Each of the three methods has similarities and
differences and a chapter is devoted to each method, as well as an
additional chapter with flowcharts showing all of the methods together
for comparison and to act as a quick reference. “Mixing OL* Methods” includes a table, which details
the consequences of mixing OL* methods.
Peripheral
Device Tool |

The Peripheral Device Tool (pdweb) is an easy-to-use, powerful peripheral device management
solution delivering a Web-enabled graphical user interface (GUI).
This tool allows system administrators to view all devices on a
host system and configure the slots and cards for that system. It
is an easy-to-use GUI that steps system administrators through the
entire process of card addition/replacement. The Peripheral Device
Tool operates in a single-system environment.
The official name of this method of is Peripheral Device Tool,
though pdweb will be used in this document to describe the tool, and pdweb will be used to denote the command itself.
The Peripheral Device Tool can be launched from a Web browser,
from the System Administration Manager (SAM) tool, or from Service
Control Manager (SCM) version 3.0 or greater. Additionally, pdweb functionality is accessed directly by the Partition Manager
(parmgr) tool providing a link between two tools for your convenience.
Additional information regarding the Peripheral Device Tool
is available from the various help links within the tool, including
the online help system, related documentation, product support services,
and other online resources, refer to the assistance topic.

The Peripheral Device Tool GUI provides system administrators
these key features and benefits:
Features
Viewing detailed
information about cards, devices and slots, including all available
PCI/OL* slots in an easy-to-read format.
Adding and/or replacing a
card without shutting down the host system.
Creating special device files
dynamically.
Generating a Critical Resource
Analysis report that lists resources lost if a slot is powered down.
These resources are grouped by their impact on the system.
Bringing cards online without
shutting down the host system.
Blinking or extinguishing
the Attention LED of any slot that support online actions.
Previewing commands that
support the GUI actions, prior to execution.
Benefits
Performance
improvements over previous pdweb implementations, actions that took a minute or more now
take only a few seconds.
Smart OL* technology takes
advantage of the feature that only allows a matching replacement
card to be brought online.
A Fast Web interface is light
on the network and can be used in places where an X-Windows interface
is not available or does not provide equivalent speed.
Additional Web Security provides
a secure, encrypted connection between the Web browser and the host system.
Attention
Button |
|
OL* compatible slots feature an OLX Divider that contains
a power LED, an attention LED, and an Attention Button. Attention
Button is the method used for hardware triggered Hot-Plug operations,
with minimal or no console interactions.
Initially, not all platforms will have this capability, but
over time users should see many systems adding this capability to
their set of functions. See the system documentation for details
on the slot, OLX Divider and Attention Button capabilities.

 | NOTE: Although
Attention Button is used throughout this document, it is also known
by other names, including DoorBell, hotplug, and Attention Indicator. |

olrad
Command |
|
The olrad command provides the ability to perform command
line based online addition and replacement of I/O cards. olrad performs critical resource analysis of the system
before performing any OLA/R operation to ensure that the system
is not left in an inconsistent state after a PCI card is added/replaced.
