DISKX

The DISKX program is a DFS based disk exerciser.  It is intended to
be used for quick disk subsystem integrity testing as well as long
term reliability testing.  To invoke the program type:

    CLI> x diskx

The program will size the system and query the operator about testing
each existing disk.  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 current
head location.

The exerciser does transfers in the following manner.

    1.) write random data to a random block in the diagnostic region.
    2.) check the data just written.
    3.) read a random block from anywhere on the disk.

These three steps are repeated for each unit with all units running in
parallel until the test is stopped.
