Oracle VM 3: Migrating a NAS Server Pool to a Different NFS Server or IP
Last updated on FEBRUARY 24, 2017
Applies to:Oracle VM - Version 3.0.1 to 3.3.1 [Release OVM30 to OVM33]
This document describes how to change the IP address of the NFS file server that is being used to present the pool file system and/or storage repositories to all Oracle VM Servers in a server pool. This solution note is specifically for NFS file servers where an IP address was used instead of hostnames when initially discovering the NFS file servers.
Using hostnames registered in DNS for Oracle VM NFS File Servers and iSCSI SAN Servers is an Oracle VM best practice. Using registered hostnames would have avoided the need for this sort of invasive solution requiring a temporary outage of all running Oracle VM guests. An alternate solution in cases where you don't, or can't use DNS is simply to ensure you create a master /etc/hosts file on your Oracle VM management server and then use it to populate the hosts file on all Oracle VM servers.
