![]() 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 Warning Virtual Machine disks consolidation is needed on the Virtual tab of the virtual machine in the VMWare vSphere console means that deleting the. You should immediately get the ‘needs consolidation’ message in the vSphere client. This will remove the snapshot, without committing the delta files. If you want to test the process, create a snapshot on your virtual machine, then run the following in PowerCLI: Virtual machine disk consolidation is needed can pop up when merging multiple virtual disk files on the VMware vSphere Client. When you see this, you can run a Consolidation on the virtual machine to commit the delta files to the base disk: In vCenter the machine has this notice: Virtual machine disks consolidation is needed The only snapshot is the Veeam snapshot. A Not Required status indicates that the files are consolidated. A Yes status indicates that the snapshot files for the virtual machine must be consolidated. Figure A below shows this option added to the list of virtual. ![]() Now, when a VM has had issues consolidating its snapshots you will see a message on the Summary tab for the virtual machine: Click the VMs tab and click Virtual Machines. Within the vSphere Client, you can add a column to the view to display if the virtual machine needs to have consolidation performed. This could lead to problems where a VM that didn’t look as though it had any active snapshots, was still actually writing to the delta files. This was done to address an issue where, when doing a snapshot removal, the delta files would not be merged with the base disk but would be removed from visibility in the vSphere client. ![]() Further to that, I thought I’d cover a bit on Snapshot Consolidation With vSphere 5, a new feature was added to allow you to consolidate snapshots. Basically theres a problem with the machine snapshots, If you right click the VM > Snapshots > Consolidate. I’ve written a post recently around creating snapshots using the ESXi CLI. ![]()
