Question about multi-boot on RS/6000

[Tim Alsop]

I have an RS/6000 and have installed two different versions of AIX on
separate physical disks. I can boot the machine into each o/s by using
multiboot and this is working ok.

What I am trying to find out is, whether there is a way to remotely log onto
the RS/6000 and somehow configure it to boot into the other operating system
version when I instruct it to shutdown. I wondered if there was a
program/command that allowed me to tell the bios which operating system to
boot from ?

Tim.

The bootlist command is your friend. Use it reset the list of potential boot
devices in the firmware. The following command sets the list for both modes
to try hdisk0, then hdisk1, then rmt0, and finally cd0 if all else fails.
bootlist -m both hdisk0 hdisk1 rmt0 cd0

Andy,

Many thanks. It worked. I was hoping it was going to be this easy. I
appreciate your help.
