Netbackup 4.5mp6 on Soalris 8.

I have 2 LTO drives in my system but a backup just fails to mount a tape
in the first drive and just downs it. I have no idea why and cant see in
the logs. I have log level set to 4 and have been looking in the bptm
log but dont see anything obvious.

There is nothing in the drive also like a stuck tape.

Where do i look to find if the drive is at fault or not?

Some info below taken while the backup had started. The Drive was Up
originally.
