PCI Adapters
Attention: The Linux operating system does not support some hot-pluggable procedures. Also, Linux
does not support hot-plugging any hot-pluggable PCI adapters or devices. A system with Linux installed on
one or more partitions must be shutdown and powered off before replacing any PCI adapter or device
assigned to a Linux partition. Follow the non-hot-pluggable adapter or device procedures when replacing a
PCI adapter or device in any partition with Linux installed.
Most PCI adapters can be removed and replaced, or installed in the system without turning off the power
to the entire system. These adapters are referred to as hot-pluggable PCI adapters . Some adapters are
not hot-pluggable and power must be removed from the system for adapter removal, replacement, or
installation.
Note: An adapter or an adapter blank filler must be installed into the PCI adapter cassette assembly
before it is reinstalled in a system unit or an I/O drawer.
Before you remove or replace an adapter, determine if the PCI adapter you are working with is
hot-pluggable. See the PCI Adapter Placement Reference , order number SA38-0538.
If you are installing or removing a PCI adapter that is:
v
Not hot-pluggable, go to “Non-Hot-Pluggable PCI Adapter Removal and Replacement” on page 60.
