cluster resource Disk_32b_00b /adddependency:clx_fileshare
Powershell Cmdlets can also be used instead of cluster.exe to add dependencies. For more
information, see Microsoft documentation.
Adding dependencies using the PowerShell
1. To add dependency on an HP XP Cluster Extension resource using the PowerShell, use the
following command:
Add-ClusterResourceDependency -Resource <Name_of_the_disk_resource>
– Provider <CLXXP_Resource_Name>
2. The following command adds a dependency on the HP XP Cluster Extension clx_fileshare
resource to the physical disk resource Disk_32b_00b:
Add-ClusterResourceDependency -Resource “Disk_32b_00b”-Provider
clx_fileshare
Configuration of XP CLX for CSV disk on Windows Server 2012/2012
R2
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 52).
• 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 2012/2012 R2)” (page 26) .
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 describes a configuration in which:
• Your environment consists of four systems (host1_DCA, host2_DCA, host3_DCB and
host4_DCB).
• Your environment includes two disk arrays with serial numbers 35014 and 35013.
• You have configured clxfileshare as a device/copy group in the RAID Manager
c:\windows\horcm101.conf file and in the c:\windows\horcm102.conf file.
• A pre-executable clxpre.exe will be invoked by HP XP Cluster Extension.
• You use the default failover behavior for the cluster group.
• The resource CLX_FILESHARE is part of the service group CLX_SHARE and must be brought
online before the physical disk resource Disk_32b_00b.
