    DLT4000 SCSI Interface 8.2.6 Data Cache and Tape Write Interaction The DLT4000 drive contains a data cache that buffers blocks (records) until they are written. This section defines specific times that blocks are written to the tape. A Mode Select parameter allows the data cache to be disabled (unbuffered mode). In this mode, every WRITE command will cause the data to be written to the media before the STATUS byte and the COMMAND COMPLETE message is returned to the host.

    STATUS phase is requested by the initiator. The only exception is during error cases when the device Status bytes the tape drive returns are as follows: REQUEST SENSE command should be sent following this status to determine unable to accept a command from an otherwise acceptable initiator.

    DLT4000 SCSI Interface When received from an initiator, the tape drive may respond in one of two ways. First, it may take the message as a request by the initiator to disconnect and comply by entering message in phase and sending the DISCONNECT message back to the initiator (possibly preceded by the SAVE DATA POINTERS message).
  • Page 171 IDENTIFY (80h-FFh) These messages are sent either by the initiator or by the target to establish (or reestablish) the physical connection path between an initiator and target for a particular logical unit. The message byte consists of the following bits: Bit 7: Always set to one.
