Field Name

Description

 

 

DU

Disable Update. Always 0.

DS

Disable Save. Not supported. This bit always set to 1.

TSD

Target Save Disable. Not supported. This bit always set to 1.

ETC

Enable Threshold Comparison. Threshold checking is not supported on

 

this page. Always set to 0.

TMC

Threshold Met Criteria. Always 0.

LP

List Parameter. Always set to 0 (parameter codes treated as data counter).

Counter Value

Parameter Codes 02h through 09h provide a count of the number of

 

bytes transferred since the current tape cartridge was inserted or since the

 

last time the counters were reset via a MODE SELECT command.

 

Parameter Codes 02h and 03h -- Report the count of bytes transferred

 

from the tape drive to the initiator. Parameter Code 02h reports the

 

number of full megabytes transferred; Parameter Code 03h reports the

 

number of bytes less than a full megabyte that have been transferred.

 

Multiplying the counter returned for Parameter Code 02h by 1,048,576

 

and then adding the value of the counter returned by Parameter Code

 

03h results in the actual total bytes transferred to the initiator.

 

Parameter Codes 04h and 05h -- Report the count of bytes transferred

 

from the tape drive to the buffer. Parameter Code 04h reports the number

 

of full megabytes transferred; Parameter Code 05h reports the number of

 

bytes less than a full megabyte that have been transferred. Multiplying

 

the counter returned for Parameter Code 04h by 1,048,576 and then

 

adding the value of the counter returned by Parameter Code 05h results

 

in the actual total bytes transferred from tape to the buffer.
