Environment
VMware Site Recovery Manager 8.x
Cause
This issue is caused when Storage I/O control is enabled on the datastore, which creates a mix of unprotected and protected virtual machines on same datastore.
Resolution
To resolve this issue:
Move the unprotected virtual machines to another datastore.
