How to Install Ubuntu Xenial 16.04 LTS on Power9 Machines

If you want to install Original LTS Ubuntu 16.04 (with initial LTS Kernel 4.4) on Power9, you were / are out of luck. This is because full kernel support for Power9 got in from 4.10 on wards.

But to some jubilation, 16.04.3 LTS got released today (08/03/17) with support for 17.04 Kernel (4.10). So work around to install Ubuntu LTS on Power9 is to use 16.04.03 LTS HWE kernel / initrd instead of ones I indicated in my previous blog post:



Again, Follow the same procedure in previous blog post  BUT with NEW kernel / initrd links.

Enjoy the first LTS port on Power9

How to setup Megaraid Volume in Petitboot using Storcli

If this is your first time bringing up a OpenPOWER server and you wanted a to setup a megaRAID volume before you do an install: You should be reading this.

In order to  do this

  1. Power on the server and wait for Petitboot menu to show on your VGA or Out of Band console. This should take 4-5 mins .
  2. When should get to Petitboot menu and then press “Exit to Shell” option as show below:

3. Once in petitboot shell, you can access a plugged in thumb drive with storcli64 binary or scp / wget the same binary from Petitboot shell. I am providing the binary corresponding to latest here:

4.  change ‘storcli64’ permissions :   “chmod 777 storcli64”

5.  Now you can use this storcli64 binary to create a VD that you can subsequently install. Here is a dictionary of Storcli commands you can use for doing the same:

Show all physical drives:

./storcli64 /c0 /eall /sall show

Show existing VD

 ./storcli64 /c0 /vall show

Delete ALL Existing VD

./storcli64 /c0 /vall del force

Configure: Add everything to RAID 0 ( Based on number of drives you have, command changes, in my case it was 14 drives)

 ./storcli64 /c0 add vd type=r0 drives=0:0-14

Show new VD

 ./storcli64 /c0 /vall show


 ./storcli64 /c0 /vall start init

Check if everything is online:

./storcli64 /c0 /eall /sall show

How to set openBMC to use static address

Good number of openPOWER servers run openBMC. OpenBMC as of today does NOT support network IPMI but it does support host-BMC IPMI. We can use this to set static IP on BMC using standard IPMI tool commands

Set openBMC to static IP from Host / Petitboot:

To set the BMC running openBMC to static address, run following ipmitool commands from petitboot / host.

   ipmitool lan set 1 ipsrc static

   ipmitool lan set 1 ipaddr 10.127.xx.xx

   ipmitool lan set 1 netmask

   ipmitool lan set 1 defgw ipaddr 10.127.xx.xx

   ipmitool raw 0x06 0x40

You can print lan credentials using:

ipmitool lan print

Remember default credentials of BMC is    root   and 0penBmc

Set openBMC to get static IP from openBMC linux shell:

You can use standard linux “ip” command to set the IP address to static

To check interfaces
ip a
To force eth0 down
ip link set eth0 down
To force eth0 up
ip link set eth0 up
To set static ip
ip addr add dev eth0
To set up routing:
ip route add via dev eth0

How to set OpenPOWER server to boot from any device

OpenPOWER servers have Petitboot bootloader to manage the bootup options / preferences.

Since petitboot is relatively new I am putting together this guide to help walk through on how to set up devices to boot from any device (network or disk).

Step 1. 

Power on the server and wait for Petitboot to come up via the VGA console (or OOB)

Step 2:

Select and click “system configuration” using the key-board arrows and enter key.

Setup 3:

You will find below menu to customize the boot up options. In order to boot from any device, select and press enter on ” Clear and boot Any” option as below

Setup 4:

Once you finish step 3, you will see that Boot Order in the first line of the screen short below changes to “(0) Any Device”

Step 5:

Now let’s save this boot config. For saving the boot order we have to go all the way down to the boot menu with down arrow key and select and press enter on “OK”

Step 6:

At this point you will be returned to petitboot menu and you have successfully set to boot from any device. From your next power on your server will automatically boot into an image that it finds first.

Power-off, Unrack and rack your server (or hard reboot) to test that “boot from any device” preference is working. When you un-rack and re-rack your server, you will have to wait few minutes (for BMC orange light to go off) before you press the host power on button.
