Configuration of HP 3PAR CLX for CSV disk on Windows Server 2012

Configuration of CLX resource for the CSV disk is a two steps process. This is almost similar to the configuration of CLX for non CSV disk.

•Creation of CLX resource in the CSV Role

CSV disk resides in its own role in the Failover Cluster. CSV disk is visible in the Failover Cluster Manager GUI but the role in which the CSV disk resides is not visible to the user. Due to this restriction, user will not be able to create CLX resource in the CSV role to manage the CSV disk using Failover Cluster Manager GUI.

To overcome this limitation, CLX has provided PowerShell Cmdlets to create CLX resource in the CSV role and set the dependency of CSV disk on 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. Since the CSV role is not visible in the Failover Cluster Manager GUI, CLX resource created in the CSV role is also not visible to the user in the Failover Cluster Manager GUI. See “ Using Failover Cluster Management to set resource properties of a CLX resource on which a CSV disk is dependant (Windows Server 2012 and Windows Server 2012 Server Core)” (page 28) for information on how to set the private properties of CLX resource created in the CSV role.

Once the above steps are completed, CLX is ready to manage 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 HP 3PAR storage systems with Serial number 1301811 and 1301812

•A Remote Copy volume group configured as VG_CLX01

•An Node Majority arbitrator node in a third site or separate protected area

•A pre-executable clxpre.exe to be invoked by the software

Figure 5 (page 38) illustrates failover options and shows a second cluster group CLX_IIS. The resource CLX_FILESHARE is part of the service group CLX_SHARE and must be brought online before the physical disk resources Disk_3PAR_LUN25.
