command. At this time, a single domain will be running on the server that owns
all of the installed memory and CPUs.
The following example is taken from a small (6-core) T1000. The warning that
the system is in configuration mode is displayed after each
ldm
command until
the system is rebooted with the new configuration. For brevity, we will omit the
subsequent identical warning messages.

Notice: the LDom Manager is running in configuration mode. Configuration and resource
information is displayed for the configuration under construction; not the current
active configuration. The configuration being constructed will only take effect after it
is downloaded to the system controller and the host is reset.

Because the control domain initially owns all hardware resources, it must be re-
sized to provide the RAM and CPUs to be allocated to guest domains. Essential
services for providing virtual disk, network, and consoles should be defined now as
well. When the domain is rebooted, it will have the specified number of CPUs and
amount of RAM. The remainder of those resources will be available for allocation
to guest domains. The sequence will look similar to this sequence:
