<p class=MsoNormal>Not using heartbeat (Lustre 1.8.4 manual section
8.3?).  As we've added OSS, we've never explicitly placed the machine
names in any configuration.  <br>
<br>
Furthermore, no IP changes will be made, just the DNS name, so perhaps we are
safe after all?<br>

Renaming OSS is easy and don't require any Lustre reconfiguration if your
Lustre configuration is based on IP addresses and not hostnames.<br>
<br>
If you have heartbeat, you need to change names in configuration<br>
