Symptoms

The rcfgadm or showdevices commands, generate errors from the system controller (SC). The error message might be "DCA/DCS Communication Error" when executing these commands. The command showdevices might generate the following error (where x is the domain ID):

# showdevices -v -d x
Unable to get device information from domain x

This showdevices error could also be seen in Explorer data from the Main System Controller (SC).  The file, showdevices_-v_-d_x.out, which is in the /explorer/sf15k/ directory of Explorer will show the same "Unable to get device information from domain x" error message.

Also the following messages might be logged in the platform log file on the SC ( $SMSVAR/adm/platform/messages )

xcat-sc0 showdevices[7496]: [0 2197706244444996 ERR ri_init.cc 85] rcfgaRequestProxy->ri_init failed. Status= 4315
