6 Mode Sense—1Ah

Command Description

The MODE SENSE command asks the library to report its operating mode parameters to the
initiator. The parameters are returned in mode pages. The library supports the
following pages:
• Element address assignments—1Dh
• Tape picker capabilities (transport geometry parameters)—1Eh
• Device capabilities, such as where media can be moved or stored—1Fh
These pages are described in detail under Command Response on page 29. The
initiator can change some of these parameters using the MODE SELECT (15h) command.
The SPC-3 Standard provides both a 6-byte and a 10-byte MODE SENSE command. The
library uses the 6-byte command. The table below shows the CDB for the MODE SENSE
command.
