The Device Configuration Page controls the drive’s behavior on the SCSI
bus and allows an initiator to tune bus performance.

Compression
Algorithm
The Compression Algorithm field indicates
which compression algorithm the tape drive will
use to process data from the initiator when the
DCE bit (byte 02, bit 7) is set to 1. The only value
currently supported for this field is 10h.
NOTE: Specifying a value other than 10h for this
field causes the tape drive to return CHECK
CONDITION status, sense key set to ILLEGAL
REQUEST. However, if EEPROM parameter
EnaRepDecomp is set, the parameter in this field
is ignored and no CHECK CONDITION status is
returned.
Decompression
Algorithm
The Decompression Algorithm field indicates
which decompression algorithm the tape drive
will use when decompressing data on the tape.
The only value currently supported is 10h.
NOTE: Specifying a value other than 10h for this
field causes the tape drive to return CHECK
CONDITION status, sense key set to ILLEGAL
REQUEST.
