Determining if a volume is offline and its SVM is stopped because a node is down

You can use the Unified Manager web UI to confirm or eliminate the possibility that a volume is offline because its host storage virtual machine (SVM) is stopped due to the node hosting the root volume of that SVM being down.

Before you begin

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

About this task

To determine if the volume offline condition is caused its host SVM being stopped because the node hosting the root volume of that SVM is down, perform the following actions:

Steps

  1. Locate and click the hypertext link displayed under SVM in the Related Devices pane of the offline volume's Health/Volume details page.
  2. Locate and click the hypertext link displayed under the SVM in the Related Devices pane of the offline volume's Health/Volume details page.
    The Health/Storage Virtual Machine details page displays the "running" or the "stopped" status of the hosting SVM. If the SVM status is running, then the volume offline condition is not caused by the node hosting the root volume of that SVM being down.
  3. If the SVM status is stopped, then click View SVMs to further identify the cause of the hosting SVM being stopped.
  4. On the Health/Storage Virtual Machines inventory page SVM column header, click the filter symbol Icon for column filter and then type the name of the stopped SVM.
    The information for that SVM is shown in a table.
  5. On theHealth/Storage Virtual Machines inventory page, click Icon for grid view and then select the option Root Volume.
    The Root Volume column is added to the SVM inventory and displays the name of the root volume of the stopped SVM.
  6. In the Root Volume column, click the name of the root volume to display the Health/Storage Virtual Machine details page for that volume.
    If the status of the SVM root volume is (Online), then the original volume offline condition is not caused because the node hosting the root volume of that SVM is down.
  7. If the status of the SVM root volume is (Offline), then locate and click the hypertext link displayed under Aggregate in the Related Devices pane of the SVM root volume's Health/Volume details page.
  8. Locate and click the hypertext link displayed under Node in the Related Devices pane of the Aggregate's Health/Aggregate details page.
    The Nodes tab on the Health/Cluster details page displays the state of the HA pair of nodes to which the SVM root volume's hosting node belongs. The state of the node is indicated in the display.

After you finish

After you confirm that the volume offline condition is caused by that volume's host SVM offline condition, which itself is caused by the node that hosts the root volume of that SVM being down, contact the appropriate administrator or operator to manually restart the down node.
