How to Configure Novell Clustering with VMware ESX Server
The following Novell support article details how to configure Novell Clustering on VMWare ESX server and not cause you to pull your hair out.
There are two ways to do Novell Clustering on the ESX server (that I have found).
The first way is to use RAW LUN mapping for each Virtual Machine(VM).
The second way is to use VMWare Virtual Disks.
Using Raw Lun Mapping is a bit limiting in the sense that VMWare only allows you to have one Raw Lun Mapping per ESX server. So in order to cluster you need to have two physical servers. This is a good idea anyway but there is a further issue, if you are using VMWare to run multiple servers only one of those servers can be clustered. So in my instance we have a IBM Blade server with 5 Blades, each blade has 8GB of RAM and 2 Quad Core CPU’s, I can run many NetWare servers on this and I want to cluster a few of them. With Raw Lun mapping I can only have one clustered server per ESX server and the second clustered node will have to be on another ESX server.
Using the VMWare disks allows me to have multiple clustered servers on each blade with their counterparts on other blades or on the same blade. The issue with using VMWare disks is that it is harder to configure the Raw Luns.
I will go over Raw Lun config first because it is real easy and fast.
