booting from the mirored disk

Hai,

I used the following command to install bootprogram on mirror disk, after creating all metadevices.

#installboot /usr/platform/SUNW,Ultra-4/lib/fs/ufs/bootblk /dev/rdsk/c4t3d0s0

ok nvalias mirror /pci@6,4000/scsi@4/sd@3,0:a

SUNW,Ultra-4 is the system architecture

mirror is the alias name given to the disk c4t3d0s0, which is going to used as mirror to OS.

After this I tried using as below

ok boot mirror

but it is stating can't open boot device.

Thanks in advance
