RHEL 7.4 as I’m aware is the only GA’ed enterprise OS on POWER9 and hence Barreleye G2. I’ve seen couple of folks have issues picking the right image / boot arguments while attempting this install , and fail, so wanted to clearly put the steps down here:
If you instead want to install Ubuntu 16.04 LTS on POWER9 I’ve already written instructions for that in previous post:
- First grab the DVD (2.9 GB) from RHEL website. For the purposes of this post we’ll use evaluation version:
> Go to RHEL downloads page:
> Login and Get Download Link “Red Hat Enterprise Linux for Power 9”
NOTE1: DO-NOT get link for generic “RHEL big-endian for ppc64” and “RHEL little-endian ppc64”) rather get specific version of download provided for POWER9
NOTE:2 : Download the expansive DVD ( 2.9GB binary as RHEL calls it ) , just the basic ISO file is NOT enough for netboot, since there is no public mirror for repo / package data, that I’m aware of.
See picture below, get the second file. In my case file name was “rhel-alt-server-7.4-ppc64le-dvd.iso”. If you are missing the alt, you are getting the wrong file:
2. Once you get the download link for this image, wget it to local (apache) http server (obviously, this is different than the POWER machine you are doing the install) and mount that iso to a folder on the http server path
wget <hyperlink to rhel-alt-server-7.4-ppc64le-boot.iso>
mount -o loop rhel-alt-server-7.4-ppc64le-dvd.iso\?_auth_\=1516572534_bc1326574be188a5e87bb59dfcd70b8e rhel9
See picture below for help:
3. Now get to main petitboot menu and add a new boot option by “n” button. Fill in the new boot option menu with following mock links as example :
4. Click save and execute the new boot option you just created “User item 1”:
5. That will boot to RHEL 7.4 Install menu in about 2 minutes or so. Select “Text mode” as I ran into some issues getting VNC install working:
6. You will be greeted with the following text menu screen. The only tricky item here is number 3, “Installation Source”.
Select http mirror and enter the mount location of your iso as the selection:
7. After completing all the necessary options 1 through 9 , press “b” to begin the installation begin the installation.
8.Installation should be done in under 7-8 minutes as we are choosing to install from local mirror:
