Task Error Handling

During the execution of a task, it is possible for errors to occur. These errors may be handled in
different ways depending on the type of error. This section describes how error handling operates
during SMU task execution.

Data Entry Errors

Some screens will ask for user input using edit boxes. In some of these boxes, the allowable user
input needs to meet certain requirements, such as use of certain characters, a maximum length, or
data within a particular range of values. The application does not check user input for validity;
instead, when you click a button for the next screen, the current set of data is collected and sent to
the SMU core components where it is checked. If a data entry error is found, a popup dialog box is
displayed describing the error. In most cases the erroneous data is not cleared from the edit box in
which it was entered. The user must clear the error and enter the correct information.

Internal Errors For Which a View Can Be Generated

Some errors may occur during task execution that result in an operation failing but are not fatal in
that you can still attempt to perform other tasks. These types of errors include writing the server
management settings to the BMC's nonvolatile storage area, for example. In such a case, a screen
is displayed containing information about the error that occurred and indicating whether or not you
may attempt the operation again. These screens also have an OK button on them. When you click
OK, the last screen displayed is redisplayed. You may also be informed as to whether the error was
serious enough that you should shut down the SMU software or reboot the server.

Data Corruption Errors that the SMU Application Can Handle

Data corruption errors that the SMU may be able to handle include corruption of template files used
by the SMU (files that represent UI screens to be sent from the core components to the application).
In this type of case, the SMU can detect that there is a problem when it is not able to correctly parse
such a file, which means the application is not able to correctly display a screen. For this type of
error, a message is displayed, indicating that a data corruption error has been encountered and that
the current action cannot be completed. You are asked to select a new task from the task list.

Internal Errors For Which a View Cannot Be Generated

In a few cases, errors may be serious enough to prevent the SMU core components from supplying
error information to you. These errors may include certain types of memory allocation errors or, in
the remote case, the loss of the connection between the SMU application and the core components.
In such cases, the SMU application (if possible), indicates to you that a shutdown of the software
should occur and the server be rebooted.
