Scanning for and resolving storage failover interconnect link down conditions

This workflow provides an example of how you might scan for, evaluate, and resolve downed storage failover interconnect link conditions. In this scenario, you are an administrator using Unified Manager to scan for storage failover risks before starting an ONTAP version upgrade on your nodes.

Before you begin

You must have the Operator, Application Administrator, or Storage Administrator role.

About this task

If storage failover interconnections between HA pair nodes fail during a nondisruptive upgrade attempt, the upgrade fails. Therefore, common practice is for the administrator to monitor and confirm storage failover reliability on the cluster nodes targeted for upgrade before the start of an upgrade.

Steps

  1. In the left navigation pane, click Event Management.
  2. In the Event Management inventory page, select Active Availability events.
  3. At the top of the Event Management inventory page Name column, click Icon for column filter and enter *failover in the text box to limit the event to display to storage failover-related events.
    All past events related to storage failover conditions are displayed.
    Example
    In this scenario, the Unified Manager displays the event, "Storage Failover Interconnect One or More Links Down" in its Availability Incidents section.
  4. If one or more events related to storage failover are displayed on the Event Management inventory page, perform the following steps:
    1. Click the event title link to display event details for that event.
      Example
      In this example, you click the event title "Storage Failover Interconnect One or More Links Down".
      The Event details page for that event is displayed.
    2. On the Event details page, you can perform one or more of the following tasks:
