The threading property has been removed from the Oracle VM Server for SPARC 3.3 release. Therefore, before you update your system to use the Oracle VM Server for SPARC 3.3 software, remove the threading=max-ipc property setting from all domains:
primary# ldm set-dom threading=max-throughput domain-name
If you do not remove this property setting, only one virtual CPU per core remains after the ldmd daemon is restarted and the whole-core constraint is lost.
Use the ldm set-core command to restore the whole-core constraint.
primary# ldm set-core n domain-name
