Netboot the live server installer on IBM Power (ppc64el) with Petitboot
Note:
This documentation has moved to a new home! Please update your bookmarks to the new URL for the up-to-date version of this page.
Open a terminal window on your workstation and make sure the ‘ipmitool’ package is installed.
Verify if you can reach the BMC of the IBM Power system via ipmitool with a simple ipmitool call like:
$ ipmitool -I lanplus -H Power9Box -U <user> -P <password> power status
Chassis Power is off
or:
$ ipmitool -I lanplus -H Power9Box -U <user> -P <password> fru print 47

Activate serial-over-LAN
Open a second terminal and activate serial-over-LAN (SOL), so that you have two terminal windows open:
- to control the BMC via IPMI
- for the serial-over-LAN console
Activate serial-over-LAN:
$ ipmitool -I lanplus -H Power9Box -U <user> -P <password> sol activate
...
Power the system on in the ‘control terminal’ and watch the SOL console:
$ ipmitool -I lanplus -H Power9Box -U <user> -P <password> power on
...
It takes some time to see the first lines in the SOL console:
[SOL Session operational. Use ~? for help]

After a moment the system reaches the Petitboot screen:

*Exit to shell
─────────────────────────────────────────────────
Enter=accept, e=edit, n=new, x=exit, l=language, g=log, h=help
Select “*Exit to shell”.
Note:
Make sure you really watch the SOL, since the Petitboot screen (above) has a time out (usually 10 or 30 seconds) and afterwards it automatically proceeds and tries to boot from the configured devices (usually disk). This can be prevented by just navigating in Petitboot.
The petitboot shell is small Linux based OS:... Exiting petitboot. Type 'exit' to return. You may run 'pb-sos' to gather diagnostic data
Note:
In case one needs to gather system details and diagnostic data for IBM support, this can be done here by running ‘pb-sos’ (seemsg).
Download the ISO
Now download the ‘live-server’ ISO image (notice that ‘focal-live-server-ppc64el.iso’ uses the liver server installer, Subiquity, while ‘focal-server-s390x.iso’ uses d-i).
Again, for certain web locations a proxy needs to be used:
/ # export http_proxy=http://squid.proxy:3128 # in case a proxy is required
/ #
/ # wget http://cdimage.myasnchisdf.eu.org/ubuntu-server/daily-live/current/focal-live-server-ppc64el.iso
Connecting to <proxy-ip>:3128 (<proxy-ip>:3128)
focal-live-server-pp 100% |....................| 922M 0:00:00 ETA
Next we need to loop-back mount the ISO:
/ # mkdir iso
/ # mount -o loop focal-live-server-ppc64el.iso iso
Or, in case autodetect of type iso9660 is not supported or not working, you should explicitly specify the ‘iso9660’ type:
/ # mount -t iso9660 -o loop focal-live-server-ppc64el.iso iso
Now load kernel and initrd from the loop-back mount, specify any needed kernel parameters and get it going:
/ # kexec -l ./iso/casper/vmlinux --initrd=./iso/casper/initrd.gz --append="ip=dhcp url=http://cdimage.myasnchisdf.eu.org/ubuntu-server/daily-live/current/focal-live-server-ppc64el.iso http_proxy=http://squid.proxy:3128 --- quiet"
/ # kexec -e
The system is going down NOW!
Sent SIGTERM to all processes
Sent SIGKILL to all processes
...
Note:
In order to boot with and install the HWE kernel (if available), substitutevmlinuxwithvmlinux-hwein the firstkexecline.
The system now performs the initial boot of the installer:
