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]

PowerHA: lssrc and clinfoES
So you’re configuring
a new PowerHA 6.1 cluster and you
decide to check if the clinfoES subsystem is running. You run the following command: #
lssrc -a | grep cluster clstrmgrES
cluster
2883628 active Hmmm, clinfoES is not listed. To ensure that
is clinfoES is shown in lssrc output, in both inactive and
active states, run the following command on all nodes in the cluster: #
chssys -s clinfoES –d And now clinfoES is shown: #lssrc
-a | grep cluster clstrmgrES

Managing users with dsh and chpasswd - (plus info on DSM and dping).
Starting with AIX 7.1, CSM is no
longer supported or available. It has been replaced by Distributed Systems
Managment (DSM). Section 5.2 of the IBM AIX 7.1 Differences Guide Redbook provides
details of the new DSM capabilities.
Fortunately DSM still provides access
to the dsh command. I’ve written about how I’ve used this utility
in the past . The new dsh command (and other tools) are
provided in the new DSM filesets named dsm.core and dsm.dsh . root@nim# lslpp -L dsm*

Updating your NIM master to AIX 7.1 TL2? Take note!
After
updating my NIM master to AIX 7.1 TL2 SP1 (7100-02-01-1245), I noticed a
problem. Whenever I installed a new AIX partition using NIM, the resources
allocated to the NIM client were not being de-allocated, even though the installation was completing successfully. Also,
if I tried to run my usual ‘NIM client reset’ script (below), the resources
were still allocated. #!/usr/bin/ksh # Reset a
NIM client. if [[
"$1" = "" ]] ; then echo Please specify a NIM client to reset
e.g. aixlpar1. else if lsnim -l $1... [More]

Troubleshooting AIX hdisk configuration errors
Last year I was working for a customer that was upgrading several AIX 5.3 systems to AIX 6.1 . The migrations were successful for the most part, but we did encounter one issue that took a little time to resolve. The customer was using nimadm to migrate. This process worked fine, however, on a couple of systems a strange error was encountered after the migration. The LPAR was booted into AIX 6.1 and everything came up fine. The applications were started and users started accessing the system. It was several days later, when the AIX... [More]

OpenSSH 7.0 & greater disable ssh-dss by default. http://bit.ly/2vZBMyH If you upgrade OpenSSH, to 7.1.102.1100 on AIX for example, you may notice that you're unable to login afterwards, with ssh-dss keys.
