System Management Guide: Operating System and Devices

Removing or Replacing a PCI Hot Plug Adapter

This section provides procedures for removing a PCI hot plug adapter. You can complete these tasks with Web-based System Manager. You can also use SMIT or system commands. To perform these tasks, you must log in as root user.

You can remove or replace a PCI hot plug adapter from the system unit without shutting down the operating system or turning off the system power. Removing an adapter makes the resources provided by that adapter unavailable to the operating system and applications.

Replacing an adapter with another adapter of the same type retains the replaced adapter's configuration information and compares the information to the card that replaces it. The existing device driver of the replaced adapter must be able to support the replacement adapter.

For additional information, see PCI Hot Plug Management in the AIX 5L Version 5.1 System Management Concepts: Operating System and Devices.


Before you can remove an adapter, you must unconfigure it. See Unconfiguring Communications Adapters, Unconfiguring Storage Adapters, or Unconfiguring Async Adapters for instructions for unconfiguring adapters.
