3. Distribute the golden image or individual files to the client nodes. See “Propagating the
Golden Image to All Nodes” (page 149).
11.2 Installing and Distributing Software Patches
The following is a generic procedure for installing software patches:
1. Log in as superuser (root) on the head node.
2. Use the rpm command to install the software package on the head node:
# rpm -Uvh package.rpm
The name of the software package usually contains a revision number and a designator for
the hardware platform: either x86_64 for the CP3000 and CP4000 systems or ia64 for the
CP6000 systems.
3. Use the updateimage command to update the golden image:
# updateimage --gc `nodename` --no-netboot
4. Use the setnode command to set up all the nodes to reimage:
# setnode --resync --all
NOTE: If you need to reimage only a subset of the nodes, specify those nodes (as a nodelist
parameter) in the setnode command. For example:
# setnode --resync n[1-7]
5. If your system has been configured for improved availability, enter the
transfer_from_avail command:
# transfer_from_avail
6. Enter the stopsys command to shut down the HP XC system. If necessary, you can specify
a delay (in minutes) with the --delay option:
# stopsys --delay 5
7. Restart the HP XC system nodes. Specify the --image_and_boot option so that the nodes
are imaged before booting.
# startsys --image_and_boot
8. If your system has been configured for improved availability and the nodes that provide
availability have been reimaged, enter the transfer_to_avail command:
# transfer_to_avail
System patch updates can be either simple or complex, depending on the RPMs to be updated.
Simple patch update A simple patch update does not require you to run the
cluster_config utility.
Some simple patch updates require that you reboot the head
node. Many do not. You are advised accordingly in the
instructions for the individual patch.
Complex patch update A complex patch update requires you to run the
cluster_config utility.
A complex patch update usually requires that you reboot the
head node.
11.3 Adding Software or Modifying Files on the Golden Client
The first step in managing software changes to your HP XC system is to update the golden client
node. This can involve adding new software packages, adding a new user, or modifying a
