Which disk server got booted ?

Madeswaran N
To find out the disk from which the server got booted, we need to use below command 

#ll  /dev/disk | grep $(echo "bootdev/x"|adb /stand/vmunix /dev/kmem | awk '/0x/ {print substr($1,5)}')

examble : 
root:server1# ll /dev/disk | grep $(echo "bootdev/x"|adb /stand/vmunix /dev/kmem | awk '/0x/ {print substr($1,5)}')
