How do I start LDOM?
How to Start a Domain

What is LDOM in Solaris?
Solaris LDom Virtualization Technology. Solaris LDoms is a server virtualization and partitioning technology that is used by many enterprises to host multiple instances of Solaris or Linux virtual machines (VMs) on a Sun server.
What is Cdom and LDOM?
Virtualized Infrastructure. With each control domain (CDOM) are virtualized guest domains, referred to as logical domains (LDOM) or, simply, guests. Operating system instances and applications run in these guests, supported by the hypervisor’s virtual I/O devices.
What does LDOM stand for?

What is control domain in Solaris?
The control domain is an administrative control point that runs Solaris or OpenSolaris and the Logical Domain Manager services. It has a privileged interface to the hypervisor, and can create, configure, start, stop, and destroy other domains.
How do I save my LDOM config?
Save Domain Configurations
- To save the configuration for a single domain, create an XML file containing the domain’s constraints. # ldm list-constraints -x ldom > ldom .xml.
- To save the configurations for all the domains on a system, create an XML file containing the constraints for all domains.
How do I log into LDOM console?
Based on the above port range, the Guest LDom will be allocated a VCC port id. Now you can connect to the virtual console of your guest domain by using telnet and the console number specified under the Cons column from above: # telnet localhost 5000 Trying 127.0. 0.1 Connected to localhost.
How do you stop LDom?
Gracefully Shut Down LDoms
- Shut down, stop, and unbind each of the non-I/O domains. # ldm stop domainname LDom domainname stopped # ldm unbind-domain domainname.
- Shut down, stop, and unbind any active I/O domains. # ldm stop activedomainname LDom activedomainname stopped # ldm unbind-domain activedomainname.
- Halt the primary domain.
How do I check my LDom list?
Option:1
- Login to ILOM and to find the physical memory of the server. (#value1)
- Use the “ldm list” to know the currently allocated memory for primary domain and guest domains.(#value2)
- Subtract the physical memory from allocated memory. ( Un-allocated memory= value1-value2)
How do I add a disk to LDom?
Managing Virtual Disks
- Export the virtual disk backend from a service domain. # ldm add-vdsdev [options={ro,slice,excl}] [mpgroup= mpgroup ] backend volume_name@service_name.
- Assign the backend to a guest domain. # ldm add-vdisk [timeout= seconds ] disk_name volume_name@service_name ldom.
