I am having problem with one ZFS pool and the raid controller was moved around.
The OS is Solaris 10 8/07 X86.
All the drives are found by the OS, but ZFS can''t find two hot spare
drives for some reason. And the pool is unavailable. Here is what "zpool
status -x" shows:
pool: scrpool
state: UNAVAIL
status: One or more devices could not be opened. There are insufficient
replicas for the pool to continue functioning.
action: Attach the missing device and online it using ''zpool
online''.
see: http://www.sun.com/msg/ZFS-8000-D3
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
scrpool UNAVAIL 0 0 0 insufficient replicas
raidz1 UNAVAIL 0 0 0 insufficient replicas
c2t0d0 UNAVAIL 0 0 0 cannot open
c2t1d0 UNAVAIL 0 0 0 cannot open
c2t2d0 UNAVAIL 0 0 0 cannot open
c2t3d0 UNAVAIL 0 0 0 cannot open
c2t4d0 UNAVAIL 0 0 0 cannot open
c2t5d0 UNAVAIL 0 0 0 cannot open
raidz1 UNAVAIL 0 0 0 insufficient replicas
c2t6d0 UNAVAIL 0 0 0 cannot open
c2t7d0 UNAVAIL 0 0 0 cannot open
c2t8d0 UNAVAIL 0 0 0 cannot open
c2t9d0 UNAVAIL 0 0 0 cannot open
c2t10d0 UNAVAIL 0 0 0 cannot open
c2t11d0 UNAVAIL 0 0 0 cannot open
This is what the pool looks like when online noramlly:
pool: scrpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
scrpool ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c2t0d0 ONLINE 0 0 0
c2t1d0 ONLINE 0 0 0
c2t2d0 ONLINE 0 0 0
c2t3d0 ONLINE 0 0 0
c2t4d0 ONLINE 0 0 0
c2t5d0 ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c2t6d0 ONLINE 0 0 0
c2t7d0 ONLINE 0 0 0
c2t8d0 ONLINE 0 0 0
c2t9d0 ONLINE 0 0 0
c2t10d0 ONLINE 0 0 0
c2t11d0 ONLINE 0 0 0
spares
c2t12d0 AVAIL
c2t13d0 AVAIL
"zpool online" command does not work since no pool is available.
Any suggestions what I should to do to bring the pool back?

Can you really see them in format output correctly? If so then please check if the ZFS labels are still there with zdb -l / dev/rdsk/c2t2d0s2 etc Sami
