must be brought online in the secondary datacenter. Ensure that you check the CLX disaster recovery
rules, and then carry out the storage failover before the cluster brings the CSV disk online. In a
disaster scenario, CLX swaps the replication direction and performs the storage failover
automatically, adding failover capabilities for the CSV disks in the clustering environment.

EVA Cluster Extension supports CSV as well as non-CSV disks on Windows Server 2012. The
configuration of CSV disk for CLX is similar to the configuration of normal disk for CLX support.
Because the CSV role is hidden and not seen in Failover Cluster GUI, CLX has provided PowerShell
Cmdlets to configure Cluster Extension EVA resource for the CSV disk. For information about
configuring CSV disk for CLX, see “Cluster Extension Cmdlets for CSV and Virtual Machine
Management” (page 58).
