6. Microsoft Cluster Service using Windows 2000 requires you to set shared
logical drives to Basic Disk. To do this, click Cancel in the Upgrade Disks
panel of the window.
7. Format all shared logical drives to NTFS (NT File System), assign volume
labels, and specify drive letters for each.
Important
Before creating the ServeRAID logical cluster resource, you must assign a permanent
(sticky) drive letter to the shared logical drive on both servers.
When configuring a cluster, you must assign a permanent drive letter because the two
servers must have the same drive letters on each shared logical drive. If you do not assign
permanent drive letters, Windows 2000 might assign different drive letters on each server.
You must assign a permanent drive letter to ensure Windows 2000 assigns the same drive
letter to the partition on both servers.
Notes:
a. It is helpful if part of the volume label that you assign contains the drive
letter that you assigned to the drive, such as DRIVE E.
b. If you want to use the disk in a cluster, create only one partition on the
disk. Make the partition the full size of disk and format the partition to
NTFS.
c. Make sure that all shared logical drives are the type Basic Disk. If they are
marked Dynamic Disk, change them to Basic Disk by doing the following:
1) With the right-mouse button, click the Disk icon at the bottom of the
Disk Management window (see Figure 28 on page 116).
2) Click Revert to Basic Disk.
