SUMMARY

Windows 2000 supports two types of fault-tolerant volumes: mirrored volumes and RAID-5 volumes. This article describes how to set up fault-tolerant sets on dynamic disks in Windows 2000. This article includes basic procedures and a checklist for creating and modifying a fault-tolerant set. A fault-tolerant set includes a stripe set, a stripe set with parity, a volume set, and a disk mirror/duplex.

To Create a RAID 1 Set in Windows 2000

NOTE: All members of a RAID 1 volume set must be on a dynamic disk.
  1. Click Start, point to Programs, point to Administrative Tools, and then click Computer Management.
  2. Expand the Storage branch, and then click Disk Management.
  3. Right-click the partition that you want to mirror, and then click Add Mirror.
  4. Click the disk that will host the mirror, and then click Add Mirror.
  5. On the Partition menu, click Commit changes now to begin duplication.
  6. Reboot the computer after the duplication process is completed.

To Create a RAID 5 Set in Windows 2000

NOTE: Raid 5 is disk striping with parity. With this technique, you need a minimum of three hard disk to set up fault tolerance.
  1. Click Start, point to Programs, point to Administrative Tools, and then click Computer Management.
  2. Expand the Storage branch, and then click Disk Management.
  3. Right-click an area of unallocated space, and then click Create Volume.
  4. Click Next.
  5. Click a RAID 5 volume type, and then click Next.
  6. In the left pane, click the disks that you want to use (at least three in total), and then click Add.
  7. Select the size to use from each disk. The size must be the same for all disks, so the largest space that you can use is the smallest free space on any of the disks. After you select the size, click Next. Note that if you select 1,000 MB from each disk, the total size is only 2,000 MB because parity information uses a third of the space.
  8. Click a drive letter to use, and then click Next.
  9. Click the file system to use and the label. You might also want to choose whether to enable file and folder compression. Click Next.
  10. The program displays a summary screen. Click Finish.
