DR Model 3.0

DR 3.0 model offers the following enhancements over DR 2.0:

DR 3.0 has a framework that offers better integration with applications, through the Reconfiguration Coordination Manager.

DR 3.0 supports multi-pathing using IPMP.

You can execute DR operations from the system service processor (SSP) by using the SSP commands--addboard(1M), moveboard(1M), deleteboard(1M), cfgadm(1M), and showdevices(1M).

If you switch to DR 3.0 in a domain that is running the Solaris 8 SU6 operating environment, you must upgrade the SSP software to version 3.5. SSP versions 3.3 and 3.4 do not support DR 3.0 operations.
