After the next reboot of the OS
After a stop and start of a logical domain if no OS is running
In general, delayed reconfiguration operations are restricted to the control domain. For all other domains, you must stop the domain to modify the configuration unless the resource can be dynamically reconfigured.
Delayed reconfiguration operations are restricted to the control domain. You can run a limited number of commands while a delayed reconfiguration on the root domain is in progress to support operations that cannot be completed dynamically. These subcommands are add-io, set-io, rm-io, create-vf, and destroy-vf. You can also run the ldm start-reconf command on the root domain. For all other domains, you must stop the domain to modify the configuration unless the resource can be dynamically reconfigured.
While a delayed reconfiguration is in progress, other reconfiguration requests for that domain are deferred until it is rebooted or stopped and started.
The ldm cancel-reconf command cancels delayed reconfiguration operations on the domain. For more information about how to use the delayed reconfiguration feature, see the ldm(1M) man page.
You can use delayed reconfiguration to decrease resources on the control domain.
