Once the system has come up, you will have to mount the following file systems: /usr, /var, /var/tmp, /opt and /tmp. You will also have to fsck them.

# TERM=vt100
# export TERM

Find out which file systems need to be mounted:

# cat /etc/fstab

Mount the relevant file systems:

# mount /dev/vg00/lvol7 /usr
UX:vxfs mount: ERROR: V-3-21268: /dev/vg00/lvol7 is corrupted. needs checking

# fsck /dev/vg00/lvol7
log replay in progress
replay complete - marking super-block as CLEAN

# mount /dev/vg00/lvol7 /usr
 
# mount /dev/vg00/lvol9 /var
UX:vxfs mount: ERROR: V-3-21268: /dev/vg00/lvol9 is corrupted. needs checking

# fsck /dev/vg00/lvol9
log replay in progress
replay complete - marking super-block as CLEAN

# mount /dev/vg00/lvol9 /var
 
# mount /dev/vg00/lvol11 /var/tmp
UX:vxfs mount: ERROR: V-3-21268: /dev/vg00/lvol9 is corrupted. needs checking

# fsck /dev/vg00/lvol11
log replay in progress
replay complete - marking super-block as CLEAN

# mount /dev/vg00/lvol11 /var/tmp

Repeat with /opt and /tmp

Remove root password:

# cd /tcb/files/auth/r
# vi root

Remove the line beginning with :u_pwd
Save the file and exit

# passwd root

Type your chosen password. Make sure there is a numeric character.

Reboot the system:

# shutdown -r

NOTE: if your system isn’t a Trusted Computer Base system, there won’t be a /tcb directory. Therefore, you will have to:

# vi /etc/passwd

Remove the password field from the root entry and save the file.

Reboot the system:

# shutdown -r

When the system comes back up:

# passwd root

Type your chosen password. Make sure there is a numeric character.
