Dynamic reconfiguration (DR) is the ability to add or remove resources while the operating system is running. The ability to perform dynamic reconfiguration of a particular resource type is dependent on having support in the OS running in the logical domain.
Dynamic reconfiguration is supported for the following resources:
Virtual CPUs – Supported in all versions of the Solaris 10 OS
Virtual I/O devices – Supported in at least the Solaris 10 10/08 OS
Memory – Not supported
Physical I/O devices – Not supported
To use the dynamic reconfiguration capability, the Logical Domains dynamic reconfiguration daemon, drd, must be running in the domain that you want to change. See the drd(1M) man page.
