Virtual Machine disks consolidation failed

Hi People,

What should I do to consolidate the VMware VM that is currently displaying the error message as follows:

Configuration Issues
Virtual Machine disks consolidation is needed

Usually when the EMC Avamar backup failed to close the snapshot what I usually do is right click on the VM and then Delete all the snapshot from Snapshot manager.

This time the Delete snapshot task was successfully completed BUT the consolidation was reported as failed ?

resulting the VM hard disk 1 to point into DevOPS01-VM-000002.vmdk

Any suggestion would be greatly appreciated.

What we do is as follows:-

(Check that the Backup Appliance or Job Does NOT have a lock on the Virtual Machine Disk - if it does remove the disk from the appliance)

often no snapshot will appear in snapshot check if a snapshot exists, see my EE Article

HOW TO: VMware Snapshots :- Be Patient

and then do the following:-

1. In Snapshot Manager - Take a new snapshot

2. Wait at least 60 seconds


Be Patient.

yes, there are two VMDK with -00001 and -00002 files with the same name of the VM.

so what about right click and selecting "Consolidate" option ?
I've never tried this before, so I'm wondering what does it do to the VM ?

can I still do it while the VM is online ?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Yes, VM offline or online,  just check you have enough storage space for the snapshot merge.

Consolidate is supposed to do the same, but in my experience it's hit and miss.
