Hostname change

Created: 01 Jun 2005 • Updated: 21 May 2010 | 2 comments

Hi, I have a 2 nodes cluster on AiX (vcs 4.0 MP1, AiX 5.3) and I need to change both the hostnames.
Which is the shortest way to do it? Where can I find any documentation concerning this topic?

Thanks

Andrea

The shortest way is changing OS's hostname only.
First check /etc/VRTSvcs/conf/sysname. If sysname exists and contain VCS node name, VCS may work correctly after changing OS's hostname. VCS node name still remain old name.

If you want to change both OS's hostname and VCS node name as same, following procedure needed.

1. Stop VCS/GAB/LLT
2. Change node name in following files.
/etc/llttab
/etc/llthosts
/etc/VRTSvcs/conf/sysname
/etc/VRTSvcs/conf/config/main.cf
3. Change OS's hostname and reboot.

I hope this helps.
