LDoms 1.3 bits now on pkg.opensolaris.org

The LDoms 1.3 packages are now available in the OpenSolaris repositories.


To install or upgrade just type

pfexec pkg install ldomsmanager

If you previously had LDoms 1.2 installed from an IPS repository, you will then need to restart the LDoms Manager (any existing configs will work just fine).

svcadm restart ldmd

If you were previously running the SVR4 version of the SUNWldm package, you will need to uninstall this before running pkg install

Switching between ALOM and ILOM shells

Here are the commands needed to switch between the ALOM and ILOM shells on the T5xx0 SPARC CMT servers. I'm saving this here because I can never easily find it when I go searching Google or docs.sun.com for it.

ALOM -> ILOM
sc> userclimode admin default
sc> logout

ILOM -> ALOM
-> set /SP/users/admin cli_mode=alom
-> exit

And usually when I want to do this, it's because I'm switching on Power Management

To set the policy property to elastic mode (enable PM):

-> set /SP/powermgmt policy=elastic

To set the policy property to performance mode (disable PM):
-> set /SP/powermgmt policy=performance

LDoms 1.2 in OpenSolaris IPS repos

For anyone running OpenSolaris (either 2009.06 or the latest 2010.02 development builds), you'll be glad to know that I've pushed the LDoms 1.2 software to the /release and /dev repositories. You can get it by running:

pfexec pkg install ldomsmanager

If you were previously running LDoms 1.1 from the IPS repo, the new version will start running once you do a 'svcadm restart ldmd'.

If you were previously running LDoms 1.2 or earlier which was installed via pkgadd, then do a 'pkgrm SUNWldm' before the pkg install (your existing LDoms configs will be kept).

LDoms Migration demo

I notice that Markus Weber has posted a  slick demo he produced which shows a warm migration of an LDom from one system to another while Solaris keeps on running in the domain. He gives a good overview of how domain migration works on LDoms as well as showing the command-line instructions.

Presentation on LDoms at the London OpenSolaris User Group

I'm giving a presentation at the next meeting of the London OpenSolaris User Group on Wed Oct 17th at Sun's Customer Briefing Centre, 45 King William Street (map here) - refreshments are from 18:00 with the presentation starting at 18:45. I plan to give an introduction to LDoms, an recap of the just released LDoms 1.0.1 plus a quick overview of some of the upcoming features. 

About

I have been working in Sun/Oracle since 1998 and I've spent much of that time working on adding Solaris support for various SPARC processors and servers. For the last 6+ years I've been working on what is now known as Oracle VM Server for SPARC (previously called LDoms) – virtualisation support for servers based on UltraSPARC CMT processors.
