Chapter 2. Installing and cabling a ServeRAID controller
This chapter provides installation and cabling instructions for ServeRAID-4
controllers.
If you are using a ServeRAID controller on an IBM server system board, you will
not need the information in this section. Go to “Chapter 3. Understanding RAID
technology” on page 15.
Using a ServeRAID controller in a server with Active
™
PCI features
Some IBM servers support Active PCI (also called Hot-plug PCI) features. You can
use these features to install or remove PCI controllers without turning off the server.
The ServeRAID-4 controller supports Active PCI functions on Windows NT 4.0,
Windows 2000, and NetWare. The following table summarizes which operating
systems support these features:
Feature Windows NT
4.0 Windows 2000 NetWare 4.x NetWare 5.x
Hot add Yes Yes No Yes
Hot remove No Yes Yes Yes
Hot replace Yes No No No
Attention: Do not attempt a hot-replace operation on Windows 2000 or NetWare
by hot-removing a failed controller and then, hot-adding a new controller. Loss of
data can occur. If a controller fails on these operating systems, you must shut down
the server to replace the controller.
You can use the hot-add feature to expand capacity in a server by adding a
controller. Use the hot-remove feature to remove a controller from a running server.
If a controller fails, use the hot-replace feature to replace a controller with an
identical controller.
Using Windows NT 4.0 with Active PCI features
To use Active PCI with Windows NT 4.0 and a ServeRAID-4 controller, you must
install the IBM Hot Plug for Windows NT 4.0 Package, version 4.1 or later. This
package is available from the IBM Support Web site; select downloadable files for
the IBM server you are using. See “Downloadable files from the World Wide Web”
on page 131 for additional information.
Note: Be sure to read the instructions and restrictions for this software program.
Also, when installing the ServeRAID Manager program, you must choose to install
the IBM ServeRAID Hot Replace Wizard.
To perform a hot-replace operation, start the IBM ServeRAID Hot Replace Wizard.
You can start this program from within either the IBM Hot Plug for Windows NT 4.0
program or the ServeRAID Manager program. You can use the ServeRAID
Manager program to start the wizard either on the server with the failed controller,
or across the network from a remote installation of the ServeRAID Manager.
