Recover from an Upgrade Failure

You have the option to recover from an upgrade failure by rerunning the upgrade, or perform a fresh installation, and then restore the system from a backup.

  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 EFA backup.
      efa system restore --backup-tar <filename>.tar.gz
      For more information about backup tar files, see the "EFA System Backup and Restoration" section of the Extreme Fabric Automation Command Reference, 3.1.0 .
