The time has finally come to retire the VESI (Virtualization Ecoshell) and install the latest PowerGUI (v2.3.0). I’ve known for a while now that the VESI’s functionality was being merged back into PowerGUI. I’ve been putting it off for a bit while waiting for the VMware PowerPack to be updated for PowerCLI 4.1. Well, today is the day. (Or, rather, last week was the day.)

Managing VMware HA’s VM Monitoring: PowerCLI
In a previous post, I discussed my need to manage HA isolation response and restart priority settings on a per-VM level (separate from the cluster settings). This post is a continuation of that topic, but covers how to manage the VM Monitoring aspect of VMware HA with PowerCLI.
At the time of writing, there are no publicly available PowerCLI cmdlets that offers the ability to manage VM Monitoring at the cluster and VM levels, so in order to accomplish this task, we need to dive a bit deeper into the world of the vSphere API.

VMware HA Restart Policies: PowerCLI
Recently I received a request to disable any automated HA actions on specific VMs across our infrastructure. To some folks that might sound a bit crazy, but there was good reason: an outside vendor supports an application and wanted to be involved any time the VM was powered up/down/etc. They have contractual obligations with business units within our company, and wanted to be sure that their application stack was started in an application-graceful way.

Finding mismatched NFS datastore UUIDs: PowerCLI
I’ve run into an issue lately in my VMware environment that really frustrated me because I didn’t understand why it was happening, and because there wasn’t an obvious way of determining that it wouldn’t happen again. The problem I’d been having was mismatched UUIDs on NFS datastores on clustered hosts. It’s a configuration issue that isn’t apparent until you need to vMotion a VM or are relying on HA/DRS.

Controlling VMware Update Manager patch staging: PowerCLI
As you may be aware, VMware Update Manager has functionality built-in that allows the VMware administrator to stage patches to hosts, for remediation at a later time. There are a number of downsides to the way this functionality is implemented in the VMware VUM GUI.
