Don't know why zfs cannot open device?
itsm-mpk-2# zpool import
pool: canary
id: 9275088414963579563
state: ONLINE
action: The pool can be imported using its name or numeric identifier. The
pool may be active on on another system, but can be imported using
the '-f' flag.
config:
canary ONLINE
c1t0d0s3 ONLINE
itsm-mpk-2# zpool import canary
cannot import 'canary': pool may be in use from other system
use '-f' to import anyway
itsm-mpk-2# zpool import -f canary
cannot import 'canary': pool exists
itsm-mpk-2# zdb -L /dev/dsk/c1t0d0s3
zdb: can't open /dev/dsk/c1t0d0s3: error 22

This suggests that both vn_open('/dev/dsk/c1t0d0s3') and
ldi_open_by_devid('.....') are failing for this device. Are you sure
that this device exists and is readable? What does 'zdb -L
/dev/dsk/c1t0d0s3' show?
You can try a 'zpool export' and 'zpool import' to see if it finds the
device, but ZFS should be able to handle this type of devid change.
