HP 3PAR Cluster Extension Software Administrator Guide (5697-1429, March 2012)

Adding dependencies using the CLI
The cluster commands in this section can be used with Windows Server 2003, Windows Server
2008/2008 R2, Server Core, or Hyper-V Server.
To add a dependency on a HP 3PAR Cluster Extension resource using the CLI, use the following
command:
cluster resource physical_disk_resource
/adddependency:Cluster_Extension_3PAR_resource
The following command adds a dependency on the HP 3PAR Cluster Extension clx_fileshare
resource to the physical disk resource Disk_32b_00b:
cluster resource Disk_32b_00b /adddependency:clx_fileshare
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 MNS 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.
