Hi,
I got a problem on my backup server again and need help. I have read all
the manual, searched on the web and post the message on other groups but
no answer yet. Thanks in advance for any suggestion.
The backup acted weird on last Sat while I was replacing the tape. At first,
I could not remove the volume index out of the pool. After I fixed
this problem and tried to label the tape. It gave me the error on each
tape, said that bad file number. I have to redo the labling again and
again. I have only successfully finished labling three tapes. At the
fourth tape, it took more than half an hour, but was still not done. So I
cancelled the operation of labeling. The problem happened during the
cancelling. The scsi error occurrs, I got the error message: Read open
error, I/O error. The autochange stops in the middle of the CY-TL8-2015
tape library subsystem. The light is green for the autochanger at that
time. Then I opened the door of the autochanger driver, found the tape is
still mounted, but the autochange was hang in the middle. After I closed
the door, the light of the autochager become in red. Then I checked the
log file , have some error messages like this:
Sep 27 17:32:17 beverly unix: SCSI transport failed: reason 'timeout':

The server is running SUNOS 5.6 with RAID 5 external hard disks and
backup file is solstice 5.1.
I have checked the /kernel/drv/st.config. Nothing was wrong there.
Could anyone give me a hint?
Mei
