AIXpert Blog is about the AIX operating system from IBM running on POWER based machines called Power Systems and software related to it like IBM Systems Director, PowerVM for virtualisation and PowerSC for security plus performance monitoring and nmon
The March 2007 Issue of the IBM Systems Magazine has a workaround that allows you to "dynamically expand rootvg" disks located on mirrored VIO servers. The workaround is needed because the command "chvg -g rootvg" on the client does not pick up the LV size change on the VIO server ("extentlv"). The IBM Systems Magazine is located at http://www.ibmsystemsmag.com/ME2/Default.asp Search for "Dynamically expand rootvg", or the March 2007 issue of the magazine. Expand_RootVG_of_VIO client.pdf

For those in the Western US, there will be a Power on Demand roadshow starting next week. The roadshow is targeted for technical audiences, and will demonstrate the following: Power5 Virtualization Creation of Virtual I/O Servers Creation of micropartitions with virtualized boot disks and ethernet Dynamic CPU load balancing Rapid provisioning of servers By the end of this session, you should be able to set up your own Power5 server with micropartitioning and virtualization. For more information and registration, see the following URL... [More]

On August 8, 2005, President George W. Bush signed the Energy Policy Act of 2005. This Act changed the time change dates in the U.S. Beginning in 2007 AIX development will be releasing APARs to change the current AIX behavior. A workaround will also be published for AIX 4.3 since it is out of service. DAYLIGHT SAVING TIME DEFAULT CHANGING IN 2007 The United States official Daylight Saving Time begin and end dates have changed as of the year 2007.

The AIX 6 open beta is now available from https://www14.software.ibm.com/iwm/web/cc/earlyprograms/ibm/aix6beta/ AIX 6 offers new capabilities such as Workload Partitions, Role Based Access Control and many other exciting features. AIX 6 is fully binary compatible with AIX 5L. AIX 6 will run on IBM systems based on POWER4, PPC970, POWER5 and POWER6. Go to http://www-03.ibm.com/servers/aix/6/preview.html for more details on the AIX 6 preview.
We have the new HMC 8.1 code stream to manage the POWER8 machines. It also manages the POWER6 and POWER7 machines but not POWER5.
I find the HMC Virtual Storage Management panel very useful and saves me time for assigning Shared Storage Pool (SSP) space to virtual machines (VM's) and automatically doing this for Dual VIO Servers without having to log-on to the VIOS servers at all. It is also good for assigning virtual DVDs to VMs to boot and install the various operating systems, AIX, RHEL, SLES, Fedora, Debian, etc.

I need to make it clear that these pictures are from an Early Ship Program machine which might vary a little from the final Generally Available (GA) models from November 2014. For example, missing labels or stickers plus colours of handles and parts etc. The engineering will be much the same.
Our machine is part of the Early Ship Program and we get to run hardware tests before machines are shipped to customers from GA. These test include things we would never expect customer to do -... [More]
