If any are found, you can start a consolidation task by running: (Get-VM -Name "VirtualMachineNameGoesHere").ExtensionData. You can use PowerCLI to list all VMs that need consolidation by running: Get-VM | Where-Object Snapshot.needConsolidate = "TRUE" Using PowerCLI to Find Virtual Machines that need Snapshot Consolidation If you look at the contents of the *.vmsd file in the virtual machine’s working directory, you should see the following if consolidation is required: /vmfs/volumes/4f27b82e-3fc1540e-bf6b-000c295da2d9/XP3 # cat XP3.vmsd You should immediately get the ‘needs consolidation’ message in the vSphere client.

Enter the Group World ID (the value in the GID column) and press Enter. Microsoft Exchange Server on VMware vSphere. I created a snapshot, then an option for Consolidate was available to me. Youll need enough memory for the host and all virtual machines that you. In vCenter, I have a information alert (blue, not yellow or red) for 'Virtual machine disks consolidation is needed.' When I first viewed the VM, there were no snapshots. I’ve written a post recently around creating snapshots using the ESXi CLI. Find the virtual machine running the consolidation.
