Running the Diagnostic Monitor
The MicroVAX Diagnostic Monitor (MDM) is an optional software package
containing diagnostic tests that isolate and identify faults in your system.
MDM also lets you display your system configuration and test how devices
work together.
MDM is on tape, in a cartridge labeled MV DIAG CUST TK50. MDM
operating instructions begin in Section 2.2.
CAUTION
If your system is connected to a cluster, notify your cluster manager
before halting the system to load MDM.
You generally run MDM in four situations:
• Before you install software on a new system
• After you add a device to your system
• After you receive an error message or experience a system problem
• When you want to test your system periodically to ensure that all
components are operating correctly
