Vinod, you can query the running kernel:

echo "boot_string/s" | adb /stand/vmunix /dev/mem

Hope this helps you,

How do I identify the disk which server booted from
on a mirror root disk .

Ex: I have 2 disks in vg00 , /dev/dsk/c0t6d0 and
c4t6d0 .

Say if I boot the server manually from HA path ( ie
c4t6d0 ) , after server comes to munti usermode , how
to confirm the disk it booted is from c4t6d0 .

The reason I am curius about this is on IA , disk HW
path on EFI are different ( like Pnu5,Lun6 ... ) .

Thanks
-vinod
