Note: NOM does not seem able to do the drive use reports if the drives
are SSO-ed

Subject: Re: [Veritas-bu] Drive utilisation in Netbackup
Well NOM can do this for you if your servers are 6.x. It has a couple
of
built-in reports, one for 'drives in use' (as in currently) and one for
'drive usage' for which you set a time frame, like 'last 24 hours' or
'last 7 days'.
I agree that I've seen people use DIY with vmoprcmd triggered at regular
intervals. Also, some people use that just to 'UP' down drives
automatically every hour or so. It woould work for pre-6.x versions as
well, but is a bit more challenging than NOM if you have a number of
domains.
Another approach if you use FC connected drives is think what tools you
have that can extract reports from the SAN switches. If you use Brocade
you could run their free SAN Health tool for a limited period. Once you
work out which ports the drives are connected to you can make a sensible
extract from the Excel it generates. What that gives, which is
otherwise
hard to get, is the actual throughput at the fibre port, so it doesn't
matter how many jobs are MPX to the drive.
You can infer utilisation (as in used/idle) from seeing the peaks &
troughs in the graphs.
Other framework products can also get this information using SNMP.
