Part of a powershell script I'm writing requires the ESX host moref value... like this:
host-746
I've found away of finding the moref value with:
$vmhost = "esx4.vi4book.com"
$esxhost = Get-VMHost $vmhost
$hostview = $esxhost | Get-View
$hostview.moref
But when I insert $hostview.moref into the method i'm using it returns an error... I think it because $hostview.moref doesn't return just the moref value but other parameters as well, and need away of just present the raw value - host-746...
Any ideas?

(That would be nice to see - Carter's demo).
In one respect it's quite gratifying that I got the main part of the script right. It suggest that I am very slowly getting used to navigating around the SDK - which isn't the most intuitive thing to do on the planet...
On separate note. I notice Stu was saying that he intermitent issue with making the script work. I found if I merely attached to the ESX host and ran the PS, then it hated it...
However, if I ran the script AFTER I'd used the add-host cmdlet, it worked....
So one thing seems clear. That to configure DPM the host must be in vCenter first. Added my ESX host to a DRS cluster (not DPM enabled by the way) and found that the script work even if DPM hadn't been enabled on the cluster...
The way I'm doing my configuration is - I attach directly to the ESX host and pop it into maintenance mode. I do everything I need to do (vswitches, iscsi, nas, ntp - the usual suspects), then I add the host to vCenter. Leaving it in maintenance mode - with the option to exit if everything is good. This way an ESX host doesn't become a target for VMs until someone manually verifies the PS has worked correctly... What I'm doing is pretty crude, and I'm trying to write the powershell in a "dummies" way so anyone reading it can see right away what it's doing... in effort to make the move away from esxcfg-commands to PS as painless as possible...

ROFL!!!!
Thanks for that, you really are too kind
I initially got caught out with the direct host connection too, this is one of those wierd settings that is relevant only to a cluster (and therefore is a construct of vCenter rather than a host), but yet is defined in a host property. This is a little contradictory, for example with DPM in mind you would think that configuring the HA related isolation response settings of a VM would be a property of the VM, but it's not - there's an array that is a property of the cluster, and depending on what setting you configure a VM will or won't appear in that array. So I was expecting the same for the DPM settings, and was surprised when it actually was a host property.
Just one of those quirks I guess, part of the joy of stumbling your way around the SDK - which you are obviously doing as well as any of us these days
Stu
when using the script I receive an error...
C:\Program Files\VMware\Infrastructure\vSphere PowerCLI> $esx
MoRef.UpdateIpmi($IpmiInfo)
Exception calling "UpdateIpmi" with "1" argument(s): "The operation is not supp
orted on the object."
At line:1 char:21
+ $esxMoRef.UpdateIpmi <<<< ($IpmiInfo)
+ CategoryInfo : NotSpecified: ( [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
But I'm unable to find any useful info on the error, has anyone run into this or can guid me as to what I am doing wrong?
Thank you for your time and assistance,
Scott
This is what I wrote and works for me:
$vmhost = "esx4.vi4book.com"
$login = "vmware_dpm_user"
$password = "password"
$hostview = get-vmhost $vmhost | % {Get-View $_.Id}
$IpmiInfo = New-Object Vmware.Vim.HostIpmiInfo
$IpmiInfo.BmcIpAddress = “192.168.3.204″
$IpmiInfo.BmcMacAddress = “00:16:35:37:F8:02″
$IpmiInfo.Login = $login
$IpmiInfo.Password = $password
$hostview.UpdateIpmi($IpmiInfo)
