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, see Chapter 4, “Configuring ServeRAID controllers” on page 35.
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. The two servers must have
the same drive letters on each shared drive. If you do not assign permanent drive letters,
Windows 2000 might assign different drive letters on each server. Assigning a permanent
drive letter ensures that Windows 2000 assigns the same drive letter to the partition on both
servers.
Complete the following steps to create additional ServeRAID disk resources:
1. On Server A, do the following:
a. Right-click My Computer ; then, click Manage . The Computer Management
window opens.
b. Double-click Storage .
c. Click Disk Management . The Write Signature and Upgrade Disk Wizard
opens.
d. Right-click Disk Management → Rescan Disks .
e. On each of the new disks, complete the following tasks:
1) Right-click 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) Right-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 the 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.
2. On Server B, do the following:
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.
