Operation
Issuing cpuconfig with no parameters displays the config/deconfig status of all processors. A user can
reconfigure CPUs by specifying a CPU number and a state (on or off). If a valid state is entered and is
different from the current state of a CPU, its status changes on the next boot. The last remaining configured
CPU in a server cannot be deconfigured.

Syntax
ioconfig <fast_init | wol> <on|off>
Parameters
<fast_init> specify device connection policy setting
<wol> specify system wake-on-lan setting
<on|off> specify to configure or deconfigure a feature or component
Operation
The ioconfig file is used to retain information on the server I/O configuration across reboots. The ioconfig
file is created by insf at install time; and is modified by insf, rmsf, and ioscan when devices are added or
removed. The only purpose of the ioconfig file to maintain configuration information when the system is
not running.
Example C-8 ioconfig Command
Shell> ioconfig
Deconfigure or reconfigure IO components or settings
IOCONFIG [fast_init|wol [on|off]]
fast_init Specifies device connection policy setting
wol Specifies System Wake-On-LAN setting
on|off Specifies to configure or deconfigure a feature or component
Note:
1. If fast_init is enabled, firmware will connect only the minimum set of
devices during boot. This feature might cause boot failure; disable this
feature if failure occurs.
2. Any pending Wake-On-LAN request will not be cleared until reboot if
the setting is changed to disabled.
System will clear pending Wake-On-LAN requests each time the system
reboots if the setting is disabled.
