SAP HANA

Before configuring DR services, check the SAP HANA database environment at the production end and the storage environment. If any environment does not meet requirements, modify its configurations.

Public Check Items

Check and configure the following items in the SAP HANA database environment at the production ends.

When the host where the database resides run SUSE 11 or 12, or Red Hat 7, the mount points of the file system used by the database cannot be nested. For example, mount points /testdb/ and /testdb/database1/ are nested.
Before configuring an SAP HANA database, obtain the name and account (including username and password) of the database instance.
The instance name is the one you created, the username is the username of the system corresponding to the instance and usually is the same as the instance name.
Ensure that the password meets the complex requirements. Otherwise, databases may fail to be authenticated when you create a protected group.
The password can only contain letters, digits, and the following special characters: _#%^+-.,~@$

Check Items at the Production End

Check the database configuration at the production end.

eReplication of the latest version can protect SAP HANA databases in SUSE 11 and 12, and Red Hat 7 when the SAP HANA databases meet the following requirements:

Installation directories of SAP HANA instances must reside on local disks or independent storage devices and cannot reside on the same devices as databases for which DR is intended.
Data and log files of the SAP HANA databases for which DR and protection are intended must be stored on LUNs provided by Huawei storage devices.
If the scheduling period of the protection policy is set to Second, data files and log files of SAP HANA databases must be stored on different LUNs provided by Huawei storage devices.

Check Items at the Storage End

Check whether information about initiators of production hosts (cluster) and test hosts (cluster) is displayed on the array.
Check that the production LUN has been mapped to the production host (cluster). For a cluster consisting of hosts, ensure that the hosts included in the host group to which the primary and secondary LUNs are mapped are all the hosts only in the cluster.
