This feature is new in the Software Express pilot program and in the Solaris 9 4/03 release. This feature is included in the Solaris 10 3/05 release.
Reconfiguration Coordination Manager (RCM) support adds to Solaris Volume Manager the ability to respond appropriately to dynamic reconfiguration (DR) requests. This addition ensures that removal of devices under Solaris Volume Manager control is blocked with an appropriate warning. This block remains in effect until the devices are no longer in use. This warning prevents system administrators from accidentally removing active volumes from a DR-configured system.
For further information, see the Solaris Volume Manager Administration Guide.
