Figure 28: Flow diagram of operational details
This flow diagram can also be used to trace any issues and to determine which log file to look at for
failure events.
1.
Lock Managed Node.
This is an SAP ACC operation to lock any other ACC operations for the specific Managed
Node, to ensure that only one operation will be performed on any node at any time. If some
other node is already performing an operation, the new request will be on hold until the
previous operation complete.
For any errors during this step, see the SAP ACC log files for the specific instance and operation.
2.
Check OpenSSH to Managed Node.
This is an SAP ACC operation to ensure communication with the managed Node exists and is
working. If the Managed node cannot be reached, the node will be considered down and the
operation will fail.
