8.7 Ordered Shutdown of Logical Domains

8.7 Ordered Shutdown of Logical Domains
In the SPARC M12/M10 systems, you can perform an ordered shutdown of all the logical domains from the XSCF. For details on how to start an ordered shutdown, see the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide.
You can change priorities in the shutdown by setting shutdown group numbers for the logical domains with the ldm command.
The logical domains are shut down in descending order of shutdown group number. In other words, the domain with the highest number is shut down first. The domain with the lowest number is shut down last. If multiple domains share a common priority, they are shut down at the same time unless there is a master-and-slave relationship. In that case, the slave domains are shut down before the master domain.
For details on how to set the master and slave, see the Oracle VM Server for SPARC Administration Guide.
The effective values are 1 to 15. The shutdown group number of the control domain is 0 and cannot be changed. The default value for other domains is 15.
# ldm set-domain shutdown-group=8 secondary
Suppose that all other guest domains have the default shutdown group number. Then, an ordered shutdown would shut down all these other guest domains first, the secondary domain after that, and the control domain last.
As an example, the set shutdown group number for a domain named "secondary" is not the default value.
Note - You can set the shutdown-group property when a logical domain is in any of the inactive, bound, and active states. Also, when creating a new logical domain, you can set its properties too. However, to enable an updated shutdown priority, the XSCF must recognize the new property values.
To have the XSCF recognize the set property values, set each domain to the bound or active state, and then use the ldm add-spconfig command to save the logical domain configuration information. After that, power on the server again so that the XSCF recognizes the values.
