I am changing the multipathing software on my storage array. I have EMC AX4-5 storage array and mpxio has been handling the multipathing. Well the server has been getting more load lately and I am noticing mpxio is not load balancing very well so I was going to change to EMC PowerPath. Well when I changed to PowerPath it changed the /dev/dsk to something else and I couldn't figure out how mount my zfs filesystem. Any ideas how I can do this without losing all my data in the zfs pool?
ZFS pool independ of disks names.
What current state of pool ? ( zpool status )
You can try found what pool available now ( zpool import ) and import back required pool ( zpool import <pool_name> )
