SCSI Commands

5.9MODE SELECT (6) / (10) COMMAND (15h / 55h)

The MODE SELECT command (available in either 6- or 10-byte format) enables the host to configure the tape drive. Implementing MODE SELECT and MODE SENSE requires “handshaking” between the host and the drive. Before configuring the drive, the host should issue a MODE SENSE command to the drive to obtain a report of the current configuration and determine what parameters are configurable. The host interprets this information and then may issue MODE SELECT to set the drive to the host’s preferred configuration. The Mode Parameter List described in Section 5.8 is passed from the initiator to the drive during the command’s DATA OUT phase.

Information for the drive is carried on a number of pages, each of which serves to set the tape drive’s operating parameters. The MODE SELECT pages supported, and the sections of this manual that details each page, are:

Except for mode page 3Eh, the tape drive always powers up with its default configurations set. This is also true if the drive receives a BUS DEVICE RESET message or a hard reset via the RST line on the SCSI bus.

The Command Descriptor Block is illustrated in Figure 5-32.

For a list of changeable parameters within MODE SELECT, refer to Sections 5.9.9 (EEPROM Vendor Unique Page 3Eh) and 5.9.10 (Changeable Parameters within MODE SELECT).
