Error Msg 6 :
Configuration Issues : Virtual machine disks consilidation needed. Cause : When initiating Delete or DeleteAll operations on snapshots, the snapshot details are deleted from Snapshot Manager, then the snapshot files are consolidated and merged to another snapshot file or to the virtual machine parent disk. If the consolidation fails, there were no snapshots shown in the Snapshot Manager, but the snapshot files were still being used on the datastore. This can cause the datastore to run out of space.
Solution : 1. Right Click Virtual Machine and click Snapshot > consolidate
Note : this feature is available only form 5.1 Version , this enabled administrators to consolidate the snapshot from vsphere client rather than logging in to ESXI host.
