[comp.sys.hp] Backup messages

pearmana@prlhp1.prl.philips.co.uk (Andy Pearman) (07/29/88)

We have an HP 9000-350 running HP-UX 5.3

When doing a backup onto cartridges using a 35401 cartridge unit
that has an 8 slot magazine, we sometimes get the message :

tcio: cannot verify tape /dev/update.src; errno 5

Does anybody know what this means ?  I believe all HP cartridges are
pre-formatted.  Does this mean it is trying to read a header or
something.  If so, in what way are they pre-formatted ????

Problem is that we leave our backups running overnight unattended, and
when we do a full backup onto about 5 cartridges it makes it very
difficult to track down which cartridge is at fault.

Also, having tracked down the faulty cartridge, is it possible to
re-format it for later use ???

Thanks if anyone can help,  Andy.

You have a problem with the tape.  I would re-certify the tape or merely
discard it.  If it seems to be happening "somewhat often",  I would start
to suspect the drive.

That is true.  They are all preformatted, but not all are certified.
We recommend running "mediainit -r" when a new uncertified tape is 
received.
