An administrator has multiple vCenter Server 6.5 systems but cannot enable Storage I/O Control (SIOC) on a datastore shared by ESXi hosts managed by the vCenter Server systems.
Which action should the administrator take to resolve the issue?
A . Unmount the datastore and then enable SIOC on the vCenter Server system.
B . Configure the datastore to be managed by a single vCenter Server system.
C . Configure Storage DRS and then enable SIOC on the vCenter Server system.
D . Enable Raw Device Mapping (RDM) on the ESXi hosts.
Before enabling SIOC, ensure that datastores are managed by a single vCenter Server.
