4. Prepare all client nodes to network boot rather than boot from local disk:
# setnode --resync --all
Note
If you did not follow the instructions in step 3 to set Netboot as the common network boot label, you
cannot use the setnode command to set all nodes to network boot. You must use the following command
instead:
# setnetboot --all --boot always --string "boot_string"
In the previous command, boot_string represents the user-defined boot string you found by using
efibootmgr command.
5. Shut down all client nodes:
# stopsys
6. Insert the HP XC System Software Version 3.0 DVD distribution media into the DVD drive on the head
node.
7. Reboot the head node to start the Kickstart installation:
# reboot
8. Follow the instructions in this document, beginning with Chapter 3 (page 27), to complete the installation
process.
Reinstalling One or More Nodes
Follow this procedure to prepare one or more Itanium-based client nodes to be automatically reinstalled from
the latest golden image on the image server. This procedure sets the specified nodes to network boot from
the DHCP server and automatically starts a reinstallation operation on the node or nodes by temporarily
modifying the EFI environment to allow the node or nodes to network boot.
This procedure assumes nodes 1 through 5 (n1–5) are to be reinstalled.
1. Begin this procedure as the root user on the head node.
2. Use the scontrol command to ensure that all jobs are drained from nodes n1 through n5:
# scontrol update NodeName=n[1-5] State=DRAIN Reason="system shutdown"
3. Before shutting down the system, ensure that a common network boot label is defined for all nodes in
the EFI environment:
a. Enter the following command to display the network boot label for all nodes:
# cexec -a -f 1 "efibootmgr"

The network boot option label for node n1 is set to Netboot.
2
The network boot option label for node n4 is set to eth1boot. This value must be
named Netboot for the setnode command to operate properly.
