Installing a JUNOS Software Image

You can save an install software image operation so that you can combine it with other operations or run it at a later time.

To install a JUNOS software image and save an install software image operation, follow these steps:

1. In the JUNOScope main window, click Software Management > Images.

   The Images dialog box appears.

   
2. Click the Install link for the JUNOS software image that you want to install.

   The Install Image dialog box appears.

   
3. Select the installation option(s) that you want.
   • Use Image Already Downloaded Onto Device—Installs an image that has already been downloaded to the /var/tmp directory of a device.
   • Archive Data And Executable Areas (Snapshot)—(Default) This option is the equivalent of the JUNOS software request system snapshot command. The command backs up the currently running and active file system partitions on the router to standby partitions that are not running. Specifically, the root file system (/) is backed up to /altroot, and /config is backed up to /altconfig. The root and /config file systems are on the router’s flash drive, and the /altroot and /altconfig file systems are on the router’s hard drive. After you run the request system snapshot command, you cannot return to the previous version of the software, because the running and backup copies of the software are identical.

     The request system snapshot command can fail on J-series devices when there is no compact flash to back up the system.

   • Load Succeeds If At Least One Statement Is Valid —Activates a partial load and treats parsing errors as warnings instead of errors. Even if some of the statements (but not all) are invalid, the software installation succeeds. This option is the equivalent of using the request system software add <image> best-effort-load CLI command.
   • Remove The Package After Successful Installation—Allows the system to find enough room to upgrade a new software image. Use this option when installing a software image from a local directory on a device that has minimal storage space. This command is equivalent to the request system software add uplink CLI command.
4. Select the Group or Select Device(s) option button.
5. Select the group or devices that you want from the Group or Select Device(s) list box. Shift+click to select multiple devices from the Select Device(s) drop-down list box.

   Note: When you have selected a JUNOS image for installation, only JUNOS devices are listed in the list of devices. If you choose a device group that contains devices that run operating systems other than JUNOS, the Status page shows “Operation Not Supported” status for such devices.

6. In the Comment text box, type an optional descriptive comment about the software image installation operation.
7. Select when you want the software image installation to occur and to save the operation by clicking the appropriate option button:
   • Now—(Default) Performs a software image installation immediately after you confirm it.
   • Save Operation as—Saves the current operation in the Settings > Saved Operations table so you can combine that operation with other JUNOScope operations or run that operation at a later time. Click the Save Operation as option button, then type an operation name in the text box.
   • Select Schedule—Performs a software image installation at the scheduled time interval. Select the Select Schedule option, then select the schedule that you want in the schedule table.
8. Click Next.
   • If you selected the Now option, the Please Confirm—Install Image dialog box appears.
   • If you selected the Save Operation as option, the Please Confirm—Save Install Image dialog box appears.
9. Confirm that the software image install options that you selected are correct.
10. Click Finish to confirm the software image install operation that you specified.
    • If you selected the Now option, software image installation occurs immediately.
    • If you selected the Save Operation as option, the operation is saved in the Settings > Saved Operations table. To view the saved operation, click Settings > Saved Operations. For more information about managing saved JUNOScope operations, see Using Task Manager (Saved Operations).
    • If you selected the Select Schedule option, the software image installation occurs when the operation is scheduled to be run.

      When the software image install process is complete, the Status—View Status Records dialog box appears.

      

      The Status—View Status Records dialog box lists the software image download operation by operation name, operation type, report name, username, operation status, last updated time, and operation system log message. The Archive operation status can be successful, failed, writing, pending, connecting, or working.

      The Software Manager reboots the device after the software is installed.

      

      After the device reboots, connection must be reestablished with the device. If connection is not established within a specified time, a “ could not open connection” error message appears in the View Status Records dialog box table.

      If connection is not established with the device it may because of one of the following reasons, and you may have to install the software manually:

      • The request system snapshot command may not work on some devices.
      • There may not be enough available disk space on the device.
      • The newly installed software may not be compatible with the existing configuration.
      • The newly installed software may not be compatible with the Physical Interface Cards (PICs) that are installed on the device.
11. Click OK.
