Replicating the ASCS and ERS

1. Configure target servers by following the instructions provided in Configuring the Target ECS. The target servers must have same disks as the source servers have. The shared disk of the target ASCS is the same as that of the source ASCS, and that of the target ERS is the same as that of the source ERS.

2. Start server replication. For details, see Starting Replication.

3. Launch target servers. For details, see Launching the Target ECS.

Note: Before launching target servers, ensure that SAP in the source system is not set to automatically start upon power-on.

4. Check the target server configuration.

1. On the HUAWEI CLOUD management console, mount the ERS shared disk to ASCS and the ASCS shared disk to ERS.
2. Create an SBD shared disk and mount it to ASCS and ERS based on the delivery LLD.
3. Run the dh -h command to check whether the file system of the target system (except the NFS file system) is the same as that of the source system.
4. Query the /etc/fstab configuration file to check whether the directories and items (except the NFS file system) mounted during startup are the same as those in the source system.
