4 Configuring failover

This chapter describes how to configure failover for agile management consoles, file serving nodes,
network interfaces, and HBAs.

Agile management consoles

The agile Fusion Manager maintains the cluster configuration and provides graphical and
command-line user interfaces for managing and monitoring the cluster. The agile Fusion Manager
is installed on all file serving nodes when the cluster is installed. The Fusion Manager is active on
one node, and is passive on the other nodes. This is called an agile Fusion Manager configuration.

Agile Fusion Manager modes

An agile Fusion Manager can be in one of the following modes:
active. In this mode, the Fusion Manager controls console operations. All cluster administration
and configuration commands must be run from the active Fusion Manager.
passive. In this mode, the Fusion Manager monitors the health of the active Fusion Manager.
If the active Fusion Manager fails, the a passive Fusion Manager is selected to become the
active console.
nofmfailover. In this mode, the Fusion Manager does not participate in console operations.
Use this mode for operations such as manual failover of the active Fusion Manager, IBRIX
software upgrades, and server blade replacements.
Changing the mode
Use the following command to move a Fusion Manager to passive or nofmfailover mode:
ibrix_fm -m passive | nofmfailover [-A | -h <FMLIST>]
If the Fusion Manager was previously the active console, IBRIX software will select a new active
console. A Fusion Manager currently in active mode can be moved to either passive or nofmfailover
mode. A Fusion Manager in nofmfailover mode can be moved only to passive mode.
With the exception of the local node running the active Fusion Manager, the -A option moves all
instances of the Fusion Manager to the specified mode. The -h option moves the Fusion Manager
instances in <FMLIST> to the specified mode.

Viewing information about Fusion Managers

To view mode information, use the following command:
ibrix_fm –i
NOTE: If the Fusion Manager was not installed in an agile configuration, the output will report
FusionServer: fusion manager name not set! (active, quorum is not
configured).
When a Fusion Manager is installed, it is registered in the Fusion Manager configuration. To view
a list of all registered management consoles, use the following command:
ibrix_fm –l

Agile Fusion Manager and failover

Using an agile Fusion Manager configuration provides high availability for Fusion Manager
services. If the active Fusion Manager fails, the cluster virtual interface will go down. When the
passive Fusion Manager detects that the cluster virtual interface is down, it will become the active
