Scanning for and resolving storage failover interconnect link down conditions

Contributors netapp-adityaw

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, OnCommand 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. To check for recent availability events related to storage failover issues, check the Availability Incidents section and the Availability Risks listings on the Dashboards/Overview page.

  2. To check further for all availability events related to storage failover issues, perform the following steps:

    1. Click the Availability Incidents link on the Dashboards/Overview page.

      The Events inventory page displays all events on the monitored clusters.

    2. On the Events inventory page, select the options Incident and Risk in the Filter column.

    3. At the top of the Events inventory page Names 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.

      In this scenario, the Unified Manager displays the event, “Storage Failover Interconnect One or More Links Down” in its Availability Incidents section.

  3. If one or more events related to storage failover are displayed either on the Dashboards/Overview page or on the Events inventory page, perform the following steps:

    1. Click the event title link to display event details for that event.

      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:
