4.2 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 ERASE command is

completed.

1 – Status is reported to the initiator when the ERASE 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 erase operation.

Note: Completing the write operation includes emptying the

buffer to tape 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 erase and rewind operations are complete.

Byte 01, Bit 0 - Long

The Long bit determines the amount of tape to be erased, as follows:

0 – The command is accepted, but no erase operation is performed.

1 – All tape will be erased from the current position to PEOT.

Byte 05, Bits 7 and 6 - Vendor Unique

There are no vendor unique definitions for this command.
