Device Status (3Eh) Log Page Parameter — Field Descriptions
Field Name
Description
Parameter Control Byte – DU, DS, TSD, ETC, TMC, and LP are collectively referred to as the Parameter
Control Byte.
DU
Disable Update. This bit is always 0.
DS
Disable Save. Since the tape drive does not support
saving parameters, this bit is always 1.
TSD
Target Save Disable. Since the tape drive does not
support saving parameters, this bit is always 1.
ETC
Enable Threshold Comparison. The tape drive does not
support Threshold Checking on this page. This bit is
always 0.
TMC
Threshold Met Criteria. This bit is always 0.
LP
List Parameter. This bit is always 0 since the tape drive
treats the parameter codes as data counters.
Parameter Code
(0000h)
This parameter specifies the device type. For sequential type devices, the
parameter value is always (00 01 00 00h).
Parameter Code
(0001h)
This parameter specifies the tape drive cleaning related status. There are three bits
currently defined in this parameter.
