HP 3PAR StoreServ Cluster Extension Software Administrator Guide (5697-2442, July 2013)

The following command adds a dependency on the HP 3PAR StoreServ Cluster Extension
clx_fileshare resource to the physical disk resource Disk_32b_00b:
cluster resource Disk_32b_00b /adddependency:clx_fileshare
Adding dependencies using the PowerShell
1. To add dependency on a HP 3PAR StoreServ Cluster Extension resource using the PowerShell,
use the following command:
Add-ClusterResourceDependency -Resource <Name_of_the_disk_resource>
– Provider <CLX3PAR_Resource_Name>
2. The following command adds a dependency on the HP 3PAR StoreServ Cluster Extension
clx_fileshare resource to the physical disk resource Disk_32b_00b:
Add-ClusterResourceDependency -Resource “Disk_32b_00b”-Provider
clx_fileshare
Configuration of HP 3PAR StoreServ 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. Due to this
restriction, you 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 60).
• 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 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)” (page 31) 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 StoreServ Storages 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 40) 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.
