Thank you Kern, Phil.
It's pretty clear to me what a Used status means: when a volume reaches its maximum duration time (i.e. Use Volume Once, Volume Use Duration). But it wasn't clear the difference with Full status.
If using tapes I could guess that a volume may have a Full status when the physical media is actually full (i.e. 1.5 TB for a LTO-5 tape), but what about File volumes? If I use "Maximum Volume Bytes = 10G", will my volumes get the Full status when they reach 10 GB of data?
