How to null terminate object properties in Powershell

Summary:
I was working on a script, which I'll post on later, to insert IPMI/iLO/iDRAC configs into my ESXi hosts.  I would get an error the following error consistently no matter what I put into my IPMI object:

Exception calling "UpdateIpmi" with "1" argument(s): "A specified parameter was not correct. 
"
At line:50 char:2
+     $_this.UpdateIpmi($ipmiInfo)
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : VimException

 The short answer, I had to 'null terminate' the properties in my IPMI object.  I don't know 'why' I have to do this, but the vSphere API docs state that this is a requirement.  Quite frankly, I had no idea what this meant.

Solution Example:
To null terminate an object's property, you can simply do like so:
$MyObject = "" | Select Usefulproperty
$MyObject.Usefulproperty =  ("Something" + $null)

Additional Notes:
I'll follow-up w/ a post of the script I put together to do this so that it makes more sense.

NSX-T: Release associated invalid node ID from certificate

Image
Summary: Basically had an expiring certificate registered in NSX-T that was associated to a node_id that is no longer valid.  Long story short, there wasn't anything obvious in API to delete or disassociate a certificate from a node_id for 3.2.2.  Not sure how things got in this state, but annotating for future reference.  This may change in future revisions, so always check API for latest. Details: Effectively had a stale node associated w/ a certificate that was expiring.  Could not delete certificate until that node was disassociated from the certificate. To get certificate details and associated node_id's, you can use the following curl call (UI works too): curl -k -X GET -H "Content-Type: application/json" -u admin https://<manager ip>/api/v1/trust-management/certificates/<cert UUID> Above will return something like this: Below must be run from one of the manager nodes via elevation to root: ONLY RUN THIS IF YOU ARE ABSOLUTELY SURE OF WHAT YOU ARE DO...

NSX-T: vCenter and NSX-T Inventory out of Sync (Hosts in vSphere not showing up in NSX-T)

Image
Summary: NSX-T loses synch w/ vCenter inventory, but statuses don't appear to show an issue.  Basically, you add a host to a vCenter cluster, NSX-T bits should start to automatically installing on new host.  Assuming you've created a Transport Node Profile and associated w/ the cluster.  The problem is that NSX-T doesn't see the new host and its link to the compute manager (vCenter) looks fine. Looks fine, Y U NO WORK!? So what's going on here?  This appears to affect NSX-T 2.5 and 2.5.1.  Cause is unknown. Workaround: Restart the cm-inventory service on each NSX-T mgmt/controller node using API or CLI. Details: If you were to query the status of the cm-inventory via API or CLI, you could query all 3 manager/controller nodes and get a status of running.  Even if the primary node associated w/ the VIP, if configured, is not necessarily in charge of inventory.  So you could restart the cm-inventory service till you are blue in the face ...

MacOS: AnyConnect VPN client was unable to successfully verify the IP forwarding table modifications.

The VPN client was unable to successfully verify the IP forwarding table modification.  A VPN connection will not be established. Summary: I started running into issue utilizing Cisco AnyConnect on my Mac basically complaining about not able to overwrite IP forwarding tables.  This was on 4.6.x.  Since my VPN endpoints were not providing me w/ an updated client and w/ no access to Cisco Anyconnect downloads, my only option was to try openconnect.  It was totally worth it, here is why and how to set it up. PreReqs: Homebrew Installing OpenConnect: Launch MacOS Terminal brew install openconnect Getting VPN IP's/DNS Endpoints from AnyConnect: The information is typically located in your profile xml files located here: /opt/cisco/anyconnect/profile/somethingsomething.xml In the xml file, you are looking for "<HostAddress>typicallyaDNSName.com</HostAddress>" entry.  These are your VPN endpoints that you would need to pass to openconnec...
