Hi , I had a zfs pool which i exported before our SAN maintenance and powerpath
upgrade but now after the powerpath upgrade and maintenance i ''m unable
to import the pool it give following errors
# zpool import
pool: emcpool1
id: 5596268873059055768
state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.
see: http://www.sun.com/msg/ZFS-8000-3C
config:
emcpool1 UNAVAIL insufficient replicas
emcpower0c UNAVAIL cannot open
# zpool import -f emcpool1
cannot import ''emcpool1'': invalid vdev configuration
any idea what could be the reason for this ?

could it be possible that your path changed? just do "format" CTRL+D and look if emcpower0c is now located somewhere else. regards daniel Ketan <no-reply at opensolaris.org> writes:> Hi , I had a zfs pool which i exported before our SAN maintenance > and powerpath upgrade but now after the powerpath upgrade and > maintenance > i ''m unable to import the pool it give following errors > > # zpool import > pool: emcpool1 > id: 5596268873059055768 > state: UNAVAIL > status: One or more devices are missing from the system. > action: The pool cannot be imported.

thats the problem this system has just 2 LUNs assigned and both are present as you can see from format output 10. emcpower0a <DGC-RAID5-0326 cyl 65533 alt 2 hd 16 sec 890> /pseudo/emcp at 0 11. emcpower1a <DGC-RAID5-0326 cyl 51198 alt 2 hd 256 sec 16> /pseudo/emcp at 1 -- This message posted from opensolaris.org

zpool cache is in /etc/zfs/zpool.cache or it can be viewed as zdb -C but in my case its blank :-( -- This message posted from opensolaris.org
and regarding the path my other system has same and its working fine see the
below output
# zpool status
pool: emcpool1
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using ''zpool upgrade''. Once this is
done, the
pool will no longer be accessible on older software versions.
scrub: none requested

Thanx to all for the efforts but i was able to import the zpool after disabling first HBA cards do not know the reason for this but now the pool is imported and there was not disk lost :-) -- This message posted from opensolaris.org
