Configuring VMware virtual machines for disaster recovery using EMC SRDF replication
This section lists the prerequisites to enable data replication using EMC SRDF for the Veritas Resiliency Platform environment.
Add either a Discovery Host for discovering SRDF device groups, composite groups and storage groups, or add Unisphere to discover SRDF storage groups.
Ensure that the SRDF replicated LUNs are assigned to the respective VMware ESX Servers. Do not attach replicated peer SRDF LUNs (R1 and R2) to the same VMware ESX Server.
Note:
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 Symmetrix LUNs composing the datastore of the virtual machine's disk are grouped together into a SRDF device group storage group or composite group.
Note:
For EMC SRDF-based replication in Resiliency Platform, all virtual machines that consume storage from a Veritas Replication Set must belong to the same resiliency group.
Once you have performed the necessary configurations, proceed with Resiliency Platform specific tasks to add the asset infrastructure to Resiliency Platform for discovery by the Infrastructure Management Server (IMS).
Resiliency Platform configurations:
Using the Resiliency Platform console Infrastructure settings, you add the asset infrastructure for each data center (the production and recovery data centers). The following is a summary of the steps. More information is available.
See Adding the asset infrastructure.
Add the Symmetrix discovery host or Unisphere appropriate data centers. Provide the discovery host name and the SYMCLI location on this discovery host.
Default SymCLI location on Linux host
/opt/emc/SYMCLI/bin/
Default SymCLI location on Windows host
C:\Program Files\EMC\SYMCLI\bin
Any managed host can be designated as the array discovery host, including the virtual machine inside VMware ESX server that has EMC Symmetrix Gatekeeper device visibility and SYMCLI installed. The host on which composite groups are defined can also be used as an array discovery host.
This operation discovers the list of Symmetrix arrays (local and remote) accessible to the discovery host or Unisphere. To configure disaster recovery for the virtual machines, select one or more local arrays only.
Add the vCenter Servers to the appropriate data centers. The user needs to have vCenter administrator privileges.
Ensure that the virtualization server and ESX server are discovered successfully.
