For environments where DMP DSMs are used, 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 settings, the array must be enabled for SCSI-3 Persistent Group Reservations (SCSI-3 PGR).

For more information on DMP DSMs load balance settings and enabling or disabling SCSI-3 PGR, refer to the Symantec Storage Foundation Administrator's Guide.
