Using Active PCI features

Notes: This action is not supported when using the following:

  1. Integrated RAID controller
  2. ServeRAID-5i controller
  3. ServeRAID-6i/6i+ controller
  4. ServeRAID-6M controller under Windows operating systems

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 following table summarizes which operating systems support these features.

Feature Windows NT 4.0 Windows 2000 Windows Server 2003 NetWare 4.x NetWare 5.x
Hot add Yes Yes Yes No Yes
Hot remove No Yes Yes Yes Yes
Hot replace Yes No No No No

You can use the hot-add feature to add a controller to a running server, thus expanding its capacity.

Note: If you are not using the hot-add feature, restore the controller to the factory-default settings before configuring arrays and logical drives.

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.

Attention: Do not attempt a hot-replace operation on Windows 2000, Windows Server 2003, 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.
