# = Extnl Q’ing % = CPU time,
* = Disc time, + = CPU contention,
~ = Other contention.
NOTE: An exclamation point (!) following a Volume name indicates
that both drives of the mirrored pair comprising the volume
were primaried through the same (Channel:Controller); the
volume was therefore performing serial writes.
L = Lock waits (requests blocked).
