14.8 Changing Administrative Passwords
This section describes the procedures for changing the following administrative passwords on
an HP XC system:
• “Changing the Superuser Password” (page 162)
• “Changing the CMDB Password” (page 163)
• “Changing the Interconnect Password” (page 163)
• “Changing the Console Port Password” (page 165)
• “Changing the Nagios Administrator Password” (page 166)
• “Changing the LSF Administrator Password” (page 166)
14.8.1 Changing the Superuser Password
The following procedure describes how to change the root password and propagate that change
throughout the HP XC system:
1. Log in as superuser on the head node.
2. Use the passwd command to change the password locally on the head node.
At this time, the root password is changed only on the head node.
3. Update the golden image to ensure that the root 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 146).
