Save Data Pointer 02H
This message is sent from the target to direct the initiator to save a copy
of the present active data pointer for the currently attached logical unit.
The drive may issue this message when it disconnects from the SCSI Bus
during data transfer.
Restore Pointers 03H
This message is sent from the target to direct the initiator to restore the
most recently saved pointers to active state. The target may send this
message when a bus error has occurred during the Data In or Status
Phase.
Disconnect 04H
This message is sent from the target to inform an initiator that the
present physical path is going to be broken, but that a later reconnect is
required to complete current operation.
Initiator-Detected Error 05H
When the target receives this message during Data In or Status Phase, it
may retry the transfer after sending a Restore Pointers message.
Abort 06H
This message is sent from the initiator to the target to clear the present
operation. All pending data and status that was made by the current
command is cleared and the target goes to the Bus Free Phase. Pending
data and status for other initiators are not cleared. No status or ending
message is sent for the operation.
