Media is not getting unfreeze
I m working on 6.5.6 environment. There was a restore for a RMAN backup and the tape required was called from Iron Mountain.
I froze the tape yesterday so no other backup process shd be able to use it.
Today I started the restore but its was not getting successful. Then i remember that i need to unfreeze the media first.
I cancelled the restore and confirm with the DBA if its cancelled from their side too.
Now as i m trying to unfreeze it its saying media in use. Can any one help??????
See this TN for steps to release nbrb allocation: http://www.symantec.com/docs/TECH126575
use 'nbrbutil -dump' to find MDS allocation, then 'nbrbutil -releaseMDS <MediaKey>'.
Just for the record NBU will not write to a frozen tape, but can still read from it. No need to unfreeze first.
Rather suspend media in future - backups will not be written to it, but will be normally recycled once all images have expired. Frozen tapes remain frozen, even when all images have expired.
