Ways to determine whether a disaster occurred

You should declare a disaster only after using predefined procedures to verify that service cannot be restored.

It is critical that you follow a predefined procedure to confirm that a disaster occurred. The procedure should include determining the status of the disaster site by:

  • Using external interfaces to the storage system, such as the following:
    • ping command to verify network connectivity
    • Remote shell
    • FilerView administration tool
  • Using network management tools to verify connectivity to the disaster site
  • Physically inspecting the disaster site, if possible

You should declare a disaster only after verifying that service cannot be restored.
