Recovery scenarios for planned and unplanned outages using Metro/Global Mirror

Edit online

Information is provided to help use Metro/Global Mirror functions during planned and unplanned outages.

In a Metro/Global Mirror environment that uses failover and failback operations, you can switch applications to an alternate site during planned and unplanned outages. Planned outages are events such as maintenance updates. Unplanned outages are events such as disasters.

Several scenarios, including the following, are described:
  • Setting up a Metro/Global Mirror environment
  • Failover and restore operations to the intermediate (B) site
  • Failover and restore operations to the remote (C) site
Note: The steps in these scenarios are examples. Other configurations might be possible but might not be supported.
