Administering High Availability
High-Availability (HA) features provide maximum reliability and nondisruptive replacement of key
hardware and software modules.
The procedures in this section apply only to the SilkWorm 24000 and 48000 directors, because the High
Availability module is available only on these switch types. See the Fabric OS Administrator’s Guide
for additional information about High Availability.
The High Availability module (see Figure 3-6 on page 3-17) displays information about the status of
the HA feature on the SilkWorm 24000 and 48000 directors and each CP, and enables you to perform
CP failover.
The background color of the Hi Avail button indicates the overall status of high availability on the
switch. The colors and their meanings are as follows:
• Green—Healthy: HA Status is “Non-Disruptive Failover Ready”
• Yellow—Disruptive mode HA Status is “Disruptive Failover Ready”
• Red—HA is unavailable: HA Status is “Non-Redundant”
Admin Domain considerations: HA is possible if the switch is a member of the current Admin
Domain. If switch is not a member of current Admin Domain, Synchronize Services and Initiate
Failover buttons will be grayed out.
Launching the High Availability Module
Admin Domain considerations: To launch the Hi Avail module, the switch has to be a member of the
Admin Domain you are currently logged in to. If the switch is not a member of the current Admin
Domain, Synchronized Services and Initiate Failover will be disabled.
To launch the High Availability module
1. Select a SilkWorm 24000 or 48000 director from the Fabric Tree.
The selected director appears in the Switch View.
