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

In certain circumstances, you may want to perform maintenance operations on the initiators in your datacenter. For example, you may want to upgrade the firmware that has been installed on one or more initiators. In such situations, you may want to temporarily disable the Dynamic Multipathing (DMP) paths that connect these initiators to the storage, and re-enable these paths after the maintenance operations are completed. When you temporarily disable the DMP paths on an initiator, the communication to the storage is maintained through an alternative path.

Veritas Operations Manager lets you disable the DMP paths by choosing specific initiators.

To disable the DMP paths on an initiator

  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 > Hosts. In the Hosts list page, click on a host, and click Adapter tab. Select the required initiator from the Initiator table, and click Actions > Veritas DMP Maintenance.

  2. In the Start panel, and enter the required information. Click Next.

    See Start panel options for disabling DMP paths.

  3. In the Select Host(s) panel, select one or more hosts that contain the initiator. Click Next.

    See Select Host(s) panel options for disabling the DMP paths on an initiator.

  4. In the Select Initiators panel, select one or more initiators that contain the DMP paths that you want to disable.

    See Select Initiators panel options for disabling the DMP paths on an initiator.

  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 storage 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 or the array adapter maintenance operations are completed, click Next.

    See Paths Disabled panel options for disabling DMP paths.
