The Question is:
When we reuse DLT tapes in our autoloader at the init command we receive the
following error:
$ init mkb400 BACKUP
%SYSTEM-F-MEDOFL, medium is offline
What is the process to correctly reuse a tape in Open VMS (BTW the tape wasn't
write protected)?
Thanks
The Answer is :
The default behaviour for dismounting tape media involves an operation known
as an unload. Akin to the dismount of traditional reel-to-reel media, DLT,
DAT and other cartidge media is left in a drive state where the operator must
effectively remove and insert a cartridge to enable access. This interlock
prevents software from unintentionally overwriting media during a volume
change.
If the use of DCL commands such as DISMOUNT/NOUNLOAD -- and also see the
MOUNT/NOUNLOAD command -- and assuming that removing and reinserting the
media does not resolve this behaviour, please contact the support center
directly. Expect to be asked which ECOs you have installed, and which DLT
tape drive is involved.
