[xcat-user] Making nodes IPs static

Discussion:

Hello all,

I'm taking last steps to take our xCAT installation to production. I'm
working on making the IP addresses static on the hosts.

The DHCP server is assigning IPs as it should, however our management
policy requires that the nodes shall have static IPs after complete
installation.

Does xCAT has a feature for this, or should I write a small script for this.

Also, as far as I can tell, xCAT allows nodes to talk with master's DB
about its details. Is there any documentation for this?

Best regards,

Hakan Bayindir

Hello Hakan,

I can answer your first question:

You can use the xCAT "hardeths" postscript to achieve this.
(It is located in /install/postscripts).

This will make the DHCP assigned IP address static
Add this post script to the xCAT postcripts table for your node/nodegroup definition.

Regards,

David

If your hosts have a single interface, hardeths will do the trick w/o any additional configuration changes. If your nodes have multiple interfaces, you can use "confignics -s" (man confignics) and omit hardeths. To use confignics, you'll need to configure the nics table (man nics)
