People are always asking me how often they should be performing PTF maintenance, and when is the right time to upgrade their operating system. Let’s look at PTFs. First, PTFs are Program Temporary Fixes that are created by IBM to fix a problem that has occurred or to possibly prevent a problem from occurring. In addition, sometimes PTFs add new functionality, security, or improve performance. Therefore, I am always dumbfounded as to why customers do not perform PTF maintenance on their machine at least quarterly. If IBM has come out

Last month, I talked about the importance of the HMC and how it shouldn’t be ignored. That leads to the question: How do I keep it running smoothly? The full answer can be pretty complex. In fact, Pete regularly speaks at conferences on the topic of HMC maintenance and the presentation can easily fill a 90-minute session. Today, I’d like to set our sights a bit lower and just talk about the basics of HMC updates. IBM regularly releases Service Packs and PTFs for each version of the HMC software

The Hardware Management Console (HMC) is a strange beast. Anyone with a partitioned system needs one, and it can be an indispensable tool for anyone whose desk isn’t within 100 yards of the machine room…but it isn’t part of the system itself and it usually isn’t critical to everyday operations once things are up and running. Is it part of your critical path or is it an accessory largely to be forgotten? To answer that question, let’s examine how the HMC relates to your system and how IBM supports the

Last month, I talked about how you can make sure your system has the ability to report problems back to IBM in the event of a failure. That functionality can be invaluable for keeping your system running, but what happens if something goes wrong while the OS is still trying to start? What if something fails so far down the hardware stack that the system simply can’t be aware of it before the whole show grinds to a halt? That’s where an HMC has your back, and it can call

We recently had a customer with a power outage and the HMC and AS400 went down hard.  When the power was restored the AS400 was ready to come up, but the HMC had a hard drive crash. If your HMC is set up right you can just push the button on the AS400 and it should start up.  But this time it wouldn’t power on, the reason was the HMC “Power-On Parameter” policy was set to, User-Initiated.  This needs to be set to Auto Start – Always for this option
