When attempting to power on a Virtual Machine you observe the following error: Cannot open the disk '/vmfs/volumes/volume/vm/vm-000002.vmdk' or one of the snapshot disks it depends on. Which three act

Verifying that all virtual machine disk files including snapshot delta disks are present on the datastore directly addresses the 'cannot open disk' error by confirming whether files are missing or mislocated.

Reviewing host and VM log files (vmware.log, hostd.log) provides specific error context such as permission issues, datastore connectivity failures, or lock conflicts that caused the snapshot chain to break.

Snapshot vmdk descriptor files can become corrupted or mismatched; verifying and recreating them restores the metadata that vSphere needs to open the disk and traverse the snapshot chain correctly.

Deleting the disk file that is preventing power-on would result in permanent data loss for that snapshot and is never an appropriate first response to a disk open failure.

Migrating or registering the VM to a different host does not resolve the underlying disk file issue because the vmdk files on shared storage remain inaccessible or corrupt regardless of which host mounts them.
