Server workflows for HP Matrix Operating Environment

29
Once the information is collected, the following operations can be supported on the new server:
 Get Inventory
 Get Server Info
 Server Power ON
 Server Power OFF
The following subsections explain implementation details of adding these operations for the new server. It is a
summarization of information noted earlier in the Extensibility section of the discussion of each workflow.
Get Inventory operation
In order to support Get Inventory operation, the UUID of the new server must be added into inventoryList.xml file. After
the inventoryList.xml file is updated with the new UUID, the subsequent calls to Get Inventory operation will retrieve
the new server’s UUID.
No additional changes are required in the current implementation to support Get Inventory operation for the new
server.
Get Server Info operation
The new server data must be added to the serverInfo.xml file.
If the new server remote management interface supports a command to get the power status, then a new logic needs
to be implemented in a subflow. In order to invoke the power status command on the remote management interface,
the IP address of the remote management interface should be added into uuidHostMapper.xml file. However, if the
power status command is not supported on the remote management interface, no additional changes are required to
the current Get Server Info implementation.
The following steps explain how to add a new subflow and modify the existing implementation:
 Implement the logic to retrieve the power status of the server
o Make sure that the new subflow will receive all necessary input parameters:
 IP Address of the remote management interface
 If necessary, add login (username/password) credentials into OO System Accounts
 Command to execute
 Any other parameters to fulfill the flow logic
o Ensure the implemented logic will give the result (true or false) in the form of string into the result field
parameter.
 true indicates that server power is ON
 false indicates that server power is OFF
 Once the new subflow is implemented and tested, it can be called by modifying the subflow “Update Server
PowerOn Status”.
o Add a string comparator to compare the new server model. If matches, call the new subflow logic to get the
power status from the new server.
o Add the newly implemented subflow as a step operation upon matching the server model.
 Provide all necessary inputs to the new subflow operation added.
 Define the result field parameter of the subflow operation by name CmdOutput. This will hold the result
of the logic implemented to get the power status of the new server.
o The successful transition should invoke “UpdateServerInventoryFile” operation.
o The failure transition should return back to the ListIterator.
