Before you continue please consider clicking on one of the horrible ads. I know they are a pain but they help me pay for the hosting of this site. It owes me a lot of money. Sob story over.
I recently found myself in the situation where I was asked to produce a report on how many Hyper-V Vm's existed but have not been added as roles to failover cluster manager, which seems like a pretty simple task but presented its own set of challenges.
So lets do it.
- Get a list of VM's from each Hyper-V host, then
- Get a list of roles from Failover cluster manager then
- compare these 2 lists
- Wait 100 years for all this to finish.
Anyone that has used failover cluster manager is probably aware that when you add a new VM you are presented with a list of VM's that "qualify" to be clustered services, so you would think there is a quicker way... and there is!
Lets take a closer look at a VM object.
In more detail:
Can you see it? Look closer.
Did you know that was there? I didn't. This makes it much easier. We can now do this with a simple one liner.
get-vm | where{$_.IsClustered -eq $false}This will get you VM's that arent clustered on a single host. To expand this to a whole cluster
$ClusterNodes = Get-ClusterNode
foreach($ClusterNode in $ClusterNodes)
{
get-vm | where{$_.IsClustered -eq $false}
}
