Solaris Transition Guide

Dynamic Reconfiguration

Dynamic reconfiguration, available on certain SPARC servers with the Solaris 7 release, allows a service provider to remove or replace hot-pluggable system I/O boards in a running system, eliminating the time lost in rebooting. Also, if a replacement board is not immediately available, the system administrator can use dynamic reconfiguration to shut down a failing board while allowing the system to continue operation.

See your hardware manufacturer's documentation for information about whether dynamic reconfiguration is supported on your server.
