Re: The device is offline
First thing to do is check if the cleaning people actually unplugged the tape drive.
Next make sure the cabling is secure and undamaged.
You may need to boot your system to get everything back online.
There is the possbility the drive actually failed. Maybe its get a flashlight take a look time.

Re: The device is offline
I have checked the device is not unplugged and reboot the machine.
I run this:-
mt -f /dev/st0 stat
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
DR_OPEN IM_REP_EN
Then this command mt -f /dev/st0 rewind
/dev/st0: Input/output error
mt: The device is offline(not powered on, no tape ?)
It's bcos the device totaly failure ask you said?

Re: The device is offline
I think the error message from tape is saying that the door is open !
Perhaps the tape is not seen as close properly is the tape in properly.
There could be a long delay before the tape actualy rewinds !!
But then as SEP said it could be a call for fiels service.
