Using a ServeRAID-4x controller in a server with Hot-plug PCI features Some IBM 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-4x 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 Hot add Hot remove Hot replace Windows NT 4.0 Yes No Yes Windows 2000 Yes Yes No NetWare 4.x No Yes No NetWare 5.x Yes Yes 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-4x 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 server you are using. See "Downloadable files from the World Wide Web" on page 163 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 and configuring ServeRAID controllers 145
