Re: Creating Device Description

[Kevin Corcoran <kevin_corcoran@xxxxxxxxxxxxxxx>]

This is some years ago for a previous employer so memory is sketchy, but 
we used to have a similar issue, where occasionally BRMS would get 
confused and the tape library would become unusable. As far as I remember 
it would sometimes vary on but would still be unusable, or else it would 
refuse to vary on. I don't remember ever having to delete and recreate the 
device descriptions. If memory serves correctly, I used to resolve the 
issue by doing the following:

- vary off the tape library if not already varied off (TAPMLB03)
- vary on the tape device TAP03
- vary off the tape device TAP03 again
- vary on the tape library TAPMLB03

and then the library would become usable again.

Not sure this is even the same issue, and could never find any logic in 
why doing the above resolved the problem, but I guess you've nothing to 
lose by trying it.
I have some notes at home on dealing with various BRMS issues we 
encountered, I'll have a look later to see if the possible solution 
described above is correct, or for anything else that might be relevant.

Creating Device Description






Hi ,
 
We have BRMS installed on the AS400.The configuration of Tape Library/Tape 
Device is as follows:
 
Opt  Description       Status    
     TAPMLB03          VARIED ON 
     TAP03                 VARIED OFF
 
If the backup fails here and the tape library cannot be varied on again to 
start the backup,then what is the way to fix this issue.
 
I have heard about deleting the device description and recreating it but 
do not eaxctly know how to do it.
 
Please can anyone let me know the steps to create the device description 
and starting the backup. 
 
Many Thanks
Darell
