Hi Satish,

You can do it by booting the system and interrupt boot to modify your alternate boot path.

It's a PROM modification in ISL level.

Hi Satish
Use setboot command to change paths wit out rebooting machine.

#setboot -p to set primary path
#setboot -a to set alt. boot path.

While reboot interupt the boot sequence and change the same. Menus I guess are slightly different on K and N boxes. Extact commands don't remember now.

Interrupt the boot process and use the "path" command to set the primary and alternate boot path.

path pri
path alt

With HPUX booted you can use the setboot(1m) command to set the path.

Hi Satish:

If you want, after the fact, to find out from where you booted, do:

# echo boot_string/S|adb /stand/vmunix /dev/mem
