The way you have it set up I would expect 3 jobs to run at any one time (one to each drive) with the remainder Q'ing. Unless you have a max jobs per policy set to one which is another area you could check.
Any idea where can i check that setting ?
cmdline again would be good . Then again I dont remember explicitly setting that.
Is this setting tied to per policy or it like a 'global' setting ?
Also, you mention same volume pool - could it be that you have a max number of partially full media set? (altho' having said that I'm not sure at which release of NetBackup that this setting became available)
where can i check that as well ?
Actually I can do a positive control by
by queuing some jobs from different policy, when i m back at work tml.
will keep you guys posted
did you re probe the drives after you changed it, it seems to be global database stale issue, removing and reconfiguring drives will definetly solve the issue
