LOG SENSE COMMAND (4Dh)

The LOG SENSE command provides a method for the application client to retrieve statistical or other operational information maintained by the SCSI target device about the SCSI target device or its logical units. The command is complementary to the LOG SELECT command. The only LOG SENSE page code supported is 0x00. The PPC and SP bits (Bits 1 and 0 of CDB Byte 1) must be zero and the PC bits must select the cumulative values (CDB Byte 1 must be set to 0x40). Bytes 1, and 5 through 8, are not supported. The Drive will return a CHECK condition if non-zero. Byte 2 must be 0x40, as only cumulative values are supported.
