ddb.sidecarsentry and correct the vmfd filename so that it points to the existing file within the same folder.
VM Name: Sample
vmdf File on disk: Sample-c9c24ae00ec07941.vmfd
Sample.vmdk contains the entry:
ddb.sidecars = "veecdp_1,Sample_675617-62e8e8ccb585c028.vmfd"
This corrected entry is:
ddb.sidecars = "veecdp_1,Sample-c9c24ae00ec07941.vmfd"
