Many replies...Thanks all,
Replies mainly condemned the hardware due to the fact it was an "lbolt"
error received.
I moved the cables around, reseated the connectors and ran the cleaning tape
twice.
It seems to have worked as I have an fbackup running for over an hour now
without error.
I will be keeping an eye on it as this drive is old. When the time comes,
the cable goes as well.
REPLIES:
Either your dds drive is bad or your scsi card is bad... From the looks of
the errors, I tend to agree with your assessment on the dds drive.
I would first check the SCSI cable for any kinks or broken pins. I would
also suspect the SCSI Terminator, if the drive is an external module.
I'd say your DDS3 drive is toast.
If your still under warranty/support then call HP to replace the unit.
If the system is out of warranty/support then consider buying a refurbished
unit and replacing it yourself (it isn't that difficult).
The lbolt errors usually mean a SCSI bus error which could be caused by
the tape drive.
Check your terminators and cable connections for snugness.
looking at the message again you have TWO devices reporting lbolt errors
the dev cd011080
and dev cd 0110c0. Could be another device is having a problem.
You can be confident that lbolt errors (parity errors, etc) are definitely
hardware,
not software. Note that bad tapes and dirty heads will cause these errors
too.
DDS3 is an older technology so replacement drives are cheap and if the drive
is used daily, about 2 years is all you can expect for reliable operation.

lbolt scsi errors are mostly due to the cable, the connectors or the drive
itself, so you may well be right. But try to refit the cable again, make
sure all connections are tight, that the bus is well-terminated, etc. in
general, try to eliminate all other possible causes. It's cheaper to replace
a cable then a DDS drive.....
the device equates to cd=205 (stape device) , so you have a hardware issue
with the tape drive. If you've eliminated any possible problem with the
tape itself, then maybe you need to check into replacing the tape dirve.
Check cabling and scsi termination, but yes most likely its a faulty
drive, especially if it has been OK for a while, not disturbed recently.
