When you turn on the SAN Volume Controller, the system board performs self-tests. During the initial tests, the hardware boot symbol is displayed.
All SAN Volume Controller models perform a series of tests to check the operation of components and some of the options that have been installed when the units are first turned on. This series of tests is called the power-on self-test (POST).
If a critical failure is detected during the POST, the SAN Volume Controller software is not loaded and the system error LED on the operator information panel is illuminated. If this occurs, use MAP 5000: Start to help isolate the cause of the failure.
When the SAN Volume Controller software is loaded, additional testing takes place, which ensures that all of the required hardware and software components are installed and functioning correctly. During the additional testing, the word Booting is displayed on the front panel along with a boot progress code and a progress bar.
If a test failure occurs, the word Failed is displayed on the front panel along with a boot progress code. Some parts of the boot process take several minutes to complete. If the progress bar fails to move and the boot code number does not change for several minutes, see the boot progress code section to understand the situation.
The service controller performs internal checks and is vital to the operation of the SAN Volume Controller. If the error (check) LED is illuminated on the service controller front panel, the front-panel display might not be functioning correctly and you can ignore any message displayed.
The uninterruptible power supply also performs internal tests. If the uninterruptible power supply is capable of reporting the failure condition, the SAN Volume Controller displays critical failure information on the front-panel display or sends noncritical failure information to the cluster error log. If the SAN Volume Controller cannot communicate with the uninterruptible power supply, it displays a boot failure error message on the front-panel display. Further problem determination information might also be displayed on the front panel of the uninterruptible power supply.
If a critical failure is detected during the tests, the SAN Volume Controller 2145-4F2 software is not loaded and no additional fault information is provided. When the SAN Volume Controller 2145-4F2 software is loaded, additional testing is performed. This testing ensures that all the required hardware and software components are installed and functioning correctly. During this portion of the testing, the word Booting displays on the front panel along with a boot progress code and a progress bar.
If a test fails, the word Failed displays on the front panel. You can use the progress code to isolate the cause of the problem. If the booting progress bar fails to move to the right for two minutes, the test process is hung. Use the boot progress code to isolate the failure.
The service controller performs internal checks and is vital to the operation of the SAN Volume Controller 2145-4F2. When an internal check fails, the SAN Volume Controller 2145-4F2 does not operate. Ignore other front-panel indicators when you see that the check LED is illuminated.
The uninterruptible power supply also performs internal tests. If the uninterruptible power supply is capable of reporting the failure condition, the SAN Volume Controller displays critical failure information on the front-panel display or sends noncritical failure information to the cluster error log. If the node cannot communicate with the uninterruptible power supply, it displays a boot failure error message on the front-panel display. Additional problem determination information might also be displayed on the front panel of the uninterruptible power supply.
