But as per SUN, they have not mentioned to installboot block.
Is it required in Solaris 10??

15) Determine the device path to the boot devices for both the primary and mirror:
ls -l /dev/dsk/c1t1d0s0 /dev/dsk/c1t0d0s0
lrwxrwxrwx 1 root root 43 Dec 23 17:51 /dev/dsk/devices/pci@1c,600000/scsi@2/sd@0,0:a
lrwxrwxrwx 1 root root 43 Dec 23 17:51 /dev/dsk/devices/pci@1c,600000/scsi@2/sd@1,0:a
# eeprom "nvramrc=devalias rootdisk /pci@1c,600000/scsi@2/disk@1,0
devalias rootmirror /pci@1c,600000/scsi@2/disk@0,0"
(Please note the change "sd" to "disk" in using ls -l output.)
# eeprom "use-nvramrc?=true"
You can also change the boot-device values so that the system tries to boot from the mirror in case one of them is not available.
# eeprom boot-device="rootdisk rootmirror net"
16) Once the syncing is complete, test your system by removing the root disk.
