Open File Button
This button allows you to load a currently saved FRU file. Upon selecting this option, all
currently loaded FRUs are deleted from the screen and the loaded FRU is displayed. If the file
to open is not a valid FRU file, this message is displayed:
Invalid FRU file
If there is an error while reading the FRU from the file, this message is displayed:
Error reading FRU from file
Opening a FRU file will not affect the FRU properties.
Properties Button
This button will display the system FRU properties in a dialog. Included in the properties are:
IPMI version, Number of FRUs in the system, and Number of IPMI formatted FRUs in the
system. There is also a note to notify you that only IPMI formatted FRUs are displayed.
Reload Button
This will clear the currently loaded FRUs and refresh the FRUs from the system. This load
procedure is identical to the load procedure when the viewer is opened.
Help Button
This displays the SMU context sensitive help for the FRU Viewer.
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 chapter 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 non-volatile 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.
