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. Prepare all client nodes to network boot rather than boot from local disk:
# setnode --resync --all
4. Turn on and turn off power to the specified nodes to automatically start the reimaging
operation:
# stopsys n[1-5]
# startsys --image_and_boot n[1-5]
All nodes reboot automatically when the installation is finished.
5. Run the transfer_to_avail command to shut down all HP XC services and IP aliases
that will be managed by an availability tool. After shutting down these services and IP
aliases, the transfer_to_avail command starts each availability tool. Then, the availability
tool starts up the services and IP aliases it is managing.
6. Reset the job state on nodes n1 through n5:
# scontrol update NodeName=n[1-5] State=IDLE
