4.9 MODE SELECT (6) / (10) Command (15h / 55h)
The MODE SELECT commands enable the host to configure the SDLT tape 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 which 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 host
passes the Mode Parameter List (described in “Mode Parameter List” on page 4-69) to the drive during
the command’s DATA OUT phase.
Operating parameters for the drive are contained in several pages. The following table lists the MODE
SELECT pages supported and the location of the sections in this manual detailing each page:
Except for the EEPROM Vendor Specific Page (page 3Eh), the drive always powers on with its default
configurations set. This is also true if the drive receives a TARGET RESET message or a reset on the
RST line of the SCSI bus.
NOTE: See “Changeable Parameters Within MODE SELECT” on page 4-105 for
a list of changeable parameters within MODE SELECT. See “EEPROM
Vendor Specific Page (3Eh)” on page 4-134 for additional information
about how to use these changeable parameters.
