Nope, it was not there in 5.1

So you have 8 drives - and your storage unit is set to use 8 drives... correct?
And multiplexing for the storage unit is set to 4 - so you should be able to 
have 32 jobs running at once - 4 to each of the 8 drives. 4 x 8 = 32

So let's look at something else.
Are you running more than one job per client?  (multistreamed backups)

If so lets look at how many jobs per client are allowed.
Master server properties, Global Attributes
Maximum jobs per client -if this is one or 2 look at what jobs are running and 
which ones are queue.  Has that Client reached it's max number of concurrently 
running jobs?

The Maximum jobs per client property specifies the maximum number of backup and 
archive jobs that NetBackup clients can perform concurrently. Default: 1 job.


This can also be set per client - so if the Global is like 8 but you still have 
queue, again in the master properties look at Client Attributes
See if a client is listed here, if yes then look at the General tab and see if 
the client has be set to limit the number of data streams

The Maximum data streams property specifies the maximum number of jobs that are 
allowed at one time for each selected client. (This value applies to the number 
of jobs on the client, even if multistreaming is not used.)

sorry but i could not find "state details" as column in activity monitor , 
maybe its not there in 5.1. Also there is no value set on Max. Conc. Jobs in 
storage unit.

Yes it is configured to use all the drives. The client_connect_timeout value is 
4000 seconds.

Another thing which i noticed is that "Maximum multiplexing per drive" is set 
as 4 on storage unit. But multiplexing is set as 16 on policies. Could this be 
the reason for queued jobs? But at times i have noticed that 1 out of 8 drives 
is utilised and still there are approx 5-6 jobs in queued state and when i see 
job details there is nothing.
