Recover bootdisk FC after crashed (solaris OS)

Recover bootdisk FC after crashed.
change bootdisk FC (fyi, default bootdisk on V880, V480, 280 are using FC, not scsi cable) :
1. boot from cdrom from OK prompt.
OK>boot cdrom -sw
2. mount boot partition.
#mount /dev/dsk/c1t0d0s0 /a
3. rebuild the device.
#drvconfig -r /a/devices -p /a/etc/path_to_inst
#cd /devices
#find . -print | cpio -pduVm /a/devices
#disks -r /a
#devlinks -r /a
4. check eeprom |grep boot-device, change to new device.
#luxadm set_boot_dev /dev/dsk/c1t0d0s0
5. check eeprom again, make sure it's changed.
6. reboot -- -srv

note: If you're using a new disk, restore all files from backup tape (ufsrestore or others) then do #3 to #5. Before #6 (reboot), you should install bootblock as follows :
#installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t1d0s0
