Displays the status of the nodes in the system as well as the general health of the system.

Syntax Description

Usage Guidelines

Use this command to display the current status of the nodes and the health of the system. The

information displayed shows the node configurations (such as node priority) and the system and

hardware health computations. You can use this information to determine which node will be elected

master in case of a failover.

lists the node statistic information collected by the switch.

Table 11: Node states

In the backup state, this node becomes the master node if the master fails or enters the

DOWN state. The backup node also receives the checkpoint state data from the master.

In the down state, the node is not available to participate in leader election. The node enters

this state during any user action, other than a failure, that makes the node unavailable for

management. Examples of user actions are:

• Upgrading the software

• Rebooting the system using the

• Initiating an MSM failover using the

• Synchronizing the MSMs software and configuration in non-volatile storage using the

In the fail state, the node has failed and needs to be restarted or repaired. The node reaches

this state if the system has a hardware or software failure.

In the initial state, the node is being initialized. A node stays in this state when it is coming

up and remains in this state until it has been fully initialized. Being fully initialized means

that all of the hardware has been initialized correctly and there are no diagnostic faults.

In the master state, the node is responsible for all switch management functions.

In the standby state, leader election occurs—the master and backup nodes are elected. The

priority of the node is only significant in the standby state.
