I deleted and added vmdk disk using right clicking VM Edit setting .
I had error
invalid snapshot configuration was detected
when taking snapshot and could not take snapshot like below.
How could I add and delete vmdk disk to/from Guest OS properly ?
Looking at Cause of below KB,
it says
This issue occurs if the removed disk is still in the snapshot database. If you examine the vmware.log file for the virtual machine, it contains an entry that indicates that it cannot find the base VMDK for the disk that was removed. This may occur if the files were manually deleted via the service console or the datastore browser instead of through the virtual machine's Edit Settings dialog or if the .vmsd file is corrupted as well.
