You need to be at the console for the prior post to work.

It would appear however that you have had a hardware failure. Your dump/swap device appears to be offline. That could be a bad disk, cable or controller.

Booting to single user mode will not help much.

In single user mode;

mount /var
mount /usr

Then ioscan -fnC disk

Also, get the cd out of the drive if you are not booting off of it.

Hi,

hpux -lm = maintenance mode

or

you can boot from a recovery cdrom...

or

you can boot from the mirror disk?
