DLT 8000 problem

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?

Re: DLT 8000 problem

Hi,

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

Re: DLT 8000 problem

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.

Re: DLT 8000 problem

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 ?

Re: DLT 8000 problem

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.
