After mirroring the device or zfs send install the bootblock installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0 |
First we need to get the lun paths, just run the below to get that
|

{0} ok show-disks a) /pci@500/pci@0/pci@c/SUNW,qlc@0,1/fp@0,0/disk b) /pci@500/pci@0/pci@c/SUNW,qlc@0/fp@0,0/disk c) /iscsi-hba/disk q) NO SELECTION |
Next get the disk id’s, just run the below to get that.

So the path is:

/pci@500/pci@0/pci@c/SUNW,qlc@0/fp@0,0/disk + @ + w50060e80164e9d1a + 10b:a (the a is because the / is in the s0 partition) |
Next lets try to boot, by running the below.
