SCSI TAPE: dev = 0xcd100140 I/O error during close

[Jonathon Valente]

I have been receiving the error message

SCSI TAPE: dev = 0xcd100140 I/O error during close

in my syslog for a couple of weeks now. I can not say that it is causing any real problems but it is annoying to keep getting errors in the syslog. This server has 6 tape drives attached to it. Can anyone help me identify which one it is and why I am receivng this error? Thanks!

It can be a problem if you many drives on one SCSI bus, causing bottleneck on it.

Check also if you use the no-rewind device file without the Berkley option.If not, when the device file is closed and you are positioned in the last file, then the tape is moved to the next file pointing to a not existing position.

Look in /dev/rmt for a tape device with a minor number of 0x100140

e.g.

ll /dev/rmt | grep "0x100140"

Hi Mahipati,
I tried to access that doc and received an error. Can you post it to the board for me. Thanks!

hi,
i had the same problem. the system is a l-class server running hpux 11.0 and two tape drives on a separate scsi channel. i think, that is not a hardware problem. i tried to get the document reported by Mahipati, however i can not receive it. can you send me the document or post it to the board ?

Have you changed to tapes from a different manufacturer? HP tape drives are notoriously picky about the tapes they use and I've seen this error if you use the "wrong" manufacturer's tapes.

hi,

i use only hp tapes on hp devices.
the drives a DLT4000 and BNCHMARKDLT1. the error occurs only on BNCHMARKDLT1.
