TAPEX
The TAPEX program is a DFS based tape exerciser. It is intended to
be used for quick tape subsystem integrity testing as well as long
term reliability testing. To invoke the program type:
CLI> x tapex
The program will size the system and query the operator about testing
each existing tape drive which is on-line. After these questions the
exerciser will begin testing. Once testing has begun the exerciser
may be stopped by typing control-G. Any other character will cause
the program to display status information about each drive. This
status information includes the time the test was started, the current
time, total number of bytes transfered, total hard errors, total soft
errors, and data errors.
The exerciser does transfers in the following manner.
1.) Select a random data pattern and write a record of random
length. This step is repeated a random number of times
between 16 and 63.
2.) Backspace a random number of records between 1 and the number
of records just written.
3.) Read and check the data of the records just backspaced over.
These three steps are repeated for each unit with all units running in
parallel until the test is stopped.
