For any tape you can't read, the head alignment on the drive differs enough
from that of the drive that created it to make it unreadable.  It is never
very clear which is "wrong".  You might try to determine which drive can
record tapes that can be read by the most drives, and which drive rejects
tapes from the most drives.  The former would probably be your "best" drive
and the latter your worst.  Another approach would be to get a tape that is
from a known good source (an HP software distribution tape?) and see which
drives can read it.  Third choice: describe your problem to your service
provider, and let then determine which ones are in need of replacement.

Subject: 5 Tape Drives (or, Fox, Hen, and Sack of Corn)


I'm having a problem with a DDS-2 tape drive on a test machine
reading tapes from 3 of 4 DDS-2 tape drives on our production
machine.

Since tapes produced from 3 of the 4 tape drives fail on the
test machine, my first  reaction is that the test machines tape
drive has gone bad.

What bugs me is it still reads tapes produced on 1 of the 4
tape drives on the production machine.  Does this mean that
one of the production tape drives is bad also?  It can still
read the tapes from the other 3 drives.

The production machine can read tapes on all drives made from
the test machine drive.

What happens if I replace the drive on the test machine and
it still fails to read tapes from the 3 production machine
drives.

I'm also afraid it may be a firmware conflict.

I'm tempted to replace the one drive that the test machine
can still read from just to see if it starts failing to
read them too.

I get the error as follows:

VSTORE ENCOUNTERED ERROR READING MEDIA LABEL ON LDEV 7. (S/R 1278)
VSTORE IS ABORTING BECAUSE IT IS UNABLE TO READ A VALID STORE LABEL (S/R
1937)

STORE aborted because of error. (CIERR 1090)

Not that I know.

You probably need to do a bit more checking to see if the graphical
interface requirement can be split between the 3000 and another
workstation. If not, that's a fundamental piece lacking.

If the answer is yes, wanna try the port under my mentorship? (The more
people that can know how to do this ... the better it is for the HPe3000
community).

Has anyone tried porting this yet?
