How to verify ESX host have DRS Enabled with Powershell

[Skark166]

Ok, I've been stumbling arround with this for a while. I'm trying to write a script that will verify our systems are good for HA Failover and DRS. One of the main criteria is that the ESX host has DRS enabled. However, the only properties I can find for DRS is related to the cluster. Is there way to check the DRS Settings on an ESX host via script?

Thanks,

Afaik there is no direct method to find out if a host has HA and/or DRS enabled.

These settings are kept with the cluster.

This script runs through all the hosts, that are in a cluster, for all the clusters to find the target host.

If found the script says if HA and/or DRS are enabled.

$esxtgt = <ESX-hostname>

Get-Cluster | Get-View | %{
  foreach($h in $clus.Host){
    if((Get-View $h).Name -eq $esxtgt){
      Write-Host $esxtgt
      Write-Host "`tDRS enabled : " $_.Configuration.DRSConfig.Enabled
      Write-Host "`tHA enabled  : " $_.Configuration.DasConfig.Enabled
    }
  }
}

Hmm...that script isn't working for me, I get a NULL value error...I am a bit of a noob at this stuff tho, perhaps I'm doing something wrong. I entered my ESX Host name for the $esxtgt var and ran.

Two points to check:

1) You did connect (Connect-VIServer) to your VC ?

2) You do have a cluster in your VI ?

Yes, and Yes.

We just have one cluster with 3 esx hosts.

Just noticed, a typo in my script.

Try this:

$esxtgt = <ESX-hostname>
 
Get-Cluster | Get-View | %{
  foreach($h in $_.Host){
    if((Get-View $h).Name -eq $esxtgt){
      Write-Host $esxtgt
      Write-Host "`tDRS enabled : " $_.Configuration.DRSConfig.Enabled
      Write-Host "`tHA enabled  : " $_.Configuration.DasConfig.Enabled
    }
  }
}
