MPxIO doesn't support socal because firstly socal was written before the Leadville stack and secondly - socal as a physical device was EOLd looooong ago and the engineering effort required to bring it into compliance with Leadville was not worth it. HBA drivers have to be written to comply with the interface requirements of MPxIO, and if they do not comply then you cannot use them as MPxIO- capable devices. You can investigate this further by looking through the source for the NWS Consolidation http://src.opensolaris.org/source/xref/nwsc/src/sun_nws/ and at sunmdi.c, sunndi.c and scsi_vhci.c in the ON consolidation: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/os/sunmdi.c http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/os/sunndi.c http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/io/scsi/adapters/scsi_vhci/ James C.
