s nonvolatile storage. SCSI_IO_REQUEST 0x00 Initiate a SCSI I/O on a target device. SCSI_TASK_MGMT 0x01 Send a task management command to a target device. SCSI_ENCLOSURE_PROCESSOR 0x18 Communicate with an SES device. RAID_ACTION 0x15 Perform an action on or receive status information from an Integrated RAID volume. RAID_SCSI_IO_PASSTHROUGH 0x16 Send an I/O to the hidden physical disk of Integrated RAID volume. TARGET_CMD_BUF_BASE_POST 0x24 Post base address of command buffer pool to the IOC. TARGET_CMD_BUF_LIST_POST 0x25 Repost an IoIndex to the IOC after it has been used. TARGET_ASSIST 0x0B Continue an I/O as a SCSI target. TARGET_STATUS_SEND 0x0C Send status for an I/O as a SCSI target. TARGET_MODE_ABORT 0x0D Abort a target mode request message. SMP_PASSTHROUGH 0x1A Send SMP functions to a SAS expander. SATA_PASSTHROUGH 0x1C Send SATA commands to an attached SATA device. SAS_IO_UNIT_CONTROL 0x1B Control the SAS IO Unit. CONFIG 0x04 Access or modify operational parameters of the IOC. TOOLBOX 0x17 Send a non-I/O tool request to the IOC. DIAG_BUFFER_POST 0x1D Post a diagnostic buffer to the IO Unit. DIAG_RELEASE 0x1E Request the IO Unit to release a diagnostic buffer. RAID_ACCELERATOR 0x2C Initiate a RAID Accelerator operation. HOST_BASED_DISCOVERY_ ACTION 0x2F Perform an action on a device instance during Host Based Discovery. PWR_MGMT_CONTROL 0x30 Control power management features on the IOC. MIN_PRODUCT_SPECIFIC 0xF0 Beginning of the product-specific range of function codes. Values 0xF0 to 0xFF are reserved for product-specific use. See product-specific documentation for details. MAX_PRODUCT_SPECIFIC 0xFF End of the product-specific range of function codes. Values 0xF0 to 0xFF are reserved for product-specific use. See product-specific documentation for details. 2.2.2 消息配置功能 通过消息机制,可以对IO单元进行配置,也可以进行不同的设置.主机(在OS中)可以使用配置请 求消息(Configuration Request Message)来访问IOC的可操作参数.这些可操作参数分成多个逻辑组,称 之为Pages.这些page根据不能操作范围,进而划分不同page类型,如IO Unit Pages、IOC Pages等,且通 过不同的page号码访问. 所有的参数都必须基于page方式来访问.如果主机只想修改page中的某一个域,必须先page读出, 再修改,最后回写.每个page都有属性,如只读等. 下表为配置请求消息(Configuration Request Message)格式.
