It’s no secret that I like NIM. I’ve written about NIM on several occasions, in Redbooks, technical articles and on my blog. It’s a great tool for installing and maintaining AIX. Occasionally though, it can throw you an unusual error or two when things go wrong. For the uninitiated resolving these errors can be challenging.   Here’s a couple of NIM related questions I received recently. Both are troubleshooting queries.   “I'm getting the following error when trying to create a NIM lpp_source for AIX 6.1” :  ... [More]

  I’ve been working with a customer recently on an issue with nimadm . They were attempting to migrate a system from AIX 5.3 to 7.1 using nimadm . The NIM client AIX level was 5.3 TL12 SP4 and the NIM master was running AIX 7.1 TL1 SP1.   lpar1 : / # oslevel -s 5300-12-04-1119   root@nim1 : / # oslevel -s 7100-01-01-1141   They were running the following nimadm command:   # nimadm -j nimadmvg -c lpar1 -s spotaix710101 -l lpp_sourceaix710101 -d hdisk1 -Y   The nimadm operation would always fail at phase 11:  ...

Using PowerSC RTC to monitor for the deletion of a specific file.   One of my customers was concerned that someone or something was randomly deleting the /etc/niminfo on several of his AIX hosts. We discussed several ways in which he could track down who or what was removing this file. Obviously, the AIX audit subsystem would be an ideal method of capturing this event. However, PowerSC Real Time Compliance (RTC) can also monitor and capture this type of event.   “The PowerSC™ Real Time Compliance feature continuously... [More]

Do you use SSL with nimsh on AIX? No? Well, you might want to consider it. If you regularly use LPM to migrate AIX partitions from one server to another, you may have found that, on occasion , your NIM master has trouble communicating with its NIM clients afterwards. This is by design, as nimsh uses the NIM clients cpuid to authenticate with the NIM master. During an LPM operation, the cpuid of the NIM client changes and its possible the NIM master may reject the client as a result. This problem can occur even when CPU validation is disabled on...

This little tip was passed on to me by a friendly IBM hardware engineer many years ago.   When entering a capacity on demand (CoD) code into a Power system, you can tell how many processors and how much memory will be activated, just by looking at the code you’ve given by IBM.   For example, the following codes, when entered for the appropriate Power system, will enable 4 processors (POD) and 64GB of memory (MOD). I can also tell* that once the VET code is entered, this system will be licensed for PowerVM Enterprise Edition (2C28).  ... [More]
