HP XC System Software Installation Guide Version 3.0

The network boot option label for node n5 is set to eth1boot. This value must be
named Netboot for the setnode command to operate properly.
b. Do one of the following:
• If all boot labels are consistently named Netboot, there is no need to change anything.
Proceed to step 4.
• If the boot label names for all nodes are not consistently named Netboot, complete step 3c
through step 3e to change the label for all nodes that do not have the label Netboot.
c. Enter a command similar to the following to remove the inconsistent or incorrect boot labels. The
following command removes the boot entries for Boot0001 on nodes n4 and n5:
# cexec -w n[4,5] "efibootmgr -b 1 -B"
In the previous command line, -b 1 represents the Boot0001 output line. If you are changing
the Boot0002 output line, specify -b 2 instead.
d. Create new boot labels for nodes n4 and n5 with the value Netboot:
# cexec -w n[4,5] "efibootmgr -c -i eth1 -H 222f0 -U 100 -L Netboot"
e. Verify that the label for all nodes has been set to Netboot:
# cexec -a -f 1 "efibootmgr"
n1: BootCurrent: 0000
n1: BootOrder: 0000,0001
n1: Boot0000* Linux
n1: Boot0001* Netboot <---
n4: BootCurrent: 0000
n4: BootOrder: 0000,0001
n4: Boot0000* Linux
n4: Boot0001* Netboot <---
n5: BootCurrent: 0000
n5: BootOrder: 0000,0001
n5: Boot0000* Linux
n5: Boot0001* Netboot <---
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. Cycle 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.
6. Reset the job state on nodes n1 through n5:
# scontrol update NodeName=n[1-5] State=IDLE
