Troubleshoot IOS XR Setup and Upgrade

Handle boot loops after an upgrade

After an upgrade using a customized GISO image containing updated SMUs and a base ISO image, you may encounter persistent boot loops on ASR 9000 line cards.

A software synchronization resolves the issue.

Procedure


Execute the hw-module location <location> bootmedia network reload command to enforce software synchronization.

Example:

Router# hw-module location all bootmedia network reload
Router# hw-module location 0/0/CPU0 bootmedia network reload

Note

 

Make sure that you enable the fpd auto-upgrade command for a successful sofware synchronization.
