Using Storage Foundation in the logical partition (LPAR) with virtual SCSI devices
Storage Foundation provides support for virtual SCSI (vSCSI) devices on the VIO client. You can create and manage Veritas Volume Manager (VxVM) volumes on vSCSI devices, as on any other devices. Storage Foundation provides Dynamic Multi-Pathing (DMP) for vSCSI devices, by default. Storage Foundation can also co-exist with MPIO for multi-pathing. If you choose to use MPIO to multipath the vSCSI devices, DMP works in pass-through mode.
Use the vxddladm utility and the vxdmpadm utility to administer DMP for vSCSI devices. The vxddladm utility controls enabling and disabling DMP on vSCSI devices, adding and removing supported arrays, and listing supported arrays. The vxdmpadm utility controls the I/O policy and the path policy for vSCSI devices.
