Lpar netboot

From Linux on Power wiki

On the HMC lpar_netboot command allows you to collect Mac-Addresses and initiate a network boot without going to SMS or OpenFirmware screens.

Contents 1 Get Mac Address 2 Initiate netboot 2.1 Directed bootp request (for bootp server) 2.2 Broadcast bootp request (for DHCP)

Get Mac Address

1. Lpar-Name -> op720-1-Client3-Debian-3.1
2. Profile-Name -> normal
3. Machine Name -> op720-1

(if you are not sure about the Machine and LPAR name, runs "lsyscfg -r sys" command to get machine name and "lssyscfg -m MACHINE-NAME -r lpar" to get LPAR and profile names.

• Attention: this command will immediately shutdown your partition !
• Make sure you have closed all vterm connections to the partition

hscroot@hmc-op:~> lpar_netboot -M -n -t ent "op720-1-Client3-Debian-3.1" "normal" "op720-1"

Directed bootp request (for bootp server)

-S Serveradress (AIX running bootp): 9.156.175.8 -G Gateway -C Client IP

lpar_netboot -t ent -m bad3f0005002 -s auto -d auto -S 9.156.175.8 -G 9.156.175.1 -C 9.156.175.247 "op720-1-Client3-Debian-3.1" "normal" "op720-1"
# Connecting to op720-1-Client3-Debian-3.1
# Connected
# Checking for power off.
# Power off complete.
# Power on op720-1-Client3-Debian-3.1 to Open Firmware.
# Power on complete.
# Network booting install adapter.
# bootp sent over network.
# Network boot proceeding, lpar_netboot is exiting.
# Finished.

Broadcast bootp request (for DHCP)

If you are installing from DHCP server make a broadcast request:

hscroot@hmc-op:~> lpar_netboot -t ent -m bad3f0005002 -s auto -d auto "op720-1-Client3-Debian-3.1" "normal" "op720-1-SN100486A"
# Connecting to op720-1-Client3-Debian-3.1
# Connected
# Checking for power off. 
# Power off the node
# Wait for power off.
# Power off complete.
# Power on op720-1-Client3-Debian-3.1 to Open Firmware.
# Power on complete.
# Network booting install adapter.
# bootp sent over network.

You can see installation starting in vterm, but be patient, do not open vterm session before the lpar_netboot command returns.

mkvterm -m "op720-1-SN100486A" -p op720-1-Client3-Debian-3.1
