Original question is below. I only got one response to this question and
it really didn't provide the answer. I basically have 8 disks all
initially running at 40MB/sec. The disks are set up mirrored, 4 disks on
one mirror, 4 on the other. When some disk intensive processes run
(backups, finding/removing core files) several of the disks on one half of
the mirror slow down to 20MB/sec and even 10MB/sec. I was asking if there
was a way, short of rebooting, to reset these devices back up to their
maximum speed of 40MB/sec. Apparently there is no way, other than to
reboot, to get these devices back to maximum speed.
