Chapter 2. Installing and cabling a ServeRAID controller
This chapter provides installation and cabling instructions for the IBM ServeRAID
controllers.
You can install a maximum of 12 ServeRAID controllers in a server.
Using a ServeRAID controller in a server with Active PCI features
Note: The ServeRAID-5i controller does not support Active
™
PCI features.
Some IBM servers support Active PCI (also called hot-plug PCI) features. The
ServeRAID-3 and ServeRAID-4 controllers support Active PCI features on Windows
NT 4.0, Windows 2000, and Novell NetWare. The following table summarizes which
operating systems support specific Active PCI functions:
Feature Windows NT
4.0 Windows 2000 NetWare 5.x NetWare 6.0
Hot add Yes Yes Yes Yes
Hot remove No Yes Yes Yes
Hot replace Yes No No No
You can use the Active PCI features to install, remove, or replace PCI controllers
without turning off the server.
v
Use the hot-add feature to add a controller to a running server, thus expanding
its capacity.
v Use the hot-remove feature to remove a controller from a running server.
v
Use the hot-replace feature to replace a controller with an identical controller.
Note: When you use the hot-replace feature, some parameters (such as rebuild
rate) are not restored. If you have previously saved the controller
configuration, refer to it for information.
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.
Using Windows NT 4.0 with Active PCI features
To use Active PCI with Windows NT 4.0 and a ServeRAID controller, you must
install the following software components in this order:
1. DMI Service provider. A free version is included on the IBM ServeRAID Support
CD in the following directory:
e :\WINNT\DMISP\setup.exe
where e is the CD-ROM drive.
Note: This version is sufficient for most users’ needs, but a Y2K compliant
version is available at http://www.enablers.com/.
