Use the XenCenter Configure DR dialog box to identify storage repositories (SRs) where the metadata for a pool - configuration information about all the VMs and vApps in the pool - will be stored. This metadata will be updated whenever you make changes to VM or vApp configuration within the pool.

To configure DR on the primary pool:

1.  On your primary site, select the pool that you want to protect and on the Pool menu, point to Disaster Recovery and then click Configure.

2. Select up to 8 SRs where the pool metadata will be stored. A small amount of space will be required on this storage for a new LUN which will contain the pool recovery information.

   Note: XenServer DR can only be used with LVM over HBA or LVM over iSCSI storage types.

3. Click OK.

   Important: Your XenServer DR environment will not be fully configured until the SRs containing the pool metadata and the virtual disks used by the VMs in the pool are replicated from your production environment to a backup environment. Storage replication, for example using mirroring, is best handled by your storage solution, and will vary from device to device; it cannot be configured from within XenCenter.
