Monitoring management module redundancy

Status LED
You can determine which management module is currently active and which is standby by
observing the Active LED on each module. If this LED is on (green), the module is the active
module. If this LED is off, the module is the standby module.
You can also observe the Pwr LED on each module. If this LED is on (green), the module is receiving
power. If the LED is off, the module is not receiving power. (A module without power will not function
as either the active or standby module.)
For information about what to do if these LED indicators are not what you expect, refer to the
appropriate hardware installation guide.
Software
To display the status of the management modules using the software, enter the following
command at any level.
The Status column indicates the module status. The management module status can be one of the
following:
• ACTIVE – Current active management module
• STANDBY – Current standby management module.
The status of the standby module can be one of the following:
• Init – Currently initializing as the standby module
• Ready – Ready to take over as the active module, if necessary
• Wait – Waiting for boot information from the active management module
• Sync – Active module is currently synchronizing files on the standby module
Monitoring the status change of a module
The Brocade system now logs the status change of a module. The status change of a module is
logged when the module becomes:
• Up or Ready - The module is running or ready to run.
• Down - The module is not running normally.
Upon the status change of a module, a message is logged in the syslog memory. At the CLI level,
type the show log command to view the logged messages.
The following example displays a syslog message on an Interface Module in the Down state.
Feb 5 12:16:17:N:System: Module down in slot 1, reason REBOOTED. Error Code 0
The following example displays a syslog message on a Standby Management Module in the Down
state.
Feb 5 14:38:58:N:System: Standby Management Module was down, reason Heartbeat
Loss. Error Code 5
