Ultrium tape problem
I have connected a new HP Ultrium 1-SCSI tape drive an rp3440 system running with HP-UX 11iv3 Spetember 2008 release.
Whenever I try to run pax, dd or tar on any of the tape device files it gives the followin errors -
With tar:
# tar cvf /dev/rtape/tape1_BEST /tmp/ifile
a /tmp/ifile 6 blocks
Tar: end of tape
Tar: to continue, enter device/file name when ready or null string to quit.
User entered a null name for next device file.
# dd if=/dev/rtape/tape1_BEST of=/tmp/ofile2
dd read error: I/O error
0+0 records in
0+0 records out
# tar tvf /dev/rtape/tape1_BEST
Tar: tape read error
With dd:
# dd of=/dev/rtape/tape1_BEST if=/tmp/ifile bs=512
I/O error
4+0 records in
3+1 records out
# dd if=/dev/rtape/tape1_BEST of=/tmp/ofile2
dd read error: I/O error
0+0 records in
0+0 records out
With pax:
x1131pa02# pax -w -f /dev/rtape/tape1_BEST /tmp/ifile
pax: write : I/O error
pax: A write error has occurred.
x1131pa02# pax -f /dev/rtape/tape1_BEST
pax: The archive is empty.
Please advice.
Thanks,
Sanjay

Re: Ultrium tape problem
a) We did not get your dmesg attachment.
Maybe it gives us more clues.
b) Apart from that, check these:
# ioscan -fnC tape (tape drive must be CLAIMED)
# ioscan -m lun
# diskinfo /dev/rtape/tape1
# mt -f /dev/rtape/tape1 rewind
# mt -f /dev/rtape/tape1 status
c) It is possible that the tape drive is
faulty or the tape itself is faulty too.
Also, try to use device /dev/rtape/tape1.
Maybe your DSF /dev/rtape/tape1_BEST was not
created correctly?

Re: Ultrium tape problem
Could even be improperly terminated tape drive.

Re: Ultrium tape problem
Problem was resolved after I replaced the SCSI cable to the tape drive.
