I was fighting a problem in AIX where I was trying to make a change to an LPAR via the HMC but the HMC couldnt get to the LPAR to make the change. Here is how I got is working.

First, make sure that the hostname of the LPAR is the same as the name of the LPAR in the HMC… The HMC should be able to use that LPAR name to get to the LPAR via the public network (HMC and LPAR able to chat openly across HMC’s public interface).

on the LPAR, run ‘lsrsrc IBM.ManagementServer’ - you should see a name/addy for the HMCs that it is connected to.

If you get no output or even good output, with root rights, restart the daemon.
‘/usr/sbin/rsct/bin/rmcctrl -z’
‘/usr/sbin/rsct/install/bin/recfgct’
‘/usr/sbin/rsct/bin/rmcctrl -p’

Now, wait a few minutes then run ‘lsrsrc IBM.ManagementServer’ and you should see the connected HMC and the HMC should be able to make config changes to the LPAR now… All fixed.

I love the clicky mouse wheel but was a bit saddened when installing VMWare Tools took it away in my kUbuntu VM. The fix is really pretty easy — as root (via sudo) edit /etc/X11/xorg.conf and change the mouse type from ‘ps/2′ to ‘IMPS/2′ then restart X… The mouse wheel is BACK!

AIX has a ton of features but the coolest feature is just how fast these system run. They absolutely fly. I have spent time on the 4.2GHz models and I can’t imagine what the 4.8GHz will perform like. I hope to run some quantitative tests before long (if HACMP and the VIOs go well) to compare them to our fastest Sun boxes. I love Sun and am even a SCE but they have been laging behind the CPU race. I know all of the arguments about cores vs speed, etc but either way, these P6 boxes are fast.
