Commands for Status Monitoring and Statistics
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 failover criteria (such as node priority) and the system and
hardware health computations. You can use this information to determine which node will be elected
primary in case of a failover.
Table 11 lists the node statistic information collected by the switch.
Example
The following command displays the status of the node, the priority of the node, and the general health
of the system:
show node
detail Displays the information on a per-node basis rather than in a tabular format.
Table 11: Node states
Node State Description
INIT The initial state where 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.
OFFLINE You have requested the node to go down. Use this mode to run diagnostics or perform
software upgrades. In this mode, the node is not available to participate in leader election.
FAIL 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.
MASTER This node is the MASTER node and is responsible for all of the switch management
functions.
BACKUP This node is the designated backup (secondary) node and will be used to failover if the
primary is unavailable. This node will become the primary node. This node also receives the
checkpoints from the primary.
STANDBY This node is in the standby state.If the primary is not available, this node will enter leader
election and transition to primary if it wins. If you request a node to enter the backup state, it
will enter the standby state before entering the backup state.
