I was working at a client site today, on a NIM master that I configured a month or so ago. I was there to install the TSM backup client software on about 30 or so LPARs. Of course I was going to use NIM to accomplish this task.   The software install via NIM worked for the majority of the LPARs but I noticed a few of them were failing. This was very odd, as the last time I’d use the same NIM method to install software, everything was fine.   I suspected that perhaps something had changed on the client LPARs...maybe with their /etc/niminfo...

AIX has a new “critical volume group” capability which will monitor for the loss or failure of a volume group. You can apply this to any volume group, including rootvg. If applied to rootvg, then you can monitor for the loss of the root volume group.   This feature may be useful if your AIX LPAR experiences a loss of SAN connectivity e.g. total loss of access to SAN storage and/or all SAN switches.

A question I received this week from a customer.   Hi Chris,   Is there  a way to find on which processor a process is executing?   If I’ve used binprocessor, ps –emo THREAD, would show which processor a process is bound too. But when that’s not been used, what are the options?   The ps command will only help if we bind a process to a specific CPU. For example, here we can see that the bootpd process has been bound (and then un-bound) on processor 3:   # bindprocessor -q The available processors are:  0 1 2 3   # bindprocessor 8585302 3  ...
