Manual Switchover to a Target ServerManual Switchover to a Target ServerIn the event the administrator wants to make Server B become the active (source) server, the followingactions will occur:1. Administrator initiates a switchover to Server B via the Switchover Mirror option in the DataKeeperUI.2. Server A flushes its data to the source volume.3. Mirror 1 is automatically deleted and recreated from Server B to Server A.4. The mirror between Server A and Server C is also automatically deleted. (Note: There will be a fewseconds delay noticed in the DataKeeper GUI; this delay can take some time based on networkbandwidth and server performance.)5. A new mirror is established between Server B and Server C. The intent log from Server A is copied toServer B. Only a partial resync of the data between Server B and Server C is required to bring them insync. (A partial resync is the resynchronization of only the necessary data to establish the new endpoints and is usually much quicker than a full resync.)RESULT• Mirror 1: Server B → A (partial resync)• Mirror 2: Server B → C (copy intent log from Server A, partial resync)DataKeeper for Windows Technical DocumentationPage 105
