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.
