Troubleshooting Unified ISSU Problems

If the unified ISSU procedure stops progressing, complete the following steps:

1. Open a new session on the master Routing Engine and issue the request system software abort in-service-upgrade command.
2. Check the existing router session to verify that the upgrade has been aborted.

   An “ISSU: aborted!” message is provided. Additional system messages provide you with information about where the upgrade stopped and recommendations for the next step to take.

For more information about the request system software abort in-service-upgrade command, see the JUNOS System Basics and Services Command Reference.
