When you upgrade your HMC to Version 8.2, there's a new "tech preview" option that's intended to give you a feel for the direction that the HMC interface is heading. One of the big complaints heard from those new to POWER hardware and VIOS is how complicated it can all be to learn. I'm seeing a real effort being made to add greater functionality to the GUI so non-legacy POWER users can more easily adopt the platform.

Lately I've been reading about Docker, and it seems to keep coming up everywhere I look. If you haven't heard of it, it's an "open platform for developers and sysadmins to build, ship, and run distributed applications."

Recently after upgrading to 8.8.2 SP1, I found my HMC was unable to communicate via RMC to my client LPARs.

In environments with machines containing many volume groups and filesystems, we want easy ways of manipulating that information. There's always a need to know to know which filesystem is in which volume group. If you want to grow the size of a filesystem, you are going to want to know which volume group it is in so that you will be able to check if that volume group has free space available in it or not.

If you're new to IBM Power Systems, you're new to upgrading the HMC. Furthermore, you're new to system firmware updates.

Recently a customer rebooted some systems that hadn't been restarted in more than a year. All of the LPARs and the VIO servers were powered off so maintenance could be performed. The customer was able to use live partition mobility to relocate the important LPARs. That left just the dev and test environments.

On April 28, IBM announced
new capabilities for existing POWER8 servers. Today, it’s announcing a new POWER8 server model.

As I've mentioned, I follow several AIX and IBM Power Systems pros on Twitter.
Benoit Creau (@chmod666 on Twitter) is someone you should follow as well. He's been working on a new tool called lssea that "lists information and details about PowerVM shared Ethernet adapters.”

After upgrading an AIX system, a customer found that they needed to back out of the change. They ended up restoring rootvg from an mksysb.
Although that's one way to do it, I don't recommend it. Of course you should have an mksysb around in case of a disaster, but you should also have a local alt disk copy available. This is true for any type of upgrade, but it's especially critical for both VIO server and regular AIX upgrades.

In December I wrote about a document that covers HMC simplification. Actually, the doc isn't just about that. It's also about how IBM is trying to make managing PowerVM easier for customers.
