It could be couple of things...

Look at
1. Total server parallelism setting (ours is set to 64 w 4 LTO-4 Drives, 8 
target sessions per drive).
2. Target sessions per drive (the upgrade may have caused this # to be reduced, 
so it thinks it needs more drives to accommodate the total concurrent sessions 
it is attempting to run).
3. Parallelism setting of the running groups.... (do they add up to more than 
#2 above ??)

Hello,

Recently, our server is asking always for 1 writable volume when it has 
all 2 tapes drives with a tape inside and writing to them.

At the beginning of the backup it says "writing for 3 writable volumes" 
and after mounting 2 tapes in the 2 drives, the message for 1 extra 
volume is in the alert window.

Is this a new behaviour in the 7.6.1 versin? (we've recently upgraded 
from 7.5.3 where we haven't seen this message during the backups, only 
at the beginning while Legato mounts the tapes needed).

Thank you.
