Configuration of EVA CLX for CSV disk on Windows Server 2012
Configuration of CLX resource for the CSV disk is a two-step process. This is almost similar to the
configuration of CLX for non-CSV disk.
• Creation of CLX resource in the CSV Role
The CSV disk resides in its own role in the Failover Cluster. The CSV disk is visible in the
Failover Cluster Manager GUI, but the role in which the CSV disk resides is not visible. Because
of this restriction, you will not be able to create a CLX resource in the CSV role to manage
the CSV disk using Failover Cluster Manager GUI.
To overcome this limitation, CLX provides PowerShell Cmdlets to create CLX resource in the
CSV role and set the dependency of the CSV disk on the CLX resource. For more information,
see “Cluster Extension Cmdlets for CSV and Virtual Machine Management” (page 58).
• Setting the private properties for the CLX resource
After creating the CLX resource in the CSV role and setting the dependency of CSV disk on
the CLX resource, the private properties of the CLX resource must be configured. Because the
CSV role is not visible in the Failover Cluster Manager GUI, the CLX resource created in the
CSV role is also not visible in the Failover Cluster Manager GUI. For information about setting
the private properties of CLX resource created in the CSV role, see “ Using Failover Cluster
Management to set resource properties of a CLX resource on which a CSV disk is dependant
(Windows Server 2012)” (page 28) .
After completing these two steps, the CLX is ready to manage the CSV disks.
Disaster-tolerant configuration example using a file share
The following example assumes that your environment includes:
• Four nodes (host1_DCA, host2_DCA, host3_DCB and host4_DCB)
• Two EVA storage systems with WWNs 50001fe15002B5A0 and 50001fe15002B570
• A DR group configured as \Data Replication\DRG_LUN25
• Two management servers SMAM019FK351K and SMAM019FK001A
• An MNS arbitrator node in a third site or separate protected area
• A pre-executable clxpre.exe to be invoked by the software
The default failover behavior is used for the cluster group.
