Prerequisites for hot-plugging PCI adapters in a Linux partition

When you install, remove, or replace a PCI adapter in a Linux partition that is powered on, you might
need to complete some prerequisite tasks.
The Linux system administrator needs to take the PCI adapter offline prior to removing, replacing, or
installing a PCI adapter with the system power on (hot-plugging). Before taking an adapter offline, the
devices attached to the adapter must be taken offline as well. This action prevents a service representative
or user from causing an unexpected outage for system users.
Before hot-plugging adapters for storage devices, ensure file systems on those devices are unmounted.
After hot-plugging adapters for storage devices, ensure the file systems on those devices are remounted.
Before hot-plugging an adapter, ensure that the server or partition is at the correct level of the Linux
operating system (Linux operating system 2.6 or later).
