two commands you can use,

#setboot

OR

#lvlnboot -v

[Tonya Underwood]

# echo 'boot_string/S' | adb -o /stand/vmunix /dev/mem

no need for -o prior to 11.23

bkpsrv#echo 'boot_string/S' | adb -o /stand/vmunix /dev/mem
bkpsrv#uname -a

Just check the beginning of the syslog.log the boot path is listed:

"vmunix: Boot device's HP-UX HW path is: 0/3/0/0/0/0.0.0"

[kuldeep saroha]

echo "boot_string/S" | adb -k /stand/vmunix /dev/kmem


this thing works for me.


Thanks and Regards

The only way to find this out is IMHO to inspect the console logs from the MP.

Do a
lvlnboot -v

You will see something like the following:

Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t2d0 (0/0/1/1.2.0) -- Boot Disk
/dev/dsk/c2t2d0 (0/0/2/0.2.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c1t2d0
/dev/dsk/c2t2d0

Note: the "Boot lvol1 on:" /dev/dsk/c1t2d0 -- This is currently the boot disk. The entry under that is the mirror.
