I have an HP Ultrium 448 tape backup that is being recognized without seeming issue on Ubuntu. I am able to see it at /dev/st0
.
When I issue mt -f /dev/st0 offline
, the tape ejects. When I issue mt -f /dev/st0 status
, I get:
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x42 (LTO-2).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN
When I issue tar -tzf /dev/st0
, I get:
tar (child): /dev/st0: Cannot read: Cannot allocate memory
tar (child): At beginning of tape, quitting now
tar (child): Error is not recoverable: exiting now
gzip: stdin: unexpected end of file
tar: Child returned status 2
tar: Error is not recoverable: exiting now
I suspect that this is because it was created with the Windows Server 2003 Backup
utility. I realize that I can leverage mtftar
to get these contents, but how do I get the raw backup data first? Eg, I can't seem to list the file content on the drive initially here. Do I need to pipe initiate some kind of read via mt
and then pipe that through mtftar
in order to see the data structures on the backup tape?
