppiece exists
on the Backup Media so Rman tries to delete the backuppiece in case it
already exists. The Rman specifications state that only one copy of a
backuppiece will exist at one time on Media Manager (DP for Oracle).

Unfortunately, Oracle/Rman also specifies that the delete routine act as
single and seperate operation, so when Oracle tries to delete a
backuppiece that does not exist, that is an error and DP for Oracle
returns that error. There is no way for DP for Oracle to determine if the
deletion is a true delete of a backuppiece or if Oracle is checking for
backuppiece existence prior to backup.

Hope this helps clear things up.

Thanks for that bit of information... it definitely clears some things up.
According to the docs, we should be using unique TDPO_FS names for each
node
we are backing up using TDP, correct?

After doing the query and some further investigation into the BACKUPS
table,
it appears we are getting this message because of a missing "-"....

When I do a select in the BACKUPS table, the LL_NAME shows up as:
c-3756527612-2003-0714-02

However, in the error we are getting, the name of the object is:
c-3756527612-20030714-02

Any idea why this is??

Steve
