Configuring disaster recovery for a resiliency group of virtual machines


Configuring disaster recovery for a resiliency group of virtual machines
Prev	Preparing for disaster recovery operations	Next

When configuring disaster recovery (DR), Veritas Resiliency Platform searches the complete storage stack from the virtual machines to the replicated volumes. It also detects the complete network settings of each member of the resiliency group and applies the Subnet, VSwitch, PortGroup mappings details to the current network settings that needs to be applied after Migration in the disaster recovery data center. The Resiliency Platform stores and uses this configuration at the time of disaster recovery operations, such as, Migrate, Takeover, or Rehearse.

Note:

If there are any changes to the storage stack, or network settings in any of the resiliency group members, please make sure to re-run the DR Configuration wizards so that the latest storage and network configuration snapshot are recorded.

For VMware virtual machines consider the following:

After performing the configure DR operation, the Resiliency Platform creates a directory in the working location of the virtual machine to save the virtual machine related files for the recovery data center. Resiliency Platform uses these files during the DR operations such as Migrate, Takeover, Rehearsal, hence these files and the directory should not be deleted or modified. This directory lets you have separate configurations across the two data centers for the same virtual machines.
If a virtual machine has more than one ethernet adapters then all of them should have either static IP configuration or DHCP IP configuration. Mix of static and DHCP IP configuration is not supported on the same virtual machine.
All the virtual disks must be connected to the virtual SCSI controllers. Other controller types are not supported. Also all the virtual disks must belong to a single datastore.

Use this procedure to configure disaster recovery (DR) for a selected resiliency group. A successful DR configuration enables takeover, migrate, and rehearse operations.

To configure disaster recovery for a resiliency group

Navigate

Assets (navigation pane)

Resiliency Groups
Double-click the desired resiliency group.
In the resiliency group details page, click Configure DR.
In the Select DR Data center page, select the target data center, and click Next.
See Configuring disaster recovery - DR data center selection.
The VM Selection page displays the matching virtual machines available at the DR data center. Click Next.
In the Summary page, review the information on virtual machine pairing and network customization.
See Configuring disaster recovery - Summary.
Click Submit to complete the disaster recovery operation for the resiliency group.
Post configuration, verify whether the DR Status column on the resiliency group details page displays the status of the resiliency group as CONFIGURED.
After you have successfully configured the resiliency group for DR operations, Resiliency Platform invokes a workflow which initializes the virtual machines for DR operations.
Ensure that this operation is successfully completed by checking in Current or Completed activities page. The operation will be listed as " Process for initializing resiliency group for DR operations."
