* Definitions of SCSI messages.
|
|
*
|
|
* SCSI_COMMAND_COMPLETE - After a command has completed, successfully
|
|
* or not, this is returned to the host from the target.
|
|
*
|
|
* SCSI_EXTENDED_MSG - Indicates that a multi-byte message is being sent.
|
|
*
|
|
* The following messages are used with connect/disconnect:
|
|
* SCSI_SAVE_DATA_POINTER - Sent from target to host to request saving
|
|
* of current DMA address and count. Indicates a pending dis-connect.
|
|
* SCSI_RESTORE_POINTER - Sent from the target to the host to request
|
|
* restoring pointers saved before a disconnect
|
|
* SCSI_DISCONNECT - Sent from the target to the host to disconnect.
|
|
* SCSI_ABORT - Sent from the host to the target to abort current request.
|
|
* SCSI_MESSAGE_REJECT - Indicates receipt, by either host or target, of
|
|
* an unimplemented message.
|
|
* SCSI_NO_OP - Sent from host to target if it has no real message to send.
|
|
* SCSI_MESSAGE_PARITY_ERROR - Sent from host to target on message parity error
|
|
* SCSI_BUS_RESET - Sent from host to target to reset all current I/O
|
|
*
|
|
* SCSI_IDENTIFY - The low order two bits of this message type indicate
|
|
* the Logical Unit of the Target which is requesting a reconnect.
|
|
* SCSI_DIS_REC_IDENTIFY - Sent from the host to a target to indicate
|
|
* is supports connect/dis-connect
