Remote Dynamic Reconfiguration(DR) operation(from the System Controller), or local DR operation(from the domain), works fine until a DR operation does not respond; reporting in the $SMSLOGGER/domain_Id/messages file, messages like:
DCA/DCS communication error
dca[...]-S(): [... ERR DCSInterface.cc 378] message receive failed: DCSInterface :: receiveResponse errCode:502
In some cases, it may not be possible to kill the associated process(cfgadm, rcfgadm, deleteboard, showdevices).
Note: for background information on the DR mechanism, please refer to Document 1003582.1 (What Happens in a Sun Fire[TM] 15K/12K DR Slot0 Detach Operation).
Note: if none of the symptoms described below is true, and the signature of the rcm_daemon stack is not the same as described in this article, then it's more likely that you are facing a different issue. See the References section below for more troubleshooting steps.
