Other Diagnostic Commands - (A= Control Key)
"CR"
M
0
Type a "RETURN" to continue the program after it is
locked in a switch modification mode.
This command, given at any time, resets "SWREG" to
default mode and restart the program.
This command, given at any time, restarts the
program. Switches are left with the values they had
before the command was issued.
This command, given at any time, causes the program
control to go to ODT (this is an optional command and
available only if ODTPK is present).
This command, given at any time prints the current
operating modes.
This command, given at any time, locks the program
into switch modification mode where more than one bit can
be changed.
4.7.5 Diagnostic Program Tests - The diagnostic program tests the
logic, control, firmware, etc. of the disk controller and functioning
(seek, read, write, recalibrate) of the drive attached to the subsystem.
The diagnostic program is a progressive series of individual tests. In
general, each test assumes that previous logic and function tests passed
without error. The test complexity usually increases with test
progression.
In general, each successive test assumes all previous test>s work.
Bypassing errors can result in confusing situations in the setup of
more complex tests.
