Maintenance Objects

The maintenance subsystem is partitioned into separate entities called Maintenance Objects (MOs). A maintenance object can be:

• An individual Media Module
• A hardware component that is part of a Media Module
• An entire subsystem
• A set of monitors
• A process (or set of processes)
• A combination of processes and hardware

"Maintenance names" are recorded in the Error and Alarm logs. Individual copies of an MO are assigned an address that defines the MO's physical location in the system when applicable. These locations display as the port field in the Alarm and Error logs and as output of various commands such as test board.
