Adding a PCI Hot Plug Adapter
This section provides procedures for adding a new PCI hot plug adapter.
Attention: Before you attempt to add PCI hot plug adapters, refer to the PCI Adapter Placement Reference, shipped with system units
that support hot plug, to determine whether your adapter can be hot plugged.
Refer to your system unit documentation for instructions for installing or
removing adapters.
You can add a PCI hot plug adapter into an available slot in the system
unit and make new resources available to the operating system and applications
without having to reboot the operating system. The adapter can be another
adapter type that is currently installed or it can be a different adapter
type.
Adding a new PCI hot plug adapter involves the following tasks:
- Finding and identifying an available slot in the machine
- Preparing the slot for configuring the adapter
- Installing the device driver, if necessary
- Configuring the new adapter
You can complete these tasks with Web-based System Manager. You can also use SMIT
or system commands. To perform these tasks, you must log in as root user.
For additional information, see PCI Hot Plug Management in the AIX 5L Version 5.2 System Management Concepts: Operating System and Devices.
Note
When you add a hot plug adapter to the system, that adapter
and its child devices might not be available for specification as a boot device
using the bootlist command. You might be required to
reboot your system to make all potential boot devices known to the operating
system.
SMIT Fastpath Procedure
- Type smit devdrpci at the system prompt, then
press Enter.
- Use the SMIT dialogs to complete the task.
To obtain additional information for completing the task, you can select
the F1 Help key in the SMIT dialogs.
Commands Procedure
You can use the following commands to display information about PCI hot
plug slots and connected devices and to add a PCI hot plug adapter:
- The lsslot command displays a list of all the hot
plug slots and their characteristics. For information about using this command,
see lsslot in the AIX 5L Version 5.2 Commands Reference, Volume 3.
- The lsdev command displays the current state of
all the devices installed in your system. For information about using this
command, see lsdev in the AIX 5L Version 5.2 Commands Reference, Volume 3.
- The drslot command prepares a hot plug slot for
adding or removing a hot plug adapter. For information about using this command,
see drslot in the AIX 5L Version 5.2 Commands Reference, Volume 2.
For information about installing or removing adapters, refer to your system
unit documentation.
