HighWire MTP-2 - 1.2, September 4, 2002 Hot Plug Overview 13
2-3-1. Terminology
See the hardware-specific documentation of your Solaris system for details of
its System Configuration Administration support.
2-3-2. RCM overview The Reconfiguration Coordination Manager (RCM) is the framework that
manages the dynamic removal of system components. SBE HighWire
software packages supply a RCM script for releasing a board's daemon and
control device in an orderly manner. Applications using HighWire resources
must release their own resources during dynamic removal of HighWire
components. The RCM feature was added within the Solaris 8 4/01 release
and is also available on Solaris 9.
RCM commands are invoked only for the resources whose subsystems
participate within the RCM framework. Currently, not all Solaris subsystems
participate within this framework.

2-3-3. hw_daemon monitoring of
hardware status
The hw_daemon process continually monitors board availability as part of its
Hot Swap support. Upon board removal, re-insertion, and configuration, the
daemon will restart the SBE HighWire adapter without further administration
intervention.
