For DMP DSMs in a cluster environment, either Active/Active or Active/Passive load balance settings can be used. DMP DSMs automatically set the load balancing to active/passive for disks under SCSI-2 reservation. For Active/Active load balancing in a cluster environment, the array must be enabled for SCSI-3 Persistent Group Reservations (SCSI-3 PGR).

Storage arrays may require additional configuration steps or updates to work with Dynamic Multi-Pathing and MPIO. Contact the manufacturer of the storage array for details.
