Using the Service Features
In addition to monitoring the library, LibMON allows you to initiate serial port commands to the library. These features are available only to admin level users.
The service features are supported by the following libraries:
- Sun StorEdge L1000
- Sun StorEdge L1800
- Sun StorEdge L3500
- Sun StorEdge L11000
Note - If you are using a library other than those listed above, you will not be able to use the service features.
To Connect the Server to the Library
Before you can use any of the service commands, you must connect the server to the library.
- Connect one end of a serial cable to the DIAGNOSTIC port at the back of the tape library.
- Connect the other end of the serial cable to a serial port on the server.
- Start LibMON and access the LibMON Home Page.
- Select the library.
- On the Selected menu, click Properties.
LibMON opens the Library Property Book Page for the selected library.
- In the Service Module section, make sure the serial port setting is valid for the serial port to which the library is connected. If not, change the setting.
The default setting is /dev/ttya.
- Click Apply to save any changes and exit the Library Property Book Page.
Note - If you move to another LibMON page without clicking Apply, any changes you have made will be lost.
To Place the Library Offline
- On the LibMON Home Page, select the library.
- On the Selected menu, click Library Offline.
LibMON displays a dialog box, prompting you to confirm the command.
- Click OK to place the library offline.
To abort the command, click Cancel.
LibMON places the library offline. When LibMON detects that the library is offline, it adds the event to the event management area and displays the library image against a red background.
To Place the Library Online
- On the LibMON Home Page, select the library.
- On the Selected menu, click Library Online.
LibMON displays a dialog box, prompting you to confirm the command.
- Click OK to place the library online.
To abort the command, click Cancel.
LibMON places the library online. When LibMON detects that the library is online, it adds the event to the event management area and displays the library image against a transparent background.
To Initiate an Actuator Self-Test
The actuator self-test sends a short electrical pulse to the extension axis, gripper, and drive door motors and then reads the encoder or sensor data associated with each motor. This operation is used to verify that these motors and their associated encoder or sensors respond as instructed.
- On the LibMON Home Page, select the library.
- On the Selected menu, click Library Selftest.
LibMON displays a dialog box, prompting you to confirm the command.
- Click OK to start the test.
To abort the command, click Cancel.
LibMON places the library offline (if necessary) and initiates the actuator self-test.
When the test is complete, LibMON returns all the axes to their home positions, and returns the library to the state it was in (online or offline) when the command was initiated.
To Download New Firmware to the Library
Caution - Be careful when performing this procedure. If you download the wrong firmware file, the library may be rendered temporarily unusable.
Note - Before initiating a firmware download, shut down all processes (except LibMON) that issue SCSI requests to the library. This includes storage software products. Failure to stop these processes may cause the firmware download to fail.
- Copy the firmware file onto the server (the recommended directory is /opt/SUNWlmon/service_module/firmware).
The file must have the extension .hex.
- On the LibMON Home Page, select the library.
- On the Selected menu, click Firmware Download.
LibMON displays the Firmware Download File Selection dialog box, prompting you to select the desired firmware file.
- Select the file:
- The Known Files list displays all the firmware files in the /opt/SUNWlmon/service_module/firmware directory and subdirectories. If the firmware file is in this directory, select the check box next to Known Files and select the desired file from the list box.
- If the firmware file is not in the /opt/SUNWlmon/service_module/firmware directory, select the check box next to Full Path, and then type the full path and file name in the Full Path field.
- Click OK to exit the dialog box.
LibMON displays a dialog box, prompting you to confirm the download.
- Click OK to start the firmware download.
LibMON places the library offline (if necessary) and initiates the firmware download. The Firmware Download Progress dialog box graphically displays the progress of the download.
- To close the Firmware Download Progress dialog box before the download is complete, click OK.
Note - Closing the Firmware Download Progress dialog box does not interrupt the firmware download.
When the download is complete, the Firmware Download Progress dialog box automatically disappears and LibMON displays a dialog box prompting you to cycle power to the library.
- Turn the library off, and then turn it back on.
This completes the firmware download operation.
