It is pretty straightforward, but is handy for identifying those VMs that are, say, at a different EVC mode than is configured on the cluster. So, the code:
function Get-VMEVCMode {
<# .Description
Code to get VMs' EVC mode and that of the cluster in which the VMs reside. May 2014, vNugglets.com
.Example
Get-VMEVCMode -Cluster myCluster | ?{$_.VMEVCMode -ne $_.ClusterEVCMode}
Get all VMs in given clusters and return, for each, an object with the VM's- and its cluster's EVC mode, if any
.Outputs
PSCustomObject
#>
param(
## Cluster name pattern (regex) to use for getting the clusters whose VMs to get
[string]$Cluster_str = ".+"
)
process {
## get the matching cluster View objects
Get-View -ViewType ClusterComputeResource -Property Name,Summary -Filter @{"Name" = $Cluster_str} | Foreach-Object {
$viewThisCluster = $_
## get the VMs Views in this cluster
Get-View -ViewType VirtualMachine -Property Name,Runtime.PowerState,Summary.Runtime.MinRequiredEVCModeKey -SearchRoot $viewThisCluster.MoRef | Foreach-Object {
## create new PSObject with some nice info
New-Object -Type PSObject -Property ([ordered]@{
Name = $_.Name
PowerState = $_.Runtime.PowerState
VMEVCMode = $_.Summary.Runtime.MinRequiredEVCModeKey
ClusterEVCMode = $viewThisCluster.Summary.CurrentEVCModeKey
ClusterName = $viewThisCluster.Name
})
} ## end foreach-object
} ## end foreach-object
} ## end process
} ## end function
And, some examples: Get EVC mode info for all of the VMs in this cluster:
PS vN:\> Get-VMEVCMode -Cluster myCluster Name PowerState VMEVCMode ClusterEVCMode ClusterName ---- ---------- --------- -------------- ----------- somesvr01.dom.com poweredOn intel-westmere intel-westmere OurCluster somesvrlm1.dom.com poweredOn intel-penryn intel-westmere OurCluster somesvrbs03.dom.com poweredOff intel-westmere OurCluster somesvrxp.dom.com poweredOn intel-penryn intel-westmere OurCluster ...
For all of the VMs in this cluster where their EVC mode does not match the config'd cluster EVC mode, return their info:
PS vN:\> Get-VMEVCMode -Cluster myCluster | ?{($_.VMEVCMode -ne $_.ClusterEVCMode) -and ($_.PowerState -eq "poweredOn")}
Name PowerState VMEVCMode ClusterEVCMode ClusterName
---- ---------- --------- -------------- -----------
somesvrlm1.dom.com poweredOn intel-penryn intel-westmere OurCluster
somesvrp83.dom.com poweredOn intel-penryn intel-westmere OurCluster
somesvra.dom.com poweredOn intel-merom intel-westmere OurCluster
...
Note: The function does expect that you are using at least PowerShell v3, which surely everyone is well beyond by now, anyway. But, if not, the "[ordered]" cast should be the only thing one would need to take out in order to use in older PowerShell versions.
Straightforward, and uses everyone's favorite PowerCLI cmdlet, Get-View, so you know that it is FaF! Enjoy.
