NIM - "...the resource is currently allocated for client use" - er, NO it's not!
On the odd occasion, NIM may report that a resource is allocated to a NIM client, when, in fact, it is not. Typically, you’d check that the resource was, in fact, not allocated for use to any NIM client and if it was, you would reset the client; and this would resolve the issue. But if that doesn’t work, you may need to take an additional action to resolve the problem. This doesn’t happen very often but it can frustrate you when it does. Here’s an example of the problem. I try to remove an lpp_source resource but... [More]

Minimum memory requirement for AIX 7.2 Live Update

You can check your Minimum Memory setting in your LPARs profile by running the lparstat command (as shown below). # lparstat -i | grep Memory Online Memory : 4096 MB Maximum Memory ... [More]

Does AIX support passwords longer than 8 characters? Yes!
Prior to AIX 5.3 TL7 and AIX 6.1,
there was an 8 character limit on AIX user passwords. If you need passwords of

Password Algorithms (LPAs). The following table lists the available algorithms
and the limitations of each: For example, to enable the MD5 algorithm

More NIM troubleshooting....some basics...
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]
