Great article Chris. Do you know if there is a way of selecting the surrogate LPAR IP or does it have to just 'pick from pool'?

cggibbo commented Oct 20 2017 Conversation Permalink

Thanks Stu. AFAIK there's no way to specify an IP address, at the moment. PowerVC just picks from the IP pool.

Great article Chris - additionally - PowerVC 1.4.0 (https://developer.ibm.com/powervc/2017/10/10/announcing-powervc-1-4-0/) allows live capture of systems, so you can patch/update a SOE system Live, then Capture it without shutdown to be deployed as the new GOLD image (if that is the deployment cycle that you use on your site)

Thanks Dom. You can enable live capture using "# powervc-config compute live-capture --enable --host MYHOST --restart".

Couple questions, what is the minimum PowerVC role required for pvcauth user authentication, I'm hoping not Administrator. Can authentication occur via the NovaLink partition over the MGMTSWITCH, or dose the VM need comms to the PowerVC server?

"You can use the pvcauth command......if you have appropriate PowerVC administrative authority."

"Can authentication occur via the NovaLink partition over the MGMTSWITCH....?". ​No. The PowerVC mgmt server might be on a different machine to that of the Novalink partition. This would require network connectivity between the two systems.

Okay so it seems VM Manager + Storage Manager will do the trick.

That's unfortunate, routable comms to the PowerVC server from the VM would add challenges to a IaaS cloud offering.

I believe PowerVC "Administrator" role is required, otherwise you'll receive this message: "1430-175 FAILED: User does not have PowerVC permissions (admin role) for Live Update processing."

You make an excellent point re: IaaS. Please submit an RFE for PowerVC to cater this requirement. Thanks. https://www.ibm.com/developerworks/rfe/

@cggibbo Chris thanks a lot! According to your experience: Could we say that AIX live update is stable enough, that customers can use it unhesitating in a production environment?

cggibbo commented Oct 13 2017 Conversation Permalink

Yes. Of course, customers should thoroughly test Live Update in a non-production BEFORE implementing in production.
