Problem:
    Lots and lots of tapes reporting errors when, auditing, copying, moving
data from them...

06/23/03   10:52:37      ANR9999D pvrntp.c(4586): ThreadId<15> Invalid
block header read from NTP drive DRIVE5 (/dev/rmt/10st).(magic=5A4D4E50,
ver=5, Hdr blk=1450 <expected 1451>, dbytes=262096 <262096>)

(Thus thousands of files on several tapes are unreadable)

TSM Server 5.1.6.3 on Solaris 9 (Sun V880 server)
IBMtape 4.0.7.3
8 LTO2 drives in IBM 3584 library (SCSI not Fiber attached) ( firmware
version 3641)

Hmm, all my testing of filling/restoring a few tapes of data said I could
backup/restore fine...
But the day after the system goes into production and we start moving real
data to these tapes, whammo..

Tivoli support said to turn on CRCchecking.
I say, uh yeah, I already know my data is bad.

Looks like I gotta try and figure out which drive/disk/scsi card is causing
the problem myself.

Any suggestions?

Thanks
