Change IP and Hostname on Red Hat Linux

Question

Hello, We are going to move two Linux boxes and a VNX5400 to a new datacenter. We need to change the IPs and Hostnames of the two servers. Do I need to do anything to Powerpath? I don't recall Powerpath caring about the hostname, just wanted to be sure. Powerpath 5.6 Red Hat Linux 5.8 Thanks.

to VNX so you don't have to install navi agent.

dynamox · Answer

don't need to do anything with PowerPath (especially 5.6). Newer versions of PowerPath will auto-register the host name in-band. You don't have PowerPath configured to report to a central Powerpath management console ?

No management console yet.  Auto-register the hostname in-band to what?

DanPJ · Answer

Excellent! We don't run naviagent. I can save the step of reregistering the HBAs.
