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

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.
