Backup Problem with SCO Unix

[Arabatzis Pantelis]

I have two Proliant Servers (ML370G2 & ML370G1) and they have SCO Unix installed. Both of them have the same problem. When the backup
process is initialized, after 1 minute or so, an error message pops up saying that "the backup has failed, check if the dat tape is write protected and try again". I have replaced the DAT devices at both of them, but the problem is still there.
Any suggestions would be great. Thank you.

What version of SCO Unix are you using? WHat version of the EFS is installed? What software are you using to do the backups? What tape drive and cassettes are you using?

[Arabatzis Pantelis]

The SCO Unix version is SCO OPEN SERVER 5.0.5 ENTERPRISE EDITION. The EFS version is 5.1 and
the backup util is DRIVER D 160. The DAT devices are 12/24GB internal.

What product are you using to do the backup?

Can you post us the details of 'hwconfig -h | grep tape'. Taking note of the 'ht' field, do a 'hwconfig -h type='.

It might also be helpful if you give us the output of 'hwconfig -h | grep Stp'.

Have these tape drives ever worked in the past?

addendum ...

pls ensure your fw = L111 if not upgrade with LTT diag sw -> www.hp.com/support/tapetools/

fw avaliable ->
ftp://ftp.hp.com/pub/softlib/software1/co552/co-3162-1/

did you also check that the drives might not need recalibration (with a new piece of media) by checking in LTT running device analysis and checking the result tab ??

and the media -> how old is it ??

I suppose that the tapes are not old, but I'm not sure at the moment. But according to your
suggentions, it doesn't seem like a hardware
problem. Unfortunately I don't have the authority to make any software modifications on
these systems. If it is a software thing, there
are other group of people that will handle it.
I am authorized only for hardware problems. So,
I would like your opinion if you think that it's a hardware or a software problem. Thank you for your time.
