failover operation quicker. CSV also enables quicker live migration that allows you to move a
running VM from one node to another node with zero downtime.
As disk ownership does not change when a VM moves from one to another node, the process
becomes quicker and safer. This allows the client nodes to stay connected while the VM is moved
to another node in the cluster. The CSV disk resource that is owned by a cluster node is known as
a coordinator node. The VMs hosted on the CSV disk can be owned by either the coordinator
node or any other node in the cluster. When a disk is in the available storage group, it can be
converted to a CSV. When a CSV disk is created in the Failover Cluster, a role is internally created
by the failover cluster which is hidden, and is visible through the cluster.exe command output
or through the PowerShell Cmdlet output, and not in the Failover Cluster GUI. Only CSV disk is
shown on the Failover Cluster GUI. The name of the CSV role is in the form of a GUID. For every
highly available VM that is created on the CSV, a VM role is created in the Failover Cluster that
is independent of the CSV role. Figure 3 (page 10) shows two virtual machines created on a single
CSV Disk. For each virtual machine, a role is created.
In a multi-site storage array replicated environment, CSV disks are replicated to the remote
datacenter using the array based remote replication feature. VMs residing in the CSV disk can run
on any cluster nodes (physical servers). In case of a disaster in the primary datacenter, CSV disks
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.

HP XP 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 XP resource for the CSV disk. For information about
