For this reason we run a backup stg from the primary disks to copytape pool
before we do migration.  If the copytape is damaged by a tape drive, the
data is still on disk.  If the primary tape is damaged during or after
migration then there is the good copytape.

So the question is do you have a copytape of the data?

If so then you can do a "restore vol xxxxx preview=yes" where xxxxx is the
destroyed tape and the system will send to the actlog what tapes are needed.
Then these tapes can be made available (i.e. called back the ones that are
offsite).  If there are some offsite we mark all tapes needed as
unavailable.  When we have them onsite and checked in, we mark them all
readonly.  Now you can issue a "restore volume xxxxx".  This should recreate
the damaged tape.  Also once all the volumes are checked in, the restore can
be started if necessary.

If you do not have a copytape, then you are in a bad position.  If the data
is no longer on the server and your primary is not readable, I do not have
any good words for you but sorry.

Subject: Procedures to follow after a drive with a stuck tape is replaced --
3584 library


The other day I had to replace one of the drives in my 3584 library because
a tape was jammed in it.  This tape was being written to by a migration
process when it jammed (during daily processing).  The procedure went on to
complete successfully, but a q libvol shows that the tape is still in the
library in a private status even though it has been destroyed.  Last night I
had a restore fail (I'm guessing some of the data was on the tape that got
stuck?)

I basically need to know what procedures / commands need to be executed once
a tape has been destroyed to ensure that the data on that tape is available
on another tape.

I figure an audit library will make it recognize it's gone, but how do I
deal with the data?

Thanks in advance,
Kevin
