How to remove locked snapshots ?

Hello,

One of VM has 20 snapshots and cannot be removed by snapshots manager.

And checked can use CLI to remove them: http://kb.vmware.com/kb/1002310

Question here

I checked the VM using PTDC01-000020.vmdk, is it mean I just remove other snapshots PTDC01-000001.vmdk - PTDC01-000019.vmdk

by command line ? and CLI can remove locked snapshots ?

Thanks !
