Hi Tim,
I'm not sure why your spare isn't kicking in, but you could manually
replace the failed disk with the spare like this:
# zpool replace fserv c7t5d0 c3t6d0
If you want to run with the spare for awhile, then you can also detach
the original failed disk like this:
# zpool detach fserv c7t5d0
I don't know why the device name changed either.
See a similar example below.
Thanks,
Cindy

Is there a way to manually trigger a hot spare to kick in? Mine doesn't
appear to be doing so. What happened is I exported a pool to reinstall
solaris on this system. When I went to re-import it, one of the drives
refused to come back online. So, the pool imported degraded, but it
doesn't seem to want to use the hot spare... I've tried triggering a
scrub to see if that would give it a kick, but no-go.
r...@fserv:~$ zpool status
pool: fserv
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas
exist for
the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.
