98 Implementing the IBM General Parallel File System (GPFS) in a Cross-Platform Environment
After the cluster is fully configured, a simple (write/read) test application is run on the GPFS
file system from both Windows nodes concurrently to show file system availability and data
integrity.
In the test, concurrently simulated errors are injected on either of the Windows servers to
verify the file system remains available from the surviving Windows node.

3.5.4 Installing Windows Server 2008 R2
Table 3-2 shows the Windows cluster nodes, names and IP addresses.
Table 3-2 Windows server configuration showing IP addresses
The basic installation steps for a Windows Server 2008 R2 on Node1 are as follows:
Set up the Active Directory and use itso.com as the domain name
The following procedure disables password complexity to an account when the Windows
domain controller is running on Windows Server 2008 R2:
1. Open the Group Policy Management Editor (available under Administrative Tools).
2. In the console tree, select Forest name Domains Domain name Group Policy

Change the default firewall rule settings
The following procedure changes the default firewall rule setting to allow the Windows nodes
to communicate in the GPFS cluster in a Windows domain controller running on Windows
Server 2008 R2:
1. Open the Group Policy Management Editor (available under Administrative Tools).
2. In the console tree, select Forest name Domains Domain name Group Policy
Objects.
3. Right-click Default Domain Policy and select Edit.
