    When EMUL7K_MODE is set to 1, DLT 7000 emulation is enabled on the drive. When EMUL7K_MODE set to 0, it restores the drive to standard DLT 8000 operation. After the DLT 7000 Emulation Mode feature has been enabled, it is critical that you reinitialize the SCSI bus interface using one of the following methods: Issue a bus reset (this resets all devices on the bus);...

    SCSI opcodes that exist for a DLT 7000 drive will have an identical response on a DLT 8000 drive with emulation enabled. Note that SCSI opcodes that are not compatible with a “real” DLT 7000 drive are supported by a DLT 8000 drive in DLT 7000 emulation mode.
