14.5 Setting a Connection Path as Up or Down

When a path’s status is Up, it is available to serve as the primary path or as a failover path between the server and the storage device. A connection path’s status might be Down because a component along the path has failed. You might specify a functioning path as Down to perform maintenance on components in a path.

You can also designate a path as Down if you want to remove the path from consideration as a failover path. For example, if multiple adapters in the server are connected to a target hardware device consisting of multiple devices, NSS would see multiple paths to the devices through each adapter. You might want to allocate which adapter serves which device. To accomplish this, you could down the paths you want the server to ignore.

  1. In iManager, click Storage > Devices.

    For instructions, see Section 9.1.3, Accessing Roles and Tasks in iManager.

  2. Select a server to manage.

    For instructions, see Section 9.1.4, Selecting a Server to Manage.

  3. In the Devices list, select a device to manage.

    Wait for the page to refresh before continuing.

  4. Click Multipath.

    This opens the Multipath page. All of the paths available between the selected server and the selected device appear in the Failover Device Paths list.

  5. Select a path to manage.

    Wait for the page to refresh before continuing.

  6. Select one of the following:

    • Up: Make the path available to be selected as the primary path or as one of the failover device paths. If the selected path is already up, this option is dimmed.

    • Down: Make the path unavailable to be selected as the primary path or as one of the failover device paths. If the selected path is already down, this option is dimmed.
