All,
I've recently been having issues with a large Oracle DB Backup (2TB.)
Because of the application criticality we can only run this during the
weekend, and its failed several weekends in a row. Basically the errors
I am getting in Netbackup vary from 84 Media Write Errors to Errors 6 &
54 - Unable to Communicate with Client. The media however if used in
another backup is not bad, and I've tired now for several weeks using
different tape drives. I'm thinking this is some sort of an RMAN /
Netbackup communication issue.
The RMAN log always looks like this...
RMAN-10035: exception raised in RPC: ORA-19502: write error on file
"MDS1_bk_22057_1_584295994", blockno 183521025 (blocksize=512)
ORA-27030: skgfwrt: sbtwrite2 returned error
ORA-19511: VxBSASendData: Failed with error:
Server Status: Communication with the server has not been iniatated
or the server status has not been retrieved from the server.
RMAN-10031: ORA-19624 occurred during call to
DBMS_BACKUP_RESTORE.BACKUPPIECECREATE
But NBU is reporting Media Errors and Client Communications issues.
Any ideas?
-Jonathan

Well, it can be de-assigned and reassigned.
but you may get problems with error code 94's
How to do it? Check out the how to fix error code 94's
Media Manager error 94: "Volume not in specified pool" - scenarios and
solutions http://seer.support.veritas.com/docs/247898.htm
personally, I would just do a bpduplicate and make the duplicate the
primary copy and then expire copy 1.

That is EXACTLY what I told them!! (people who know better!!)
Sure this was the case, but my understanding is this:
1) When a Media ID (or volume if you want to call it that) is assigned
to a
Volume Pool, its stuck there
2) The Volume will STAY here until its expired or manually expired or
deassigned
3) There are valid images on the media - trying to deassign could lose
them
(or cause issues)
4) Should plan better when using Volume Poole
Any comments welcome

I don't think you can change volume pools of a tape if it has images on
it.
It normally needs to be expired first, which of course will mean it can
be
re-used.
