   • You can choose not to install administration tools to shorten the installation time. If you choose to install the tools, the tools are only installed on the current cluster node.
9. On the Instance Name page, select a default or named instance for your installation. If a default or named instance is already installed and you select the existing instance for your installation, the Setup program upgrades the existing instance and lets you install additional components.
   
   To install a new default instance, no default instance should exist on the computer.
   
   To install a new named instance, click Named Instance, and then type a unique instance name.
   
   For more information about instance naming rules, visit the following MSDN Web site:
   http://msdn2.microsoft.com/en-us/library/ms143531.aspx (http://msdn2.microsoft.com/en-us/library/ms143531.aspx)
10. On the Virtual SQL Server Name page, type a unique name for the clustered Analysis Services. This name is used to identify the failover cluster on the network. The virtual SQL Server name must be unique on the network and must have a name that differs from the host cluster and cluster nodes. Click Next.
11. On the Virtual SQL Server Configuration page, enter one IP address for each network that is configured for client access. For example, enter one IP address for each network on which the virtual SQL Server is available to clients on a public (or mixed) network. Only one IP address is allowed on each subnet.
    
    To avoid IP address conflicts, make sure that the IP address that is assigned to a subnet is not shared by any other applications.

How to verify whether the installation is successful

To verify whether Analysis Services has been successfully installed on each cluster node, verify that all the following conditions are true:

• For each cluster node, open the Cluster Administrator tool, and then click the cluster group that you selected in step 12 in the "How to install Analysis Services on a failover cluster" section. You must find Analysis Services listed as a resource of the cluster group.
• For each cluster node, you find SQL Server Analysis Services listed in the services list when you open the Services tool.
  
  Note We do not recommend that you perform any operation on this service at any cluster node. You can manage the clustered Analysis Services by using the Cluster Administrator.
• For each cluster node, the Analysis Services program files were copied to the following folder:
  SystemDrive:\Program Files\Microsoft SQL Server
• The Analysis Services data files must be copied to a folder that is created on the shared drive. By default, if you did not specify a custom path for the data files, the files are copied to the following folder:
  SharedDrive:\Program Files\Microsoft SQL Server
• SQL Server Management Studio and SQL Server Business Intelligence Development Studio must be installed on the cluster node on which you run the Setup program. SQL Server Management Studio and SQL Server Business Intelligence Development Studio must not be available in the other nodes.
• You can connect to the clustered Analysis Services by using the virtual server name that you specified step 10 in the "How to install Analysis Services on a failover cluster" section.
  
  Note Even if you install the instance of SSAS as a named instance, you must specify the named instance as the virtual server name. You cannot use VirtualServerName/InstanceName to connect to the instance.

How to remove Analysis Services from a failover cluster

To remove the clustered Analysis Services, follow these steps:

1. Insert the SQL Server 2005 installation media in the disk drive.
2. Run the following command at a command prompt:

   Start /wait <DiskDrive>\setup.exe /qb REMOVE=Analysis_Server INSTANCENAME=<InstanceName>

Note <InstanceName> represents the name of the instance of SQL Server 2005 Analysis Services that you want to remove.

You cannot use Add or Remove Programs to remove an instance of SQL Server 2005 Analysis Services on a failover cluster. However, you can manually remove the Microsoft SQL Server Native Client by using Add or Remove Programs in Control Panel.

Known issues

• When you install Analysis Services in a cluster group, you must make sure that the status of the group is Online.
• If you run the Setup program from a terminal session, you must make sure that other users are logged off from cluster nodes.
• If the installation source files are on a network share location, you must make sure that all the cluster nodes can access the share location successfully.
• You must be either a member of the Domain Admin group or the owner of the domain group of which you want the cluster service account to be a member. Otherwise, you may receive the following error message:
  You do not have privileges to add account to the domain groups specified for this failover cluster. Ask your domain administrator for privileges to add new accounts to the domain groups, or log on using an account that does have permission.
