C.5 Synchronous Long Distance Remote Copy Disaster Recovery
Example

For Synchronous Long Distance Remote Copy set ups, there are three common failover

scenarios where the primary server fails and one of the backup servers assumes the role of the

primary server until the original primary server is brought back online. These scenarios are as

follows:

The primary server goes down and the synchronous backup server assumes the role of the

primary server. See

Synchronous Backup Server Assumes Role of Primary Server

on

page C.43.

The primary server goes down and the asynchronous periodic backup server assumes the

role of the primary server after data has been transferred from the synchronous backup

On InServ2:
