CSCvt67719	HS1: Device stuck with rommon upgrade from 29r to 38r
CSCvu34503	ASR920/RSP2: Bundle 43r ROMMON Changes to 17.3.1

Problem Description

The routers listed in the Products Affected section will fail to boot during the upgrade to IOS XE Release 17.3.1 because of the image size increase.

The releases bundled with FPGA (0x00010039 or 0x10000007) will suspend the router during the ROMMON upgrade process.

The upgrade process will succeed if the upgrade is performed with the router in sub package mode. In order to perform a clean upgrade, follow the upgrade instructions that are provided in the Workaround/Solution section of this Field Notice.

The upgrade process will fail if the upgrade is performed with the router in consolidated binary mode. Recovery instructions are also provided in the Workaround/Solution section.

Background

Because of image size increase, the router fails to boot during upgrade and it will reboot continuously with this console message: mount package service fail.

In order to boot the IOS XE image 17.3.1 successfully, the ROMMON version 43r is needed. The latest FPGA version (0x00010040 or 0x10000008) is also needed in order to ensure that the router does not become suspended during the upgrade.

Problem Symptom

Sample error logs are provided below.

Workaround/Solution

In order to perform the upgrade to IOS-XE Release 17.3.1, you must boot the software in sub package mode. In sub package mode, the router boots without any issues, and auto-ROMMON upgrade to version 43r happens on boot.

Follow these steps in order to boot the router in sub package mode:

Copy the 17.3.1 release binary and expand it to configure packages.conf.
Set the boot variable to packages.conf and reload the router.
The auto-ROMMON upgrade to version 43r and the FPGA upgrade to latest version are completed in parallel and result in a successful upgrade to IOS XE 17.3.1

NOTE: Detailed instructions to boot the device in sub package mode are available here:
https://www.cisco.com/c/en/us/td/docs/routers/asr920/upgrade/guide/b-upgrade-3x-16x-asr920/b-upgrade-3x-16x-asr920_chapter_01.html#concept_7E5AFB3D86B64137870F69CE244BF04E

Router Recovery

If the upgrade failed because the router was not in sub package mode, the mount boot package error might cause the router to enter a contnuous system reboot state, or the ROMMON upgrade issue might cause the router to enter a suspend state. This section provides instructions to recover the router from each of these states.

Follow these steps in order to recover the router from a continuous system reboot state because of a mount boot package error:

Ensure that you are connected to the router in console mode.
After you log in, press CTRL+C in order to prevent autoboot and enter ROMMON mode.
Run the command “unset BOOT” in order to remove the existing boot variable.
Run the command “BOOT= bootflash:<Your earlier release>” [Example: asr920igp-universalk9_npe.16.09.05.SPA.bin]
Run the command “sync” in order to sync the configuration.
Run the command “reset” in order to load the earlier image.
When the system is back to the console prompt, follow the upgrade instructions above.

Follow these steps in order to recover the router from suspend state because of the ROMMON upgrade issue:

Power cycle the router.

Run the command #show platform on the router in order to see if the ROMMON upgrade was successful.
