Hi all,
We are having a terrible time with our StorageTek 9714 and our 6 DLT7000
tape drives. In the last 5 weeks we have had 5 tape drives replaced mt3,
mt4, mt3(again), mt0, mt2. The symptoms are that all the lights come on and
blink and a tape is stuck in the drive, on two separate occasions the tape
has been destroyed, physically mangled. StorageTek just keeps replacing the
drives. About three weeks ago, and three tape drive replacements,
StorageTek was out and updated the software on 9714 and the tape drives to
the current levels ( at this time I don't know exactly what that is ). We
are running ADSM Server 3.1.2.13 on a G40 with AIX version 4.3.2.
I have 3 SACS adapters with the following config.: ( IBM just updated the
adapters to the latest levels as well! )
scsi0 - mt0
mt1
mt5
lb0
scsi1 - mt2
internal devices hdisk0, hdisk1, cd0
scsi2 - mt3
mt4
These are the errors I'm getting..... I know they are different types but we
are getting these all the time on different drives. I have a drawer full of
DLT tapes that I have taken out of the library due to excessive errors.
These tape are expensive and I find it hard to believe it's all the tapes!
We use Quantum and DLT - DLTtape IV tapes.

Is there anything to check within ADSM or on AIX ( device level, density,
block etc. ) that might be causing so many tape issues?
Is anyone else have issues similar to this?
Any help would be greatly appreciated, Thanks!
