tapex Flag Flag and Parameter Descriptions
−j
Specifies the write phase of the tape-transportability tests.
This test writes a number of files to the tape and then
verifies the tape. After the tape has been successfully
verified, it is brought off line, moved to another tape unit,
and read in with the −k flag. This test proves that you can
write to a tape on one drive and read from a tape on another
drive. The −j flag is used with the −k flag. Note the −j flag
and the −k flag must use the same parameters. The following
parameters can be used with the −j and −k flags:
−tran_file
Specifies the number of files to
write or read.
−tran_rec
Specifies the number of records
contained in each file.
−tran_rs
Specifies the size of each record.
−k
Specifies the read phase of the tape-transportability tests.
This test reads a tape that was written by the −j test and
verifies that the expected data is read from the tape. This test
proves that you can write to a tape on one drive and read
from a tape on another drive. As stated in the description of
the −j flag, any parameters specified with the −j flag must be
specified with the −k flag. (See the description of the −j flag
for information on the parameters that apply to the −j and
−k flags.)
−L
Specifies the media loader test. For sequential stack loaders,
the media is loaded, written to, and verified. Then, the media
is unloaded, and the test is run on the next piece of media.
This verifies that all of the media in the input deck can be
written to. To run this test in read-only mode, also specify the
−w flag.
−l
Specifies the EOF test. This test verifies that a zero byte
count is returned when a tape mark is read and that an
additional read fetches the first record of the next tape file.
−m
Displays tape contents. This is not a test. This flag reads the
tape sequentially and prints out the number of files on the
tape, the number of records in each file, and the size of the
records within the file. The contents of the tape records are
not examined.
−o filename
Sends output to the specified file name. The default sends
output to the terminal screen.
−p
Runs both the record-positioning and file-positioning tests.
For more information, refer to descriptions of the −R and −F
flags.
