Not yet for DSS-G unfortunately. However even if they are, it means
someone thought it was an acceptable idea at some point.

The issue I have is what I want to do is reserve a set number of disks 
per tray/enclosure as spares. Ok not actual disks but the capacity of a 
disk as a spare. As of last February that was not possible, I had to 
mess about creating and destroying the vdisks till I got where I wanted 
to be. What a palaver that was.

I was also super unimpressed that the scripts throw a wobbler because my 
two DSS-G servers where named gpfs1 and gpfs2 which was not a problem on 
4.2.x and not actually documented anywhere.
