I have got 5 dedicated tape drives for NDMP on our master server which is running 5.1 MP5. I am finding that our NDMP backups are constantly failing with 52 errors, complaining about media being in a down drive, which is not the case or might get 84 - media write errors. This is only occurring for my NDMP backups and nothing else.
Checking the logs we are still getting media errors on NDMP backups (i.e. 84's) and also lots of errors like the following when a large number of media id's are rejected and then a status 52:-
05/06/2006 05:04:57 - Warning bptm(pid=12797) media id 601468 is unavailable (in a DOWN drive, misplaced, or not available for another reason), attempting retry with a different media id

05/06/2006 05:05:32 - Error bptm(pid=12797) media manager terminated during mount of media id 601555, possible media mount timeout
05/06/2006 05:05:32 - Error bptm(pid=12797) media manager terminated by parent process
05/06/2006 05:05:33 - end writing
timed out waiting for media manager to mount volume(52)
Has anybody see this before and do you have answer
Thanks
