With the last release of the Logical Domains Manager 1.2 software, we can easyly create LDoms with the Logical Domains Configuration Assistant (click here for the oficial documentation from docs.sun.com), running the ldmconfig command.
Be careful, it only works with systems where no existing logical domains configurations are present. It means that you must run it just after installing the Logical Domains Manager 1.2 software.
Basically, the assistant will configure the number of LDoms you want on your system, and automatically create the needed services.
So, let’s try it.
My configuration is :
- a T1000 with :
- Solaris 05/09 release,
- 24 vpcus (8 cores),
- 8 Gb RAM.
So after installing the Logical Domains Manager 1.2 software and before running the assistant, we are in the factory-default state, with all resources assigned to the primary domain :
The physical processor has 24 virtual processors (0-23)
UltraSPARC-T1 (chipid 0, clock 1000 MHz)
bash-3.00# prtconf | grep Mem
Memory size: 8064 Megabytes
bash-3.00#
bash-3.00# ldm ls
——————————————————————————
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.

Here is a video that will show the Logical Domains Configuration Assistant running :
And that’s it !
We have now 4 LDoms configured, with all the services needed as you can see :

Last step would be to install the LDoms…
NOTE : there is also a GUI as an alternative for the CLI ldmconfig. It is a jar file which comes with the LDom software 1.2, called Configurator.jar.
It requires Java 1.6 and can be run on a remote machine. Just indicate the IP of the Control Domain and the root password, the GUI will then do the rest for you, like ldmconfig.
The GUI looks like that :
Logical Domains Configuration Assistant (GUI)
Hope it can help you to rapidly deploy LDoms…
