Late last week Systems Director 6.2 was released - a few days early too!  This is the free to download and use IBM platform management software from IBM. For us AIX guys that means Power Systems Hardware, HMC, IVM, VIOS and AIX - and Linux on POWER too This new release is was focused mainly performance, simpler install (or migration from 6.1) and rolling in many fixes that could not be addresses with service packs.  There are also some new features like dual VIOS SAN support for VMControl virtual application deployment.  AIX is obviously the...

AIX 6.1 TL04 sp3 supports the new POWER7 machines like Power 750, 77 and 780, where CPUs can be run at slower speeds to reduce electrical energy use when not busy. This feature is switched on by Systems Director and the Active Energy Manager plugin which talks to the service processor to enables it.  I like the "Dynamic Power Saving - Favour Performance" option.  From the AIX end, the pmcycles command is used to find your current CPU frequency. Before switching on the energy saving: # pmcycles -M This machine runs at 3550 MHz - This... [More]

Using NIM to install VIOS 2.1 The install may hang with after the message: "Mounting File Systems" Why? VIOS 2.1 requires more than 1GB of memory typical for VIOS 1.5 From the Release Notes: Each LHEA *port* assigned to the VIO Server requires a minimum of 612MB (not a typo) of memory - *each* port. This is in addition to the base memory that VIOS 2.1 itself requires (typically 512MB). Example: If you have two [2] LHEAs assigned to VIOS 2.1, the VIOS will need a minimum of: 612 MB + 612 MB + 512 MB = 1,736MB (LHEA) + (LHEA) + (Base) =... [More]

This is a new feature of starting with AIX 5.3 TL9 and AIX 6.1 TL2. svmon will now report a new metric called "available memory." This is the amount of memory available to applications. It includes memory in the file cache. The basic idea is that a user can consume the "available memory" without causing the system to start paging to paging space. Once "available memory" is depleted, AIX will have to start paging out to paging space. To get svmon to display the available metric, you can specify the ''-O summary=basic" option. There are a...
