DLT 8000 problem

[thebeatlesguru]

DLT 8000,7 session everyday,every session finshes same work everyday,however some time session is complete,some time session is complete/error or complete/failure
error is like following:
[Major] From: BMA@dbbak-lc "Drive 5" Time: 02/19/02 02:02:40
[90:54] /dev/rmt/9m
Can not open device ([16] Device busy)
i think if there is something wrong with DLT 8000,then it should have error everyday,cause everything is the same,but the error is not happen everyday,so i do not know why,can somebody tell me the reason?

Hi,

Is the tape drive part of a library or is it
standalone?

Hi,

I assume your using omniback going by the
error messages.
You could add a post-exec script like
this to your backup specification to see
what gets reported. Other than that it
could be a firmware issue, a locking of
the drive problem where you don't specify
a lock name for each logical drive for
each physical drive.

# Set Variables
set -x
exec 2>&1
FAIL_LOG=/tmp/omni_fail
PATH=$PATH:/opt/omni/bin
export PATH
# Check to see how the session completes
if [ $SMEXIT != 0 ]
then
echo "Session $SESSIONID Backup not successful" >$FAIL_LOG
env >>$FAIL_LOG
id >> $FAIL_LOG
omnirpt -report single_session -session $SESSIONID >> $FAIL_LOG
cat $FAIL_LOG | mailx -s "OmniBack session $SESSIONID failed" yourname@domain.com

Hi there.
Is it possible, that two different sessions try to access the same tape device at the same time ?
If one session is not finished yet and the next session tries to put a tape into this specific drive, you might have a problem.
Have you checked the session protocols ( messages ) for start and stop times ?

yes,i have thought about it,and checked the start and end time of every session,and there wasn't two different sessions try to access the same tape device at the same time.
