    Creating Adapters with the HMC Enhanced GUI

    I was recently playing around with the enhanced HMC GUI, using the new interface to look at an old test machine.
    The test box had crash and burn LPARs that had been created over time. In some cases, I'd spin up a test LPAR and select the VIO server option that allowed for any client partition to connect to the virtual adapter I'd created. This was to allow greater flexibility going forward -- it wouldn't be necessary to  re-create the adapter; I'd just assign another client LPAR to the existing one. If I hadn't yet built the client LPAR definitions, I'd set up a bunch of server adapters ahead of time for later use with the crash and burn client LPARs.

    The pdump Script

    Do you have a hung process on your AIX machine? Do you need more information about a running process? These are just two instances where the pdump script could help you.
    The pdump script extracts information from the running process by using the kdb command and other AIX tools. This script can be especially helpful if you suspect the process is in a hung state or is suspected to be in an infinite loop.

    A Tool for SAN Troubleshooting

    Are you looking for more information about your SAN? Do you want to learn about the LUNs that have been presented to your host? Maybe you want to be able to compare what your machine sees now as opposed to what it was seeing on the SAN.

    A Message Worth Repeating

    I needed a bigger vehicle. Given my work with Boy Scouts, I spend considerable time on the road, hauling boys and their camping gear.

    I wanted something big enough to comfortably contain eight or nine people and capably transport a trailer of supplies. I also wanted something that was reliable, well-maintained and a good value. I knew it'd take some time. Decently priced used vehicles like that don't become available every day, and they typically sell within hours of being advertised. But after a few months of searching craigslist, I found a Chevy Suburban that fit my needs and requirements.

    A Look at HMC 8.2 (and Beyond)

    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.
