We do not support MODE SENSE mode page 0x03 (which is what the reported problem-CDB represents) for SATA disks attached through a SATA hba.
In fact our code has a specific comment about this "Page 3 and 4 are obsolete and we are not supporting them." (http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/io/sata/impl/sata.c#5116)
Proposed fix is to modify sd driver's sd_get_physical_geometry() function so that it will return before sending the MODE SENSE (6) mode pages 0x03 and 0x04 CDBs to the disk.
