Using Storage Foundation with virtual SCSI devices
Storage Foundation identifies the vSCSI LUNs through the array properties of the LUNs. Otherwise, the devices in the VIO client or logical partition (LPAR) appear as regular SCSI disks.
Storage Foundation supports vSCSI disks with version 5.1MP1 and later.
Portable Data Containers (disk type CDS) are supported. With extensions included in Storage Foundation 5.1, CDS type devices are now supported.
Storage Foundation can be deployed in the following ways:
Use DMP in the VIO server to provide multi-pathing to the array. DMP presents a dmpnode as a vSCSI device to the LPAR.
Use Storage Foundation in the LPAR to provide volume management on the vSCSI devices, and multi-pathing through the VIO servers with DMP.
Use Storage Foundation in the LPAR to provide volume management on the vSCSI devices, and use MPIO to provide multi-pathing.
