Creating additional ServeRAID disk resources on a Windows 2000
ServeRAID cluster
You can use a ServeRAID logical disk that has not already been designated as a
cluster resource, or you can create a new array and logical disk on Server A, using
the ServeRAID Manager program. For more information about creating new arrays
and logical drives, refer to "Chapter 4. Configuring ServeRAID controllers" on
page 27.
Note: Be sure to assign a unique shared merge group number to the new shared

logical drive.
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.

1) Using the right-mouse button, click on a new disk; then, click Write
Signature. The Write Signature Wizard opens. Follow and complete the
wizard.
2) 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:
a) With the right-mouse button, click the Disk icon at the bottom of the
Disk Management window.
b) Click Revert to Basic Disk.
3) Create one partition on the disk (the full size of disk), assign a drive
letter, and format the partition to NTFS.
Note: To help recognize the drive on the cluster partner server, assign a
descriptive volume label that includes the drive letter.
a. Using the ServeRAID Manager program, scan for new or removed ready
drives on all ServeRAID controllers.
b. To move the newly defined logical drive to Server B, start the
IPSHAHTO.EXE program by typing:
%systemroot%\cluster\ipshahto.exe
where %systemroot% is expanded by the operating system to the root
directory of the operating system on Server B.
