Configure the Agent to Run on a Cluster Configure the Agent to Run on a Cluster For the agent to properly perform document level backups on a cluster, the cluster resource type CA ARCserve Backup Exchange Agent Notifier must be registered and the resource instance type CA ARCserve Backup Exchange Agent Notifier must be created. The binaries for the cluster resource type are CAExCluRes.dll and CAExCluResEX.dll. The installation procedure registers the cluster resource type and creates the cluster resources instance for you automatically when you install the agent on local nodes. After the cluster resources are registered, you must specify a common location for the check point file. This location should be accessible from all possible nodes on which a virtual server can potentially run. This allows job continuation and incremental and differential jobs to properly execute even if they fail over to a different node. To set this destination, use one of the following registry keys: Exchange Server 2000 and Exchange Server 2003 Systems HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCserve Backup\ExchangeDocumentAgent\Parameters Value Name: _ChkPath Value Type: REG_SZ Value Data: Exchange Server 2007 Systems HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\CA ARCserve Backup\ExchangeDocumentAgent\Parameters Value Name: _ChkPath Value Type: REG_SZ Value Data: Example: Traditional Single Copy Cluster (SCC) If virtual server EXVS1 is using drive g: as a disk resource to store data and virtual server EXVS2 is using drive h: as a disk resource to store data, add the following registry key on all nodes that are possible owners of these virtual servers. Value Name: Value Type: Value Data: EXVS1_ChkPath REG_SZ g:\CA\Temp Value Name: Value Type: Value Data: EXVS2_ChkPath REG_SZ h:\CA\Temp Chapter 2: Installing the Agent 29
