Integrating HA Into Your xVM Ops Center Installation

If you're considering implementing the high-availability (HA) solution in your Sun xVM Ops Center installation, there are a couple of things to keep in mind.

First, it's important to know that the HA solution for Sun xVM Ops Center is based on being able to transfer the /var/opt/sun/xvm directory structure from one system to another. So, the work that you do to create the HA configuration mainly focuses on building a transportable storage solution to hold this directory structure. The big thing to keep in mind is that you need to create this storage solution so that it holds the /var/opt/sun/xvm directory structure on the primary Enterprise Controller before you install the Sun xVM Ops Center software.

Second, there are three LOFS mounts and one NFS share that happen within /var/opt/sun/xvm, so you'll have to manage these when you transfer the storage to the secondary Enterprise Controller. Unlike on the primary, on the secondary Enterprise Controller you install the Sun xVM Ops Center software before you transfer the /var/opt/sun/xvm directory structure to it.

All of this is documented in the High Availability section of the 2.1 wiki. Have a look through this if you're interested in the HA solution.
