HP XP Cluster Extension Software Administrator Guide

Figure 5 XP Cluster Extension resource tree for CLX_SHARE
XP Cluster Extension is configured as a single resource to enable read/write access to the physical
disk resource used for the CLX_SHARE cluster group. The physical disk resource depends on the
XP Cluster Extension resource and can be brought online only when the XP Cluster Extension
resource is already online. Independent of this resource tree, the network card will be configured
with the CLX_SHARE service or application's (resource group's) IP address and network name.
If all those resources have been brought online, the file share can be started.
To configure the XP Cluster Extension resource according to the configuration in “ XP Cluster
Extension resource tree for CLX_SHARE” (page 33):
1. Log in to the host3_DCB system with the Administrator account.
2. Create the file share service or application with all previously mentioned resources and its
dependencies, except the XP Cluster Extension resource on host3_DCB.
3. Create a new resource of type Cluster Extension XP and add systems host2_DCA, host3_DCB,
and host4_DCB to its possible owners.
4. Change the restart behavior of the XP Cluster Extension resource so that the resource can be
restarted and so that the restart affects the group. Set the number of restarts to 0.
5. Edit the resource properties, including the following information:
• RAID Manager instances
• RAID Manager device/copy group details
• Server data center assignments
6. Click the Pre/Post Exec button and add clxpre.exe with its full path. (The clxpre.exe
program is an example. It is not included in the XP Cluster Extension product.)
7. Add a dependency on the XP Cluster Extension resource CLX_FILESHARE to the physical disk
resource Disk_32b_00b.
8. Check the cluster service, group, and resource settings with the following commands:
C:\>cluster group CLX_SHARE /prop
C:\>cluster resource CLX_FILESHARE /prop
