Situation: OES Linux SP1 on a DL380 with internal RAID and internal hot-pluggable dat72.
At first the tape device wasn't seen by the OS, so I added the lines mentioned in TID10094676 to the boot.local.
Then I added mt -f /dev/st0 setblk 4096 to get the correct blocksize.
Still getting errors on the device:
e.g. dmesg says:
Error with sense data: Current st0: sense key Aborted Command.
mt with status says:
Tape block size 4096 Density code 0x47 (unknown).

Any clues where to look??
