5.3.1.3 Configuration Information
Information about the PCI adapters can be obtained by running the

lscfg

command.

To determine how much memory you have in your machine, run the following
command:

lsattr -El mem0

This will show the size of memory in your machine and how much usable
memory there is.

You can also see the size of the L2 cache installed in your system by using
the

lsattr

command:

lsattr -El L2cache0

5.3.2 PCI Adapter Configuration

If the required device drivers are installed, PCI adapters are configured
automatically at system restart or by using the

cfgmgr

command.

When you install the AIX operating system, it will query the PCI bus to identify
all AIX supported adapters. The installation process will install the required
device drivers and diagnostic support (if available), and the system will
automatically configure the PCI adapters.

If you have a system installed and running, you can use

smit cfgmgr

. This

method will require you to put the AIX installation media in place (CD-ROM,
tape, and so forth) before configuring the adapters. The media will be used
only if the device drivers for your adapters are not currently installed.

You can also manually install the device drives and diagnostics before
running

cfgmgr

or rebooting the system for automatic PCI adapter

configuration.

When using PCI adapters, the slot number is important. If you change an
adapter from slot A to slot B, the original adapter information for slot A will be
kept in a

defined

state; a new definition will be created for slot B, and a new

device will be configured.

5.3.2.1 Configuring Non-Graphic PCI Adapters
Configuring PCI adapters is very easy because they are actually configured
automatically when their driver software is installed and the

cfgmgr

command

is run.
