I've been looking at both WMI and the native clustering APIs and can find
nothing that allows me to programmatically update the cluster configuration.
To make things even more difficult, it doesn't look like the PowerShell
commandlet was available until R2 (but maybe I'm wrong). The same PS command
I use to update the Cluster configuration in Server 2008 R2, I can not get to
work in Server 2008 RTM.
So to be clear, in Server 2008 RTM, I have been unable to find any API call
using WMI, the native cluster APIs, or even PowerShell that will allow me to
refresh the virtual machine configuration.
I have been looking at updating the cluster database via direct Registry
edits and I think I can make that work, but to go to that extreme seems to be
a bit of a hack and prone to error ... it's something I would prefer to not
to have to do.
Any suggestions?
