tapex Flag Flag and Parameter Descriptions
−S
Specifies single record size test. This test modifies the record
size test (the −r flag) to use a single record size. The
following parameters can be used with the -S flag:
−inc
Specifies the record increment
factor.
−max_rs
Specifies the maximum record size.
−min_rs
Specifies the minimum record size.
−num_rec
Specifies the number of records.
−T
Displays output to the terminal screen. This flag is useful if
you want to log output to a file with the −o flag and also have
the output displayed on your terminal screen. This flag must
be specified after the −o flag in the command line.
−v
Specifies verbose mode. This flag causes detailed information
to be output. For example, it lists the operations the exerciser
is performing (such as record counts), and detailed error
information. Information provided by this flag can be useful
for debugging purposes.
−V
Specifies enhanced verbose mode. This flag causes output of
more detailed information than the −v flag. The additional
output consists of status information on exerciser operations.
Information provided by this flag can be useful for debugging
purposes.
−w
Opens the tape as read-only. This mode is useful only for
tests that do not write to the media. For example, it allows
the −m test to be run on a write-protected media.
−Z
Initializes the read buffer to the nonzero value 0130. This can
be useful for debugging purposes. If the −Z flag is not
specified, all elements of the read buffer are initialized to
zero. Many of the tests first initialize their read buffer and
then perform the read operation. After reading a record from
the tape, some tests validate that the unused portions of the
read buffer remain at the value to which they were
initialized. For debugging purposes, you can set this
initialized value to a number other than zero. In this case,
you can use the arbitrary value 0130.
The following example runs an extensive series of tests on tape device
rmt1h and sends all output to the tapex.out file:
# tapex −f /dev/rmt1h -E -o tapex.out
