Hi Kyle,
Except that in the case of spares, you can't replace them.
You'll see a message like the one below.

cannot replace c1t5d0 with c2t5d0: device is reserved as a hot spare

I'm using Solaris 10u6 updated to u7 via patches, and I have a pool
with a mirrored pair and a (shared) hot spare. We reconfigured disks
a while ago and now the controller is c4 instead of c2. The hot spare
was originally on c2, and apparently on rebooting it didn't get found.
So, I looked up what the new name for the hot spare was, then added
it to the pool with "zpool add home1 spare c4t19d0". I then tried to
remove the original name for the hot spare:
r...@box:~# zpool remove home1 c2t0d8
r...@box:~# zpool status home1
pool: home1
state: ONLINE
scrub: none requested

c2t0d8 UNAVAIL cannot open
c4t19d0 AVAIL
errors: No known data errors
So, how can I convince the pool to release its grasp on c2t0d8?
Have you tried making a sparse file with mkfile in /tmp and then ZFS
replace'ing c2t0d8 with the file, and then zfs remove'ing the file?
I don't know if it will work, but at least at the time of the remove,
the device will exist.

Thanks!
