People Always Make the Difference

Edit: Still one of my favorite places to visit. Originally posted April 9, 2013 on AIXchange I recently wrote about visiting customer locations. I didn’t mention it then, but one visit really stands out. I had no problem finding the place, and there was nothing awe-inspiring about the physical environment. What I’ll always remember is how I … Continue reading “People Always Make the Difference”

The Case for Patching

Edit: Still important to consider. Originally posted February 19, 2013 on AIXchange Do you update your systems? Do you patch your machines monthly? Quarterly? Annually? Do you ever patch? Are change windows built into your environment (e.g., there’s scheduled system maintenance, say, the third Sunday of each month)?

Running cldump on a Cluster

Edit: Hopefully nobody runs into this error these days. Originally posted November 6, 2012 on AIXchange I was recently asked why the cldump command wasn’t running on a PowerHA 7.1 cluster.
