E.6.1 Restoration Method When Correct Information is not Distributed to All the Nodes

If communication is not available in other nodes when Configuration Update Service for SA operates, the configuration file for the shutdown agent is not distributed to other nodes.

In this case, consistency of the information stored in each node is not ensured and the shutdown agent cannot operate normally.

The following example shows the restoration methods in such a case.

If distribution of the configuration file for the shutdown agent to nodeB fails because the BMC IP address of nodeA is changed and nodeB is stopped:

nodeA: 10.20.30.41 -> Changed to 10.20.30.51
nodeB: 10.20.30.42 (Stopped)
nodeC: 10.20.30.43

Checking the message

On nodeA, for which the BMC IP address is changed, check that any of the following messages are output on syslog.

sfsacfgupdate: ERROR: Failed to copy the backup of <file> on node <node>.

sfsacfgupdate: ERROR: Failed to distribute <file> to node <node>.

sfsacfgupdate: ERROR: Failed to change the access permission of <file> on node <node>.

sfsacfgupdate: ERROR: Failed to change the group of <file> on node <node>.

sfsacfgupdate: ERROR: Failed to change the owner of <file> on node <node>.

If any of the above messages are output, the process for <node> has failed.

Checking the stopped node
If all the other nodes stop while Configuration Update Service for SA is operating, messages in Step 1 are not output. Check if any nodes stop.
Restoring the stopped node
Check that the status of the stopped node and restore it.

Checking the current status

Execute the following command on any node to check the current status.

# /opt/SMAW/SMAWsf/bin/sfsacfgupdate -s
Node : nodeA
 Node status : UP
 Configuration Update Service status : ENABLE
 BMC IP Address :
  10.20.30.51 <- Changed from 10.20.30.41
 Configuration file :
  nodeA 10.20.30.51  <- Updated with the changed information on nodeA
  nodeB 10.20.30.42
  nodeC 10.20.30.43

Node : nodeB
 Node status : UP
 Configuration Update Service status : ENABLE
 BMC IP Address :
  10.20.30.42
 Configuration file :
  nodeA 10.20.30.41 <- Not updated with the changed information on nodeB
  nodeB 10.20.30.42
  nodeC 10.20.30.43

Node : nodeC
 Node status : UP
 Configuration Update Service status : ENABLE
 BMC IP Address :
  11.22.33.46
 Configuration file :
  nodeA 10.20.30.51 <- Updated with the changed information on nodeC
  nodeB 10.20.30.42
  nodeC 10.20.30.43

In the above example, you can see the BMC IP address of nodeA is not updated with the changed information in the configuration file for the shutdown agent stored in nodeB.

Restoring the information
Execute the following command on a node storing the correct information to restore the status.
In this case, execute the command on nodeA or nodeC because the information stored in nodeA and nodeC is correct.
```
# /opt/SMAW/SMAWsf/bin/sfsacfgupdate -r
```

Checking the status after restoration

Execute the following command on any node to check the current status.

In the following example, you can see the BMC IP address of nodeA is updated with the changed information in the configuration file for the shutdown agent stored in nodeB.

# /opt/SMAW/SMAWsf/bin/sfsacfgupdate -s
Node : nodeA
 Node status : UP
 Configuration Update Service status : ENABLE
 BMC IP Address :
  10.20.30.51
 Configuration file :
  nodeA 10.20.30.51
  nodeB 10.20.30.42
  nodeC 10.20.30.43

Node : nodeB
 Node status : UP
 Configuration Update Service status : ENABLE
 BMC IP Address :
  10.20.30.42
 Configuration file :
  nodeA 10.20.30.51 <- Updated with the changed information on nodeB
  nodeB 10.20.30.42
  nodeC 10.20.30.43

Node : nodeC
 Node status : UP
 Configuration Update Service status : ENABLE
 BMC IP Address :
  11.22.33.46
 Configuration file :
  nodeA 10.20.30.51 
  nodeB 10.20.30.42
  nodeC 10.20.30.43
