Vendor-Unique SCSI Information

Overview

Product Manual
The DAT drives provide a configuration flash memory that contains configuration
settings, the drive serial number and other data. You can reprogram some of the
configuration parameters in the flash memory using the SCSI MODE SELECT
command—MODE SELECT Flash Memory Configuration Page (30
the MODE SENSE command—MODE SENSE Flash Memory Configuration Page
(30 )—to return the values that currently reflect the drive configuration information.

When the drive is manufactured, the Configuration flash memory is initially
programmed with several factory-default settings. You can issue a MODE SELECT
command with page 30
certain options. The parameters are transferred to the drive as data formatted in a
parameter list.
Once the flash memory is programmed, the new parameters are in effect after a
power-on or SCSI reset conditions. These parameters remain valid until you
program the flash memory again with new parameters.
Where applicable, the MODE SELECT command immediately checks for invalid
parameters and if an exception is found, the drive returns a Check Condition with
the sense data set to Illegal Request.
Complementary to the MODE SELECT command, the MODE SENSE Page (30
command allows you to determine the flash-memory parameters. These parameters
are sent from the drive to the host as data formatted in a parameter list.
