Deploying Software Images

This topic describes how to deploy software images to managed devices. You must upload software images to the Network Director server before you can deploy them to devices. See Managing Software Images for more information.

Procedure

To start deploying software images:

  1. Click Deploy in the Network Director banner.
  2. Select a node in the View pane that contains the devices on which you want to deploy software images.
  3. In the Tasks pane, select Image Management > Deploy Images to Devices.

    The Select Devices page of the Deploy Images to Devices wizard opens in the main window.

This topic describes:

Specifying Software Deployment Job Options

Procedure

To specify software deployment job options in the Select Devices page:

  1. In the Job name field, enter a job name.
  2. From the Device and deployment options list, select an option:
    • Select Staging only (Download image to the device) to download the software image to the device but not install it.
    • Select Upgrade only (Install previously staged image on device) to upgrade the device to a software image that was previously staged on the device.
    • Select Staging and Upgrade (Download and Install image on device) to download the software image and install it on the device.

    Devices are not automatically rebooted after upgrade to make the device begin running the new software version. You can select the option to reboot the device automatically after the upgrade in a later wizard page.

  3. Click Next to continue to the next page.

    The Select Images page opens. Select a software image as described in Selecting Software Images To Deploy.

Selecting Software Images To Deploy

The Select Images page includes a table listing each device group and device that you selected for deployment. See Table 283 for a description of the table columns.

If you selected the Upgrade only (Install previously staged image on device) option, only devices that contain a previously staged software image appear in the table. You cannot select a different image to install on these devices.

Procedure

To select the software images to deploy, perform the following steps on the table row for each device group or individual device that you want to upgrade:

  1. In the Proposed Image Version/Profile column, click Select Image/Profile.

    The Select Image/Profile list is displayed.

  2. From the Select Image/Profile list, select a software image.

    Note: To clear this field, select Select Image/Profile from the list.

  3. After you finish selecting software images, click Next to continue to the next page.

    The Select Options page opens.

    Note: A message notifies you if you do not select a software image for all the listed devices. This is just for your information. No action is taken on devices for which you do not select a software image. In effect, this removes those devices from the job.

    Select options for software deployment as described in Selecting Options for Software Deployment.
