Dynamic Reconfiguration

Dynamic reconfiguration (DR) enables resources to be added or removed while the operating system (OS) is running. The capability to perform DR 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 Oracle Solaris 10 OS and the Oracle Solaris 11 OS

• CPU whole cores – See Oracle Solaris OS Versions in Oracle VM Server for SPARC 3.6 Installation Guide

• Virtual I/O devices – Supported in at least the Oracle Solaris 10 10/08 OS and the Oracle Solaris 11 OS

• Memory – See Using Memory Dynamic Reconfiguration

• Physical I/O devices – Not supported

To use the DR capability, the Logical Domains DR daemon, drd, must be running in the domain that you want to change. See the drd(8) man page.
