Using a ServeRAID controller in a server with Hot-plug PCI features
Some IBM Netfinity servers support Hot-plug (Active) PCI features. You can use
these features to install or remove PCI controllers without turning off the server. The
ServeRAID-4H controller supports Hot-plug 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
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 Hot-plug PCI features
To use Hot-plug PCI with Windows NT 4.0 and a ServeRAID-4H controller, you
must install the IBM Netfinity 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 Netfinity server you are using. See “Downloadable files from the
World Wide Web” on page 14 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 Netfinity 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.
Note: It is useful to start the IBM ServeRAID Hot Replace Wizard from a remote
installation when the server with the failed controller does not have a
monitor.
Attention: Do not attempt a hot-replace operation on Windows 2000 or NetWare
by hot- removing a failed controller; 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.
Installing the ServeRAID controller
During the installation, you might need a small, flat-blade screwdriver and the
documentation that comes with your server.
To install the ServeRAID-4H controller:
1. Review “Safety Information” on page vii and the Safety Information book
provided with your Netfinity server.
