Dear managers,
one of our servers (X4240) shows a faulty disk:
-bash-3.00# zpool status
pool: rpool
state: ONLINE
scrub: none requested
config:

Hi Andreas,
Good job for using a mirrored configuration. :-)
Your various approaches would work.
My only comment about #2 is that it might take some time for the spare
to kick in for the faulted disk.
Both 1 and 2 would take a bit more time than just replacing the faulted
disk with a spare

Hi all,
zpool add tank spare c1t15d0
? After doing that c1t6d0 is offline and ready to be physically
replaced?
Yes, that is correct.
Then you could physically replace c1t6d0 and add it back to the pool
as
a spare, like this:
# zpool add tank spare c1t6d0
For a production system, the
Andreas,
I think you can still offline the faulted disk, c1t6d0.
The difference between these two replacements:
zpool replace tank c1t6d0 c1t15d0
zpool replace tank c1t6d0
Is that in the second case, you are telling ZFS that c1t6d0
has been physically replaced in the same location. This would
Hi Cindy,

OK, here it gets tricky. I have

Dang. This is a bug we talked about recently that is fixed in Nevada and
an upcoming Solaris 10 release.
Okay, so you can't offline the faulted disk, but you were able to
replace it and detach the spare.
Cool beans...

I believe there are a couple of ways that work. The commands I've
always used are to attach the new disk as a spare (if not already) and
then replace the failed disk with the spare. I don't know if there are
advantages or disavantages but I also have never had a problem doing it
this way.
If her adds the spare and then manually forces a replace, it will take
no more time than any other way. I do this quite frequently and without
needing the scrub which does take quite a lot of time.
