It's a little bit tricky to answer. First, execute setboot without any options. That will identify the primary and alternate boot paths. Normally the primary path is used; however, it is possible the neither was used; the box may have been manually booted.

That is when the method proposed by Jim should be used:

# echo "boot_string/S" | adb /stand/vmunix /dev/mem (or /dev/kmem)

However, there is a "gotcha" there as well in that the box might not have booted from the default "/stand/vmunix". If the adb command above returns NULL or garbaged values then that means that the symbol table in /stand/vmunix does not correspond to the running kernel's memory image in /dev/kmem.
You then have to repeat the command using /stand/vmunix.prev, /stand/vmunix.save, or any other kernel files found in /stand until adb returns meaningful strings.

Hi Sudhaadm,

You can try thist to know , from which disk the system is booted up:

# echo "boot_string/S" | adb64 stand/vmunix /dev/kmem

The output will be like this :
-----------------------------

boot_string:
boot_string: disk(0/0/1/1.0.0.0.0.0.0;0)/stand/vmunix

hth,
Raj.
