Disabling the DMP paths on an array using Veritas Operations Manager 5.0

In certain circumstances, you may want to perform maintenance operations on the array ports or array adapters in your datacenter. For example, you may want to upgrade the firmware that has been installed on the array adapter. In such a situation, you may want to temporarily disable the DMP paths that connect this array adapter to the storage, and re-enable these paths after the maintenance operations are completed. When you temporarily disable the DMP paths on an array port or an array adapter, the communication to the storage is maintained through an alternative path.

Veritas Operations Manager lets you disable the DMP paths by choosing specific arrays in your datacenter.

To disable the DMP paths on an array

  1. In the Veritas Operations Manager console, do one of the following:

    • Select Solutions to go the Solutions page. Under Veritas DMP Maintenance, click Start new Veritas DMP Maintenance case.

    • Select Manage > Enclosures. In the Enclosures list page, select an enclosure and click Actions > Veritas DMP Maintenance.

  2. In the Start panel, ensure that Array is selected, and enter the required information. Click Next.

    See Start panel options for disabling DMP paths.

  3. In the Select Enclosure wizard panel, choose the enclosure that contains the array port or the array adapter on which you want to perform maintenance. Click Next.

    See Select Enclosure panel options for disabling the DMP paths on an array.

  4. In the Specify Array Port(s) wizard panel, choose the array port or the array adapter that contains the ports on which you want to perform maintenance. You can choose from array adapters only if the Veritas Operations Manager Storage Insight Add-on is configured for the selected array.

    See Specify Array Port(s) panel options for disabling DMP paths.

  5. In the Path Disable Confirmation panel, review the details of the DMP paths. To view the information on the relationship of the DMP paths with other resources in your datacenter, click View Associations Report.

    See Path Disable Confirmation panel options for disabling the DMP paths on an array.

    See Veritas DMP Maintenance Associations Report for understanding the relationship between the DMP paths to be disabled and other datacenter resources

  6. In the Path Disable Confirmation panel, click Disable to disable all the listed DMP paths.

    See Path Disable Confirmation panel options for disabling the DMP paths on an array.

  7. In the Paths Disabled panel, review the details of the disabled paths and the commands that were run to complete the operation. Do one of the following:

    • To save and close the configuration and re-enable the DMP paths later, click Save&Close. If you choose this option, you can re-enable the DMP paths later using the options available on the Solutions page, or using the Unfinished Cases drop-down in the Start wizard panel.

    • To re-enable the DMP paths after the array port or the array adapter maintenance operations are completed, click Next.

    See Paths Disabled panel options for disabling DMP paths.
