Tape NOT work after Hardware Error

Hi all,


I have a HP Ultrium 6-SCSI SAS tape connected to marvell SAS HBA under fedora linux 19 x64 (3.10.9-100.fc18.x86_64).

And when I achieve about 20GB data to the tape.


time tar cf /dev/st0 dat


It failed in the middle:

tar: /dev/st0: Cannot close: Input/output error
tar: Exiting with failure status due to previous errors


real    4m11.862s
user    0m3.403s
sys    0m43.625s

and the kernel reports:

[ 2896.932143] st0: Sense Key : Hardware Error [current]
[ 2896.937403] st0: Add. Sense: Internal target failure

Following is full kernel message from driver loading to error occurred:

And then I reboot the machine and found that the driver did not detect the HP tape device.


And I shutdown the tape and start it again.

Found the the fan is working, but no motor's noise and no LED flashing or light on.


Is there any body know what happened to the tape and what can I do?
