SCSI Commands
Quantum DLT 4000 Tape Drive
5-81
MODE SELECT (6) / (10) Command (15h) / (55h) (continued)
Table 5–41 Device Configuration Page - Field Descriptions (continued)
Field Name
Description
Write Delay Time
(cont.)
Values between 0 and 15 on a MODE SELECT are rounded down to 0.
This causes the data to go straight to the medium without delay.
DBR
Data Buffer Recovery. Not supported, must be 0.
BIS
Block Identifiers Supported. This field is supported. Set to 1.
RSmk
Report Setmark. Not supported, must be 0.
AVC
Automatic Velocity Control. Not supported; must be 0.
SOCF
Stop on Consecutive Filemarks. Not supported; must be 0.
RBO
Recover Buffer Order. Not supported; must be 0.
REW
Report Early Warning. Not supported; must be 0 (do not report Early
Warning EOM on READ).
Gap Size
Not used; must be 0.
EOD Defined
End-of-Data Defined. This field must be set to 00h.
EEG
Enable End-of-Data Generation. Set to 1. This field indicates that the drive
will generate an EOD. The drive generates an EOD mark before any
change of direction following a WRITE-type operation. This bit is ignored,
however, on MODE SELECT.
SEW
Synchronize at Early Warning. Must be set to 1.
Buffer Size at Early
Warning
Not supported; must be 0.
SEW
Synchronize at Early Warning. Must be set to 1.
Select Data
Compression
Algorithm
When set to 1, enables data compression. When
0, disables data compression.
The setting on the front panel of the tape drive overrides any setting of
MODE SELECT, but no error will result. If the setting is returned to the
automatic mode on the front panel of the tape drive, the value from the
last MODE SELECT command determines whether compression is
enabled or disabled.
