Creating Fault-Tolerant Volumes Using Disk Management

Windows Server 2008 R2 supports fault-tolerant disk arrays configured and managed on a RAID disk controller or configured within the operating system using dynamic disks. To create arrays using a RAID controller, refer to the manufacturer’s documentation and use the appropriate disk utilities. To create a fault-tolerant volume within the Windows Server 2008 R2 operating system using the Disk Management snap-in, perform the following steps:

1. Log on to the Windows Server 2008 R2 system with an account with administrator privileges.

2. Click Start, click All Programs, click Administrative Tools, and select Server Manager.

3. In the tree pane, double-click the Storage node, and select Disk Management.

4. In the tasks pane, verify that each of the disks that will be part of the fault-tolerant volume is listed as online.

5. After all of the necessary disks are online and initialized, they should be converted to dynamic disk. Once all of the disks are ready, right-click any of the disks and select either New Mirrored Volume or New RAID-5 Volume to create a fault-tolerant volume. For this example, we will be creating a RAID-5 volume, but the steps would be the same for a spanned or striped volume.

6. After selecting New RAID-5 Volume, a New RAID-5 Volume window opens; click Next on the Welcome page.

7. The disk that was right-clicked will already be selected. For each remaining disk that will be part of the RAID-5 volume, select the disk in the Available section, and click the Add button to move it to the Selected section. For this example, we will create a RAID-5 volume using disks two through seven.

8. After all the necessary disks are listed in the Selected section, unless only a section of the disk will be used in the volume, the entire disk space will be used. Click Next to continue.

9. On the Assign Drive Letter or Path page, select the drive letter to assign or browse to a folder location to mount the volume into an empty folder, and then click Next.

10. On the Format Volume page, accept the defaults to format the volume as NTFS, accept the default allocation size, and type in the volume label as required to easily identify the drive in Disk Manager, diskpart.exe, and Explorer. Uncheck the Perform a Quick Format check box, and click Next.

11. On the Completing the New RAID-5 Volume Wizard page, review the settings and click Finish to create and format the volume.

12. If any of the disks were not previously converted to dynamic disks before the start of the volume creation, a window opens to confirm that all disks will be converted; click the Yes button to accept the conversion of the necessary disks.

Because a quick format was not selected, the time it takes to format the volume might be extensive, so please plan accordingly.

When you’re formatting RAID-5 volumes, perform a complete format to avoid loss of disk performance later when data is first copied to the volume.
