Logical Domains 1.2 Release Notes

ldmd Shows Domain State as transition When the Domain Is Running After a CPU DR Operation

Bug ID 6816969: A domain can sometimes be marked as being in transition mode even though it is booted. Transition mode is the mode in which a Solaris domain is booting or shutting down. CPU Power Management does not occur on a system when any domain is in transition mode. If a domain remains in transition mode, CPU Power Management will not occur when load is added to any domain.

Workaround: Switch from elastic mode to performance mode. If you want to return to elastic mode, reboot the domain that is stuck in transition mode.
