PCI Hot Plug User's Guide 2.5.1

1.1 Feature Overview

PCI Hot Plug allows the user to physically remove or insert PCI cards while the operating system is still running. The user can modify the configuration of the system without shutting down the operating system. The typical applications are:

• Removal of PCI cards with faulty I/O device/controllers while the system is running.
• Addition of new PCI cards to expand the I/O capacity of the system while the system is running.

PCI Hot Plug can be used with hardware that offers Extended Partitioning (XPAR). Refer to "Partition Operation Guide" or "Dynamic Reconfiguration Architecture Guide".
The following models offer XPAR.
