show node
show node {detail}
Description
Displays the status of the nodes in the system as well as the general health of the system.
Syntax Description
Default
N/A.
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.
Table 11
lists the node statistic information collected by the switch.
detail
Displays the information on a per-node basis rather than in a tabular format.

Node State
Description
BACKUP
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.
DOWN
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
reboot
command
• Initiating an MSM failover using the
run msm-failover
command
• Synchronizing the MSMs software and configuration in non-volatile storage using the
synchronize
command
FAIL
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.
INIT
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.
MASTER
In the master state, the node is responsible for all switch management functions.
STANDBY
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.
