Use the following procedure to recreate the ZFS root pool or to create an alternate root pool. The zpool create command automatically creates a EFI (GPT) labeled disk with the correct boot information.
Issue the format command to launch the Format utility. The following is a sample output of the command.
# format Searching for disks...done AVAILABLE DISK SELECTIONS: AVAILABLE DISK SELECTIONS: 0. c3t0d0 <FUJITSU-MAV2073RCSUN72G-0301 cyl 14087 alt 2 hd 24 sec 424> /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/sd@0,0 1. c3t1d0 <FUJITSU-MAV2073RCSUN72G-0301 cyl 14087 alt 2 hd 24 sec 424> /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/sd@1,0 2. c3t2d0 <FUJITSU-MAV2073RCSUN72G-0301-68.37GB> /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/sd@2,0 3. c3t3d0 <FUJITSU-MAV2073RCSUN72G-0301-68.37GB> /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/sd@3,0
# zpool create -B root-pool mirror disk1 disk2
where root-pool is the name of the root pool.
The following example sets and mirrors rpool on c3t0d0 and c3t1d0.
# zpool create -B rpool mirror c3t0d0 c3t1d0
