Node1::*> system health alert show Node: Node2 Resource: Brocade_switch Severity: Major Indication Time: Mon Jul 19 14:20:35 2021 Suppress: false Acknowledge: false Probable Cause: All ISL links on Brocade_switch are down. Possible Effect: Backend fabric might lose ISL redundancy. Corrective Actions: 1) Repair the backend fabric ISLs on Brocade_switch. 2) Ensure that the peered cluster is up and running by using the command "cluster peer ping".
