system name and node name differ

shashi kanth — Tue, 10 Jun 2008 06:17:10 GMT

In one of my HP-UX 11.23 IA box, I am facing one error, if i configure any subsystem through "SAM", i am getting an error "The system name and nodename differ. The suggested value is listed bellow. If the suggested value is okay, press the OK button to reset".

Even if i press the OK button,it still throws the same error again and again whenever i invoke SAM.

The hostname in /etc/hosts & /etc/rc.config.d/netconf is same.

Anyone tell me how to solve this issue ?

where we can specify node name ? in which file ?

In the /etc/rc.log file, i can see the bellow message.

Setting hostname
Output from "/sbin/rc1.d/S320hostname start":
----------------------------
Nodename must be less than 9 characters
EXIT CODE: 1
"/sbin/rc1.d/S320hostname start" FAILED

How to overcome this limitation ? Do i need to apply some patch ?

Historically, the node/hostname is limited to 8-characters and 64-characters respectively. See the manpages for 'hostname' for more information.

With 11.23, there is a new product which enables long (255) names for both:

I am going to set-up VCS5 in this box,one of the box is giving this trouble. Is it okay if nodename and hostname differ from the application point-of-view? Or, nodename must be equal to hostname ?

If i install this product, does this will effect on my VCS ?

Any suggestions ?

thats it, your hostname has 9 characters.
by default HP-UX allows only 8-characters hostname. if you don't have NodeHostNameXpnd in your machine, you will face such problem.
