Changing the Root Password

Log in as superuser on the head node.

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.

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`

See “Updating the Golden Image” for additional information on updating the golden image.

Run the following commands to update all the appropriate files throughout the HP XC system:

# pdcp -a -x `hostname` /etc/password /etc/password
# 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 root password is changed on all the nodes in the HP XC system.
