This OID is a 64-bit access-control bitmask governing which UCS Manager roles or locales are permitted to modify the properties of the iSCSI initiator node object representing the initiator identity used by an iSCSI vNIC (IScsiNode). An admin auditing role-based access control cares about this value because it determines whether a given operator role can actually change this IScsiNode instance's configuration or only view it. For example, a security-conscious admin restricting storage-network changes to a 'storage-admin' locale would expect this ACL bitmask to reflect that restriction on every IScsiNode object in that domain.
