If the production server fails, you can temporarily run the production systems on the recovery server through the failover operation.
This transition requires that the configuration of the failover operation is specified in a failover context. You create a failover context to configure a context that is specific to your failover operations.
The failover context provides Assure MIMIX for AIX with the configuration information used to operate as if the original recovery was actually a production server, and the original production server, when it comes back on-line, was actually the recovery server.
You set up the failover context in association with the primary context for the production server. This failover context enables you to perform the system failover and failback operations, including managing all the required transitions from the Production environment to the recovery server.
To accomplish this, Assure MIMIX for AIX uses the block-ordered replica maintained on the recovery as the failover disk, on which it brings up the production server.
