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.
-param <
param_spec>
Specifies new values for the tape drive data block size and/or the tape device driver debug
level. You must provide a -param <param_spec> argument except when using the -help
argument.
The -param <param_spec> argument comprises a two-element specification ordered as
follows: -param :blksize:dbglevel:. 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.
