We maintain many customer systems here at iTech, and one thing that seems to be consistent now across all of our customer environments is that system IFS (Integrated File System) directories are getting very large.  Many systems that we manage now have IFS root directories containing over 1 million objects! Large IFS root directories present a problem from a save perspective in that they can take an inordinate amount of time to save using normal IFS save commands such as SAV, SAVBRM, and GO SAVE option #21.  On full system

This is documented by IBM and also in one of Pete’s newsletters from a while ago, but I saw it today on two HMCs, so I wanted to deliver this short tip. Before doing a version upgrade on an HMC, make sure that the Machine Type-Model and Serial Number reported in the HMC GUI matches that which is printed on the sticker on the front of the machine. If it does not match, then per IBM do not attempt an upgrade.

Moving files between IBM i systems can sometimes be a cumbersome task, but a feature added to IBM i Access Client Solutions in recent versions allows you to transfer files from a single system to multiple systems.

This feature can be found in the Integrated File System function under General tasks.

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
