SYNOPSIS
dd2_set_drive -setdrv <drive_spec> [ -f <device_special_file> ]
dd2_set_drive -help [ help_type ]
DESCRIPTION
dd2_set_drive changes the tape drive configuration parameters to the values specified. To
view the current settings, use the dd2_query_drive utility.
OPTIONS
-f < device_special_file >
Specifies the device special file to use for the operation (see Appendix B).
ARGUMENTS
-help [ help_type ]
Displays help on stderr and invalidates all other options, cancelling any other actions. Valid
keywords for the optional help_type specification are: stdout, revision, and v_revision.
-setdrv <
drive_spec>
Specifies new values for the tape drive configuration parameters you want to change. You must
provide a -setdrv <drive_spec> argument except when using the -help argument.
The -setdrv <drive_spec> argument comprises a ten-element specification ordered as
follows: -setdrv
:tdconfig:rdretry:wrretry:wrfull:rdempty:wrdelay:sctime:thtime:ewoffset:clntime:. Each
element must be delineated by colons and included in the specification even if left empty (a
space between colons is not considered empty).
When an element is left empty the corresponding drive configuration parameter is not
changed. Valid parameters for the elements are listed below; see the
dstio.h header file for
additional details.
