TransX -
It's not a full list of all of your drives.
You'd have to look at the partner view to see whether that drive is a spare for the partner.
You could unassign a spare drive(s) from the partner, then assign to this controller.
See the 'disk unassign' and 'disk assign' commands.
I hope this response has been helpful to you.
