I''m having following issue .. i import the zpool and it shows pool
imported correctly but after few seconds when i issue command zpool list .. it
does not show any pool and when again i try to import it says device is missing
in pool .. what could be the reason for this .. and yes this all started after i
upgraded the powerpath
abcxxxx # zpool import
pool: emcpool1
id: 5596268873059055768
state: ONLINE
status: The pool is formatted using an older on-disk version.
action: The pool can be imported using its name or numeric identifier, though
some features will not be available without an explicit ''zpool
upgrade''.
config:
emcpool1 ONLINE
emcpower0c ONLINE
abcxxxx # zpool list
no pools available

This is not related to pool on-disk version though. victor> abcxxxx # zpool import > pool: emcpool1 > id: 5596268873059055768 > state: ONLINE > status: The pool is formatted using an older on-disk version. > action: The pool can be imported using its name or numeric identifier, though > some features will not be available without an explicit ''zpool upgrade''. > config: > > emcpool1 ONLINE > emcpower0c ONLINE > abcxxxx # zpool list > no pools available
