Dell NetWorker 19.9 Administration Guide

Creating an AFTD by using the Device Wizard

1. In the NMC Enterprise view, double-click the NetWorker managed application to launch its window.
2. In the NetWorker Administration window, select the Devices view.
3. Verify that the path to the storage directory that will contain the AFTDs is allowed.
   1. In the navigation tree, select Storage Nodes.
   2. Right-click the storage node that you will use, and select Properties.
   3. In the AFTD allowed directories list, verify or type the path of the storage directory that will contain the AFTDs.

      AFTDs can be created and accessed only by these listed paths. If this list is left empty, there are few restrictions as to where a device path can be created.

   4. Click OK.
4. In the navigation tree, right-click Devices, and select New Device Wizard.
5. In the Select the Device Type window, select AFTD and click Next.
6. In the Select Storage Node window, specify the path to the storage directory that will contain the AFTDs.
   1. In the Storage Node list, select the storage node that you will use.
   2. If the directory for the intended AFTDs is on a different storage node or a remote storage system, select Device storage is remote from this Storage Node and type the Network Path of the remote host directory that will contain the devices.

      For example, if the storage node is a Microsoft Windows system and you use a CIFS AFTD on a remote storage system host, this path could be something like the following:

      \\dzone1_storhost2.lss.corp.com\share-1

      This storage path is not a device. It is the directory location in which the shared devices are to be created.

7. In Browse or Manual, select which option you will use to specify the pathnames of the devices:

   • Browse Storage Node or network path. The next wizard step will prompt you to browse and add the devices.

   • Manually enter local or remote device paths. Select this to skip the browse step and manually type unique names for the devices you want to add:

     • For remote devices, type the device paths relative to the Network Path that you specified for the storage directory. For example:

       cifsaftd-1

       cifsaftd-2

     • For local devices, type the absolute paths to these devices. For example:

       C:\cifsaftd-1

       C:\cifsaftd-2

       Multiple devices for a single volume configuration provides details for shared volumes.

8. If the storage host is remote from the storage node, in the Authentication area, type the appropriate Username and Password to access the storage directory.
9. Click Next.
10. If you selected the Browse option in the previous window:
    1. In the Select the Device Path window, verify that the storage node shows the path of a storage directory.
    2. Add devices to the storage directory by clicking New Folder and typing unique device names. For example:

       cifsaftd-1

       cifsaftd-2

    3. Select the new devices to add and click Next.
11. In the Configure Device Attributes window, specify the attributes. If you added multiple devices in the previous window, select each device individually and specify its attributes:
    1. In NetWorker Device Name, type a unique name for the AFTD device.

       For example, for a device on the NetWorker server host storage node: 
aftd-1

       If you configure the device on a storage node host that is not the NetWorker server host, it is a “remote device” and this attribute must be specified with rd= and a colon (:) in the following format (for Microsoft Windows):

       rd=remote_storagenode_hostname:device_name

       For example:
rd=dzone1_storhost2:aftd-1

    2. (Optional) Add a comment in the Comment field.
    3. If Client Direct backup will be used, follow the details in Considerations for Client Direct clients.
    4. In Target Sessions specify the number of sessions that a nsrmmd data mover process on the device will handle before another device on the host will take the additional sessions. Use this setting to balance the sessions among nsrmmd processes.

       If another device is not available, then another nsrmmd process on the same device will take the additional sessions.

       Typically, set this attribute to a low value. The default value is 4 for AFTDs. It may not be set to a value greater than 60.

    5. In Max Sessions specify the maximum number sessions the device may handle. If no additional devices are available on the host, then another available storage host takes the additional sessions, or retries are tried until sessions become available.

       The default value is 32 for AFTDs, which typically provides best performance. It cannot be set to a value greater than 60.

       NOTE:The Max Sessions setting does not apply to concurrent recover sessions.
    6. Click Next.
12. In the Label and Mount device window, if you select the Label and Mount option, specify the attributes for:
    • Pool Type.
    • Pool to use.
13. On the Review the Device Configuration page:
    1. Review the settings.
    2. Click Configure.
14. On the Check results page:
    1. Review whether the devices were successfully configured or if any messages appeared.
    2. Click Finish.
    3. To change any of the settings, click Back to the correct wizard page.
