Server Alarms - Avaya Support

Server Alarms
ARB (Arbiter)
The Arbiter process runs on S8700-series servers to:
● Decide which server is healthier and more able to be active
● Coordinate data shadowing between servers under the Duplication Manager’s control
At the physical and data-link layers, three links may serve as redundant inter-arbiter UDP
communication paths: the control network A link, the control network B link (if present), or an
Ethernet-based duplication link. Two of these links must be present. The redundant inter-arbiter
UDP communication paths are used to:
● Enable arbitration between the active and standby servers
● Provide the necessary status signaling for memory refreshes
All inter-arbiter communication links use triple DES encryption for secure communication and
control.
Table 5: ARB Alarms describes the Arbiter’s alarms and their troubleshooting procedures. See
DUP (Duplication Manager) for more information.
