Depends on setup.  Frequently 'getmacs <nodename>' in a blade environment will suffice.

If you have a dynamic ip range, then booting the node should work to re-discover.

Subject: [xcat-user] Node MAC Address Issue

Hi,

 

We have a cluster here comprising of 98 IBM Blades all running CentOS.

 

We recently had a problem with one blade which died and so we have the system board replaced.

 

This however has changed the MAC Address and now it cannot communicate with the rest of the cluster and the head node cannot find it.

 

Any suggestions?

 

Regards,

Lawrence
