VMware PowerCLI 101 - part11 - Get vCLS cluster state

vSphere Cluster Services (vCLS) is a feature introduced in vSphere 7.0 Update 1 to ensure the availability of cluster services like DRS and HA, even if the vCenter Server becomes unavailable. It provides a distributed control plane for clustering services, improving scalability and resilience.

> Get-Cluster | select Name, @{N="VcsHealthStatus";E={$PSItem.ExtensionData.SummaryEx.VcsHealthStatus}}  
  
Name                    VcsHealthStatus  
----                    ---------------  
Cluster-01              healthy  
Cluster-02              healthy

Hope it was useful. Cheers!

VMware PowerCLI 101 - Part2 - Working with vCenter server

In my previous blog, we discussed how to install PowerCLI module and connect to a stand-alone ESXi host. Now let's start with connecting to the vCenter server.

Connect-VIServer <IP of vCenter server>

Get the list of data centers present under this vCenter server: Get-Datacenter


Get the list of clusters under a datacenter: Get-Datacenter DC01 | Get-Cluster

To verify the status of HA, DRS, and vSAN of a cluster:
(Get-Cluster Cluster01) | select Name,DrsEnabled,DrsAutomationLevel,HAEnabled,HAFailoverLevel,VsanEnabled


Get the list of ESXi hosts part of a specific cluster: 
Get-Datacenter DC01 | Get-Cluster Cluster01 | Get-VMHost


To get the list of VMs hosted on a specific ESXi host:
Get-Datacenter DC01 | Get-Cluster Cluster01 | Get-VMHost 192.168.105.11 | Get-VM


To get a list of powered on and powered off VMs:
(Get-Cluster Cluster01 | Get-VM).where{$PSItem.PowerState -eq "PoweredOn"}
(Get-Cluster Cluster01 | Get-VM).where{$PSItem.PowerState -eq "PoweredOff"}


An efficient way of doing it in a single go is given below:
$vmson, $vmsoff = (Get-Cluster Cluster01 | Get-VM).where({$PSItem.PowerState -eq "PoweredOn"}, 'split')

$vmson will have the list of VMs that are PoweredOn and $vmsoff will have the list of VMs that are PoweredOff.


Cluster level inventory:
Get-Cluster | Get-Inventory

Datastore details of a cluster:
Get-Cluster | Get-Datastore | select Name, FreeSpaceGB, CapacityGB, FileSystemVersion, State


Hope this was useful. Cheers! In the next post, we will talk about performing basic VM operations using PowerCLI.
