- The network path that is chosen for data replication between each pair of servers must also already be configured as a LifeKeeper communication path between those servers. To change the network path, see Changing the Data Replication Path.
- Avoid a configuration to add virtual IP address with IP Recovery Kit to the network interface that DataKeeper users for data replication. Since the communication line is temporarily disconnected while IP Recovery Kit uses the network interface, data replication may stop at unexpected timing and unnecessary resynchronization may occur.
- This release of SIOS DataKeeper does not support Automatic Switchback for DataKeeper resources. Additionally, the Automatic Switchback restriction is applicable for any other LifeKeeper resource sitting on top of a DataKeeper resource.
- If using Fusion-io, see the Network section of Clustering with Fusion-io for further network configuration information.
