Figure 52 Two-site failure scenarios that are correctly using a virtual manager
Configuring a cluster for disaster recovery
In addition to using a virtual manager, you must configure your cluster and volumes correctly for
disaster recovery. This section describes how to configure your system, including the virtual manager.
Best Practice
The following example describes configuring a management group with four storage systems in
one cluster. The cluster spans two geographic sites with two storage systems at each site. The
cluster contains a single volume with Network RAID-10 that spans both sites.
Configuration steps
The following configuration steps ensure that all the data is replicated at each site and the managers
are configured correctly to handle disaster recovery.
1. Name storage systems with site-identifying host names.
To ensure that you can easily identify which storage systems reside at each site, use host names
that identify the storage system location. See “Changing the storage system hostname” (page 22)
