Get list of hosts available to run a VM?

[EdZ]

I've searched the forums but haven't found the answer for this, but please let me know if I missed it. Given a VM name, I would like to output a list of hosts that the VM can run on. The only way that I have been able to do this is a two step process and I'm trying to get it into a one liner:

Suppose the VM name is SQLVS01

$a = foreach ($vmname in get-vmhost -vm SQLVS01){get-cluster -vmhost $vmname}

Check the value of $a for example purposes:

$a

Name HAEnabled HAFailover DrsEnabled DrsAutomationLe

Level vel

-

---

-

---

-

---

-

---

-

---

SQLCluster1 True 1 True FullyAutomated

Use the retrieved cluster name as a parameter:

C:\> get-vmhost -location $a.name

Output shows the VMHosts in that cluster

Name

-

---

VMHost1

VMHost2

..etc..

Any ideas? This must be simpler than I am making it.

Thanks,

Ed

How about this?

get-vm SQLVS01 | get-cluster | get-vmhost | select name

Works like a charm! I tried something similar but it gave me an error that pipeline input was not supported by the object, so the syntax that I used must have been off. Thanks!

The problem with that solution is that it won't take into account when one of those hosts is for example in maintenance.

This is a bit more complex but should take hosts that are powered off or in maintenance into acocunt.

$vmName = <vm-name>
$vmCompatChecker = Get-View (Get-View ServiceInstance).Content.vmCompatibilityChecker
$hosts = $vmCompatChecker.CheckCompatibility((Get-Vm -Name $vmName | Get-View).MoRef,$null,$null,"hostTests")
$hosts | %{(get-view -Id $_.Host).Name}

Could you not also do it this way?

get-vm SQLVS01 | get-cluster | get-vmhost | where {$_.State -eq "Connected"} | select Name

Probably you're right.

Problem is that I don't know what exactly is in those "hostTests".
