Prerequisites to Disaster Recovery

The root cause of the EMS server crash needs to be identified, and the offending hardware replaced (e.g. the failed hard drive). When the server is operational, use the following procedures to recover the EMS.

When rebuilding the EMS server, make sure that the new configuration matches the configuration of the original EMS server when it crashed, paying particular attention to the server Internet Protocol (IP) address and Hostname to ensure they are identical to those on the crashed system.

Note: The installed OS and the Panorama PON versions must match the  versions of the server when it crashed, or the restoration will fail.
