IBM 3590 Tape Drive, Ubuntu Sever, MT read/write error
I have a IBM 3590-H1A tape drive, and I'm trying to read some tapes.
I'm running the lastest (8.10) Ubuntu server edition, a fresh install. If I run Code:
sudo mt -f /dev/st0 status Code:
drive type = 114 Then when I try Code:
sudo tar -xvf /dev/st0 Code:
tar: /dev/st0: Cannot read: Input/output error So basically the same error. Is there anything I can do? |
It looks like you have a blank tape.

Definitly not a blank tape. I tried several others that are supposed to contain data, and they all output the same error.
Any other ideas? |
If you're trying to run:
Code:
sudo tar -xvf /dev/st0 Code:
sudo tar -xvf /dev/st0 /some/path/to/file |
The tapes are all write protected, is this a bad thing? I'm only trying to get data FROM the tapes, I denfinitly do not want to write onto them.
Not sure what the arguements for cpio would be, any help? Also, that alternate tar command gave the same error. Thanks for you time! |
Yes you need to specify the files to restore or a wildcard.
tar -zxvf /dev/st0 * or a /path/file |
Thanks for the reply kentyler, but when I run
Code:
tar -zxvf /dev/st0 * Code:
tar: /dev/st0: Cannot read: Input/output error |
Some additional ideas.
IMHO you might have a hardware problem. You can try listing the contents tar -tvf /dev/st0 Might want to try testing the drive by reading/writing with a blank tape. Was the data written using the same drive? |
Now I'm trying the tape drive with a fresh install of Red Hat Enterprise Edition 4.
More info, running "IBMtapeutil -f /dev/st0 status" returns the following; Code:
Generic ANSI SCSI-2 tape drive Running "tar -tvf /dev/st0" returns: Code:
tar: /dev/st0: Cannot read: Input/output error Quote:

Test the tape
Add files to the tape to see if the hardware works then try to restore the files.

IBM 3590 Errors - diagnostics
Looks like you need to run some diagnostics. There is a spec and software called TapeAlert. There is a $90 software product from santools that runs full diagnostics, monitors tape/autochangers, and gives you error results and such. The code is ported to LINUX on 32 and 64-bit chips, links to some tape-related diag screen dumps are http://www.santools.com/smart/unix/m...erttesting.htm or just http://www.santools.com/smart/unix/manual for the main page.
I know it will work on IBM 3590s. |
I realize this is a fairly old post and you've probably rectified the problem by now but maybe you could call up the manufacturer. Usually the systems come with lifetime tech support and I'm sure they could help you out with trying to get this data read. I personally am annoyed by most call in tech services but if you can get past the annoying part they can usually figure it out for you. For more information on the IBM 3590 H1A model you can visit our site at http://www.cpuinc.com/3590-tape-driv...1-tape-drives/. You can also email us with tech support questions at techsupport@cpuinc.com. I hope this helps.
