Configuring VMware virtual machines for disaster recovery using HPE 3PAR Remote Copy replication
This section lists the prerequisites and limitations to enable data replication using HPE 3PAR Remote Copy replication.
Ensure that the Infrastructure Management Server (IMS) is able to communicate with HPE 3PAR array using SSH.
Confirm that HPE 3PAR array user has edit or super role to perform HPE 3PAR Remote Copy operations.
Ensure that the HPE Remote Copy groups are set up for replication between the primary and the remote arrays. Ensure that the group names are unique across all data centers. Group name on the recover data center is auto generated by HPE. Do not modify the name.
Ensure that the HPE 3PAR Remote Copy replicated LUNs are assigned to the respective VMware ESX Servers.
If any changes are made to storage or storage-adapters available to the ESX/ESXi host or cluster, you must perform storage rescan, storage adapter rescan or both depending on the changes made.
Ensure that the LUNs composing the datastore of the virtual machine disks, or the LUNs that are presented as raw devices to virtual machines are grouped into one or more Remote Copy groups.
For HPE 3PAR Remote Copy based replication, all virtual machines that consume storage from a 3PAR Remote Copy group must belong to the same resiliency group. A 3PAR Remote Copy group is a collection of volume groups that helps in maintaining write consistency during replication.
Once you have performed the necessary configurations, proceed with Resiliency Platform specific tasks to add the asset infrastructure to the Infrastructure Management Server (IMS). The following is a summary of the steps.
See Adding the asset infrastructure.
Resiliency Platform configurations:
Add the 3PAR enclosure to the IMS using the + HP Enclosure option at each data center.
Add the vCenter Servers to their respective IMS in each data center using the option. The user needs to have vCenter administrator privileges. Ensure that the virtualization server and ESX server are discovered successfully.
Limitations:
HPE 3PAR Remote Copy synchronous replication is not supported.
3PAR storage connectivity via iSCSI is not supported.
