hot plug

The first mapping stage takes the hotplug group name and outputs the kernel-assigned interface name if the interface is to be hot plugged.

One or more agent types, with the name type. agent, can be invoked for a hotplug event.

The scripting framework is referred to as hotplug policy agents.

A hotplug event can be used to invoke an agent task to configure an adapter, subsystem, or program.

From RHEL4 onwards, Linux employs the concept of hotplug-subsystem udev.

IDE drives are limited to 63 partitions on systems that do not use hotplug support for IDE drives.

The change of name for IDE drives is a result of the hotplug system, which initially supported USB drives.

Create a hotplug script to detect dynamic changes to PCI adapters or processor resources in a partition.

The recommended approach for 16 bit cards takes advantage of the fact that the Linux 2. 4 Hotplug subsystem now supports PCMCIA .

Later if the hardware is removed then the kernel runs hotplug again with different environment variable settings.

When the kernel detects new hardware it initializes the driver for the hardware and then runs the hotplug program to configure it.

Dynamic LPAR event scripts can use standard hotplug event script programming techniques.

PCI hotplug (of which there are several specifications) is one aspect that needs to be addressed.

This script will be invoked for dynamic LPAR CPU change events, with the hotplug actions online and offline.

Ifupdown controlled by hotplug with pcmcia-cs confined to loading modules.

Hotplug support for devices became a standard feature on Linux starting with the kernel 2. 4.
