High Availability overview
High-Availability (HA) features provide maximum reliability and nondisruptive replacement of key
hardware and software modules. High Availability is available only on the Brocade DCX, DCX-4S,
DCX 8510-4 and DCX 8510-8 platforms. Refer to the Fabric OS Administrator’s Guide for additional
information about High Availability.
The High Availability window, as shown in Figure 10, displays information about the status of the HA
feature on each control processor (CP), and enables you to perform CP failover.
The background color of the HA button indicates the overall status of high availability on the switch.
The colors and their meanings are:
• Green—Healthy: HA Status is HA enabled, Heartbeat Up, HA State synchronized.
• Yellow—Disruptive mode: HA Status is HA enabled, Heartbeat Up, HA State not in sync.
• Red—HA is unavailable: HA Status is Non-Redundant.
