Field Name

Description

 

 

 

 

 

 

 

 

PS

Parameters Savable. Not supported; must be 0.

 

 

 

Page Length

The value in this field indicates the number of bytes in the Control Mode

 

 

 

Page being transferred. The value for this byte is 0Eh.

 

 

 

DCE

Data Compression Enable. The value returned for this bit depends on the

 

 

 

current WRITE density of the tape drive:

 

 

 

 

0 = Write compression is Disabled

 

 

 

 

1 = Write compression is Enabled

 

 

 

DCC

Data Compression Capable. The value returned for this bit indicates

 

 

 

 

whether this tape drive supports data compression:

 

 

 

 

0 = Data Compression is disabled

 

 

 

 

1 = Data Compression is enabled

 

 

 

DDE

Data Decompression Enable. The value returned for this bit indicates

 

 

 

whether data decompression is enabled or not.

 

 

 

 

0 = Data Decompression is Disabled

 

 

 

 

1 = Data Decompression is Enabled

 

 

 

 

Note that when the tape drive reads compressed data from tape, it

 

 

 

 

automatically decompresses the data before sending it to the initiator.

 

 

 

The value for this bit, therefore, is always 1.

 

 

 

RED

Report Exception on Decompression. The tape drive does not report

 

 

 

 

exceptions on decompression (boundaries between compressed and

 

 

 

decompressed data). The value returned for RED is 00h.

 

 

 

Compression

The value for this field is 10h. This indicates the Lempel-Ziv high

 

 

 

Algorithm

efficiency data compression algorithm.

 

 

 

Decompression

The value for this field is 10h. This indicates the Lempel-Ziv high

 

 

 

Algorithm

efficiency data decompression algorithm. If EEPROM parameter

 

 

 

 

EnaRepDCcomp is set, a value of 0 is reported if the last block read is not

 

 

 

decompressed.
