SMDMON - an interactive monitor for the storage Module
Drive (SMD) Controller.
PARAMETERS:
SMDMON has no parameters.
DESCRIPTION:
SMDMON is a diagnostic tool useful for troubleshooting
and executing custom tests. For maximum utility, it
requires knowledge of the host interface. Refer to the
INTRODUCTION TO SMD DIAGNOSTICS for a brief description
of the SMD Controller interface. More detailed infor-
mation is included in Section 5.
The user interacts with SMDMON

SMDMON begins with a start-up sequence similar but not
identical to the other diagnostics. The differences
are:
1) SMDMON issues a warning, but does not abort if an
error occurs during the start-up seqeunce.
2) SMDMON is based on the use of four disk units.
Therefore, it issues the SELECT and SIZE commands
to all four units and keeps a table of the drive
size parameters for all four· units.
3) SMDMON does not issue the SEEK to CY = -1 to any
drives during start-up.
After SMDMON has gone through its start-up procedure,
it prompts with: Command? SMDMON accepts and executes
command lines until the user enters the QUIT command. A
HELP command is included, which displays the command
names and parameters.
To enter command lines to SMDMON, the user must know
