HP XC System Software Administration Guide Version 3.2.1

1. Log in as superuser (root) on the head node.
2. Use the passwd command to change the password locally on the head node:
# passwd lsfadmin
At this time, the lsfadmin account password is changed only on the head node.
3. Update the golden image to ensure that the lsfadmin password change is propagated the
next time the nodes are reinstalled:
# updateimage --gc `hostname` --no-netboot
For additional information on updating the golden image, see “Updating the Golden Image”
(page 150).
4. Run the following commands to update all the appropriate files throughout the HP XC
system:
# pdcp -a -x `hostname` /etc/passwd /etc/passwd
# pdcp -a -x `hostname` /etc/group /etc/group
# pdcp -a -x `hostname` /etc/shadow /etc/shadow
# pdcp -a -x `hostname` /etc/gshadow /etc/gshadow
When this step is complete, the lsfadmin account password is changed on all the nodes
in the HP XC system.
