Automating VMware Snapshot Consolidation with PowerCLI

 Here’s a simple PowerCLI script to consolidate VMware snapshots from vCenter. This script will iterate over all VMs in the vCenter, check for any snapshots, and then consolidate them if necessary.

** Please make necessary changes to fit your infra requirement.**

Prerequisites:

• Ensure you have VMware PowerCLI installed and connected to your vCenter server.
• The script user should have permission to manage snapshots and VM tasks.

PowerCLI Script to Consolidate Snapshots:

# Connect to vCenter Server

Connect-VIServer -Server <vCenter_Server> -User <username> -Password <password>

# Get all VMs in the vCenter

$vms = Get-VM

# Loop through each VM

foreach ($vm in $vms) {

    # Check if the VM has snapshots

    $snapshots = Get-Snapshot -VM $vm

 

    # If there are snapshots, attempt consolidation

    if ($snapshots) {

        Write-Host "VM '$($vm.Name)' has snapshots. Consolidating..."

 

        # Consolidate snapshots for the VM

        try {

            $vm | Get-Snapshot | Remove-Snapshot -Confirm:$false

            Write-Host "Snapshot consolidation complete for '$($vm.Name)'."

        }

        catch {

            Write-Host "Error consolidating snapshots for '$($vm.Name)': $_"

        }

    }

    else {

        Write-Host "VM '$($vm.Name)' has no snapshots."

    }

}

 

# Disconnect from vCenter

Disconnect-VIServer -Server <vCenter_Server> -Confirm:$false
