We need to see a little more detail to give you a clue on that one

The bptm log from the media server or an All Log Entries report for the time period when it was frozen

A few regular ocurrances of this - often a tape that has been used as a catalog backup tape and then put into a normal backup pool - NetBackup detects that it has a catalog backup on it and immediately freezes it

It it is to be re-used it has to be labelled without the verify option selected

But lets see some logs first - if windows there may also be something in the application event log too

frozen media is S00309

from bptm I could find only the following strings about S00309. But error time was at 11:59.

OK - as you are on unix what is logged under your system messages? (/var/log/message?)

It is worth adding the VERBOSE entry to the vm.conf on yoru media servers (then restart ltid) and try using the taoe again so that we can pin down the error when it happens


The use of NO_SIXTEEN_BYTE_CDB is interesting - do you know why you have that on place?

You need to enable logging - bptm log folder on the media server is the 1st one you need.

If you don't have this folder yet, please create it.  In the meantime, run Tape Logs report.  Make Start date far back enough to include date/time that tape was frozen.
Use the filter to exclude Info in Severity column. Only Warning and Error level will remain.
Please save this report as .txt and upload here as File attachment.

The other file to check - /usr/openv/netbackup/db/media/error

Hello all.. I tried as you say.. It was very long time , to wait the policy to mount  actually that  mentioned media ,

I decided to leave it as frozen.. I will lost only 25 Gb..  next time none of the policy will mount it.
