Technote (troubleshooting)
Problem(Abstract)
The rpower or console commands are not able to connect with the other nodes in an IBM Smart Analytics System 5600 cluster, and report they cannot connect to the Baseband Management Controller (BMC) daemon.
Symptom
You may see the following errors when you run the rpower command:
bwlmgmt01:~ # rpower -a query
2659-103 [bwdata02] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwapp01] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwldata01] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwstdby02] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwdata07] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwdata10] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwstdby04] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwdata08] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwdata09] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwappstdby01] Internal error, could not connect to the bmc2 daemon.

2659-103 [bwstdby01] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwstdby03] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwadm01] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwdata05] Internal error, could not connect to the bmc2 daemon.
2659-103 [bwdata06] Internal error, could not connect to the bmc2 daemon.
Cause
The bmc2 daemon could have hung or terminated abnormally.
Resolving the problem
Use the following steps as root user to restart the bmc2 daemon:
- Stop the Hardware Control Resource Manager
stopsrc -s IBM.HWCTRLRM - Check that no bmc2 daemons are running
ps -ef | grep bmc2 - Terminate any bmc2 daemons using kill -9
- Start the Hardware Control Resource Manager
startsrc -s IBM.HWCTRLRM - Check if rpower is now able to connect to the nodes
rpower -a query
In the event that the bmc2 daemon is defunct and you are not able to terminate it in step 3, you may need to reboot the management server.
