PowerHA: lssrc and clinfoES

cggibbo 270000TMUJ | | Visits (24640)

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       cluster          2883628      active...

VLAN tagging and the VIOS: some questions and answers.

Here are some questions I received recently regarding VLAN tagging on the VIO server. My answers are shown in green .   “Hi Chris,   Q: I’m trying to understand when, where and why there would be the need to use ‘mkvdev –vlan (etc.) on the VIOS, and I’m wondering whether you would be able to clarify this for me, please.   Is it necessary to add the VLAN tag devices to the SEA, or is it suffice to just have them defined within the Virtual Ethernet itself which is part of the SEA?”   A: It is suffice to simply define the VLAN ids assigned...

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 greater than 8 characters then you must enable one of the supplied Loadable Password Algorithms (LPAs). The following table lists the available algorithms and the limitations of each:     For example, to enable the MD5 algorithm I can modify /etc/security/login.cfg file with the chsec command as follows:   # chsec -f /etc/security/login.cfg -s usw -a pwd_algorithm=smd5   # tail -2 /etc/security/login.cfg         ...

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]

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 It has been replaced by Distributed Systems Managment (DSM).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*   Fileset                       Level   State   Type... [More]
