In addition to showing information about testable device options, MDM
displays messages indicating the presence of nontestable system devices.
If a device is in your system but is not listed in the System Configuration
and Devices display, one of the following two messages can indicate the
reason.
No Dg xxx ... Diagnostic not loaded
MDM displays a No Dg (no diagnostic) message for each nontestable
Digital device in your system, where xxx indicates the device. For
example, if MDM cannot find the TK70 tape drive diagnostic, the
message No Dg TKA is displayed. TKA indicates that the device is a
TK tape drive. Such a message can appear when:
The medium is not installed properly.
The diagnostic is not on the medium.
Unknown ... Diagnostic not loaded
The Unknown (unknown device) message indicates that a device not
recognized by MDM is attached to your system. That message appears
when:
A device is configured to a nonstandard CSR address.
A Digital device that has no diagnostic is attached to your system.
That can occur if a device not supported on your system is attached.
A non-Digital device is attached to your system.
After all devices are listed, you can return to the Main Menu by pressing
Return
.
From the Main Menu you can exit MDM as described in Section 3.6 or you
can select one of the other options.
