Even if support ended for AIX 5.3 since April 2012, some companies still have old AIX releases like 5.2 or even older. I had some migrations to do for one of my customers on standalone P5 and blades, everything went well but I saw filesystems mount error messages at boot. Once logged in, I saw all my volume groups but few of them were inactive, and a varyonvg gave error messages.
Recently, I was installing a POWER7 P770 for one of my customers. But instead of installing VIO servers from scratch, we made clones on the storage subsystem (HP 3PAR)Â from VIOS previously installed on another P770. In one hand, it had the benefit of being a fast method avoiding us to install and configure the Operating Systems, 3PAR multipathing drivers, customer tools; but in the other hand, we have to correct some settings and do some clean-up operations (hostname, devicesâ€¦).
My customer often uses this method to clone LPAR (AIX/VIO) and as expected DLPAR operations wonâ€™t work. Even if my customer usually knows how to correct that, this time had been more tricky because of CAA (Cluster Aware AIX, from AIX 6.1 TL6 & 7.1).
Since I reinstall my laptop with Windows 7 64 bits and all my tools (because of a memory upgrade), I had the “good” idea to install Office 2010 Suite in 64 bits version too !
Unfortunately, Nmon Analyser don’t work under Excel 2010 64 bits. I tried to figure it out by changing some function declaration and comenting some calls and I finally get to have it working. I think it is doing the work and it can help few people but I’m not a VBA expert, so let me know if there are some issues.
Today, I passed and validated my first certification test : AIX 6.1 Administration (000-104).
Now, I have a new status : IBM Certified System Administrator – AIX 6.1
This test is a MCQ of 117 questions with a time limit of 150 minutes, Â the following lines list the objectives :
Backup and Recovery (5%)
Recover from a lost root password
Backup AIX OS and data using AIX commands (mksysb, mkcd, tar, backup, etc)
Restore AIX OS and data using AIX commands, including listing backup media contents (restvg, restore, tar, etc)
This my first post and I’m going to blog about WPAR technologyÂ
What is a WPAR ? Â WPAR = Workload PARtition.
It is a software virtualization/partitioning system within an AIX instance which allows isolating execution environment, as share and resources control allocation (cpu, ram, network) in order to limit interactions between others WPAR, and AIX hosting operating system.
