can somebody give me an idea on this message on my syslog.log :

SCSI TAPE: dev = 0xcd053040 I/O error during close

[Patrick Wessel]

Your tape drive 0xcd053040 had a problem. 0xcd053040 is the following drive:

cd: major#
05: bus#
3: target
0: LUN
40: flags

you will find the bus with the command:
ioscan -fC ext_bus

[Ivan Coenegrachts]

Here is a summary of possible causes :

- software : are SCSI-patches correctly installed ? Check with "swlist -l fileset -a state" and see if all patches are 'configured'.

- try "ioscan -fnCtape" to see if HW is well recognized.

- At time of the error, were diagnostics running ? ("ps -ef | grep diag"). If so, see with [x|m|c]stm if there are entries in /var/stm/logs/os.

- Dirty tape head : clean head w/cleaning cartridge.

- Bad tape media - Try using various tapes. Make sure tape drives are supported. Use DDS quality tapes.
