Ethernet Switch Health Monitor (CSHM) AutoSupport message

Issue

Ethernet Switch Health Monitor (CSHM) AutoSupport message was triggered by an Ethernet switch error condition.
Active alerts can be displayed by running the command: system health alert show -monitor ethernet-switch

Cause

Monitoring the health of your system

Health monitors proactively monitor certain critical conditions in your ONTAP cluster and raise alerts if they detect a fault or risk.
If there are active alerts, the system health status reports a degraded status for the cluster.
The alerts include the information that you need to respond to degraded system health.

Solution

Identify the Alert ID by running the command: system health alert show -monitor ethernet-switch -instance

Example

::> system health alert show -monitor ethernet-switch -instance

Node: node1

Alert ID: UnsupportedSwitch_Alert

Alerting Resource: sw1(XXXXX)

Severity: Major

Indication Time: Wed Feb 25 21:27:48 2015

Suppress: false

Acknowledge: false

...

   Possible Effect: Communication problems and network connectivity issues occur.

        Corrective Actions: Unsupported Ethernet switch

                            "sw1(XXXXX)" found. Connect

                            a supported Ethernet switch to the network.
