Get & Document DRS Rules

[dloop2]

Can you provide an example for capturing, for system documentation purposes, the DRS rules for cluster?

Thanks,

I would start simply with Get-Cluster. What are you looking for in addition to this?

45# "administrator" | Get-VIServer vcenter
46# Get-Cluster

Name                           HAEnabled  HAFailover DRSEnabled DRSMode
                                          Level
----                           ---------  ---------- ---------- -------
HA-Cluster                     False      1          True       Manual

Affinity, anti-affinity rules.

The following script lists for all cluster all rules and for each rule the guests involved.

Get-Cluster | %{Get-View $_.ID} | %{
  $confEx = $_.ConfigurationEx
  if($confEx.Rule -is [array]){
    foreach($rule in $confEx.Rule){
      Write-Host "Rule : " $rule.Name "/Enabled : " $rule.Enabled
      foreach($vmMoref in $rule.Vm){
        $vm = Get-View $vmMoref
        Write-Host "VM : " $vm.Name
      }
	}
  }
}

The script uses the ClusterConfigInfoEx object to get to the rules.

Note that the API v2.5 advises to use this object instead of the ClusterConfigInfo object.

The test if($confEx.Rule -is [array]) avoids running through the loop when there are no rules defined.
