Recover from an Upgrade Failure

You can recover from an upgrade failure by rerunning the upgrade or by performing a fresh installation and then restoring the system with the backup taken at the beginning of the upgrade process.

Procedure

  1. To rerun the upgrade, follow the steps for the type of upgrade you were attempting.
  2. To perform a fresh installation and restore the system backup, take the following steps.
    1. Uninstall EFA to remove any components that might have been installed before the upgrade failed.
    2. Follow the steps for the type of installation you need.
    3. Restore the backup.
      device# efa system restore --backup-tar <filename>.tar.gz
      For more information about backup tar files, see the "Database Backup and Restoration" section of the Extreme Fabric Automation Administration Guide, 2.4.0 .
