6.2 Field Definitions

Byte 01, Bit 1 - Immed

The Immed bit is used to determine when command status is

returned to the initiator, as follows:

0 – Status is reported to the initiator when the load/unload operation

is complete.

1 – Status is reported to the initiator when the command is initiated

by the CTS.

If the buffer contains data from a previous WRITE command, the CTS

disconnects from the SCSI bus (if disconnect was enabled by the

Identify message) and writes the data in the buffer to the tape.

If the Immed bit is set to 1, the CTS reconnects to the initiator

when the write operation has been completed successfully. It then

returns Good status and performs the load or unload operation.

Note: Completing the write operation includes emptying the

buffer and writing the EOD mark (8200c, 8500, and 8500c

format tapes only).

If the Immed bit is set to 0, the CTS reconnects and returns status

when the load or unload operation is complete.

If an error occurs during the writing of the data from the buffer to the

tape, the CTS reconnects to the initiator and returns Check Condition

status. The load or unload operation is not performed. The initiator

should issue a REQUEST SENSE (03h) command to determine the

cause of the error.

Byte 04, Bit 2 - EOT

This bit is ignored by the CTS.

Byte 04, Bit 1 - Re-Ten

This bit is ignored by the CTS.
