IBM Power Linux Cluster Fence device on Power8 Platform

UNIX AIX

wasn't quite sure which forum to post in.
What typical fence device to configure for a Power Linux PaceMaker Cluster running on the Power8 Platform (S822 Model of hardware), or what should be ordered with the S822 for use as a Fence Device?

The fence agent would have to use the HMC for power systems. I don't see an HMC fence agent for CentOS. If you are using and paying for RHEL subscriptions, maybe you can open a ticket with Red Hat for them to add one upstream?

The fence agents are in the main channel of RHEL/Centos systems. You should be able to use the following command to list the available agents. You could use a similar apt-get command for other linux distro's.

yum list 'fence-agents-*'

Here is a list of all of the packages the base channel for CentOS7 for PPC64.

Thanks again. I am trying to get IBM developer support to tell me what cluster addon they support and recommend with PowerLinux, but they keep dancing around the question. So I will not be using Linux/PowerLinux on any IBM power Servers we integrate on. Have to choke down AIX/PowerHA.

What you could pursue - is IBM (pre-)sales - as you may or may not have your Linux support via IBM.

Developers are probably not the correct "venue" as, afaik, IBM is not really "developing" on Linux - as IBM. There are IBMers who work on OpenSource projects - but those people are not who I would label "developer" in the same sense I would an AIX developer.

That said - if you found someone who said they are an IBM Linux on Power developer - I'll eat my words.

In short - they key part of your question/comment for me was "does IBM support"? For that question I would be in touch with IBM support, not developers.

Hope this helps!

That is the real problem with Linux for Power. The Operating system works great, but none of the extra stuff tends to work and not many third parties make agents for it for their products.

Thank you all for your comments. I guess its the AIX road for me until IBM officially supports Linux and add-ons from a IBM Paid Service and Support view.
