Table F–1: The tapex Options and Option Parameters (cont.)
tapex Flag Flag and Parameter Descriptions
−q
Specifies the command timeout test. This test verifies that
the driver allows enough time for completion of long
operations. This test writes files to fill the tape. It then
performs a rewind, followed by a forward skip to the last file.
This test is successful if the forward skip operation is
completed without error.
−r
Specifies the record size test. A number of records are written
to the tape and then verified. This process is repeated over a
range of record sizes. The following parameters can be used
with the −r 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
Specifies a time limit (in minutes).
The default is to run the test until
it is complete.
−R
Specifies the record-positioning test. First, records are written
to the tape and verified. Next, every other record on the tape
is read. Then, the other records are read by traversing the
tape backwards. Finally, random numbers are generated; the
tape is positioned to those locations, and the data is verified.
The following parameters can be used with the -R flag:
−pos_num
Specifies the number of records.
−pos_ra
Specifies the number of random
repositions.
−pos_rs
Specifies the record size.
−s
Specifies the record size behavior test. Verifies that a record
that is read returns one record (at most) or the read size,
whichever is less. The following parameters can be used with
the −s flag:
−num_rec
Specifies the number of records.
−size_rec
Specifies the record size.
