SUMMARY: DLT8000 not unmounting tape

[Kevin Davidson]

Thanks to everybody who replied. Suggestions mainly focused on either the
drive or the media being bad and needing replacement. However, after a two
hour trip across the city to the datacentre, the problem turned out to be
human error on the part of the NOC staff responsible for changing the tapes!

Subject: DLT8000 not unmounting tape

Hi everybody,

I have a DLT8000 which won't unmount the tape that is currently loaded.

According to the OS there is no tape mounted:-

$ mt -f /dev/rmt/0 status
/dev/rmt/0: no tape loaded or drive offline

I have the following error in /var/adm/messages

WARNING: /pci at 1f,4000/scsi at 3,1/st at 4,0 (st11):
Error for Command: write                   Error Level: Fatal
Requested Block: 716224                    Error Block: 716224
Vendor: QUANTUM                            Serial Number:  P  "
Sense Key: Media Error
ASC: 0xc (write error), ASCQ: 0x0, FRU: 0x0

It looks like the backup last night filled the tape.

Any ideas, or should the drive be replaced?

Thanks in advance, will summarize the responses.

Kevin
