This workflow provides an example of how you might evaluate and resolve a volume offline event that Unified Manager might display in the Availability area of the Dashboards/Overview page. In this scenario, you are an administrator using Unified Manager to troubleshoot one or more volume offline events that are displayed on the Dashboards/Overview page.
Before you begin
You must have the Operator, OnCommand Administrator, or Storage Administrator role.
About this task
Volumes might be reported offline for several reasons:
- The SVM administrator has deliberately taken the volume offline.
- The volume's hosting cluster node is down and storage failover to its HA pair partner has failed also.
- The volume's hosting storage virtual machine (SVM) is stopped because the node hosting the root volume of that SVM is down.
- The volume's hosting aggregate is down due to simultaneous failure of two RAID disks.
You can use the
Dashboards/Overview page and the
Health/Cluster,
Health/SVM, and
Health/Volume details pages to confirm or eliminate one or more of these possibilities.
Procedure
-
From the Availability panel in the Unresolved Incidents and Risks section, click the hypertext link displayed for the Volume Offline event.
The Event details page for the availability incident is displayed.
- On that page, check the notes for any indication that the SVM administrator has taken the volume in question offline.
- On the Event details page, you can review the information for one or more of the following tasks:
