13 entries were displayed.- The following health alerts are logged
cluster::> system health alert show
Node: node01
Resource: node01
Severity: Major
Indication Time: Mon Oct 07 13:19:08 2019
Suppress: false
Acknowledge: false
Probable Cause: One or more nodes are not connected to both cluster switches.
Possible Effect: If one cluster switch fails, "node01" might lose access to the cluster.
Corrective Actions: Ensure the switch "switch02" is connected to the node "node01".
Node: node01
Resource: node02
Severity: Major
Indication Time: Mon Oct 07 13:19:08 2019
Suppress: false
Acknowledge: false
Probable Cause: One or more nodes are not connected to both cluster switches.
Possible Effect: If one cluster switch fails, "node02" might lose access to the cluster.
Corrective Actions: Ensure the switch "switch01" is connected to the node "node02".

cluster::> system health alert show
Node: cluster-01
Resource: Ethernet1/1
Severity: Minor
Indication Time: Wed Aug 25 05:23:27 2021
Suppress: false
Acknowledge: false
Probable Cause: MTU value "1500" on port "e0e" of node
"cluster-01" is improperly set. It
should be 9000.
Possible Effect: Received Ethernet packets that are larger than the
configured MTU are dropped, causing data transfer
issues.
Corrective Actions: modify the MTU using the command "network port
broadcast-domain modify -ipspace Cluster
-broadcast-domain Cluster -mtu <MTU>". To find out the
broadcast domain name of the port, execute the command
"network port broadcast-domain show".
