Before configuring DR services, check whether the VMware VM environment and storage environment at the production and DR ends meet requirements. If any environment does not meet requirements, modify its configuration.
The following check items must be checked and configured in the VM environments at the production and DR ends.
For details about the VMware versions supported by eReplication, see the Application Support Matrix sheet in the OceanStor BCManager 8.5.1 eReplication Compatibility List. Check whether the vSphere vCenter version is applicable before configuring DR. You are advised to use vSphere vCenter of the same version at the production and DR sites. Otherwise, the version of the installed VMware Tools or Open VM Tools will be incompatible. As a result, unexpected errors may occur. The vSphere vCenter version must be the same as the ESX version. Otherwise, unexpected errors may occur.
You will be prompted by an alarm about installing a certificate upon the login. Install a certificate as instructed or ignore the alarm.
The vSphere vCenter administrator account is required for login. This account is also required for subsequent vSphere vCenter discovery operations. Obtain the account in advance.

Before performing DR protection for or recovering VMs, ensure that VMware Tools or Open VM Tools has been installed on the VMware VMs. The VMware Tools version or Open VM Tools needs to match the vSphere vCenter version. VMware VMTools or Open VM Tools of a later or earlier version may cause unexpected errors during protection and restoration. For details about how to obtain and install VMware Tools or Open VM Tools, see the related VMware documentation.
Choose Inventory > Hosts and Clusters. In the navigation tree, click a VM that requires DR protection. In the function pane, click the Summary tab and view information about VMware Tools or Open VM Tools in the General area. If VMware Tools or Open VM Tools is not installed on the VM, install it. If the VMware Tools or Open VM Tools version is not correct, install a correct version.
