You may need to add rules in ACF2/RACF to get authorithy to do this.

>From "B"
# vmcp link  "A" 100 1100 mr ( assuming 100 is  instance A's root disk )
# chccwdev -e 0.0.1100
# mkdir /Aroot
# lsdasd ( to determine /dev/dasd? )
# mount /dev/dasd?              /Aroot
Then you can either     # cd /Aroot/etc
        Or
                                # chroot /Aroot
                                # cd /etc

After fixing:

# /umount /Aroot
# chccwdev -d 0.0.1100
# vmcp detach 1100

You should be able to bring up "A".

Hope this is what you're looking for.

Subject: Mounting root fs of one instance to another instance to make repairs

Under vm 5.3 both instances are suse sles10.

Some one edited the /etc/inittab on instance A.

How can we mount instance a's root fs to instance b so as to fix the inittab?
Or, is there a better way?

Thanks for any help.
