Procedure 5-7.7: Dual Image Configuration

Step

This command manages the dual images. The software on the VLNC4x/VLNC6x supports a dual image feature that allows the pack to have two images in permanent storage. You can specify which image is the active image to be loaded in subsequent reboots. This feature allows reduced down-time when you upgrade or downgrade the pack’s software.

Next-Active - Displays the image to be used on the next restart of this unit.

    The image to be deleted must be a backup image. If the image is active or activated, an error is displayed.

  • Click Boot System Image to activate the specified image. It will be loaded by the boot loader and will be the active-image for subsequent reboots. The current active-image is marked as the backup-image for subsequent reboots. If the specified image doesn’t exist on the system, this command returns error.

    Equivalent CLI command: boot system {image1 | image2}.

  • Click Update Bootcode to update the bootcode (boot loader) on the switch. The bootcode is read from the active-image for subsequent reboots. You must use this command only as part of an upgrade procedure for the pack.
