Solution 1509740.1 : 2540-M2, 2530-M2 Array Controller 7-Segment Display Reports 0F Code.

Applies to:

Sun Storage 2540-M2 Array - Version Not Applicable to Not Applicable [Release N/A]
Sun Storage 2530-M2 Array - Version Not Applicable to Not Applicable [Release N/A]
Information in this document applies to any platform.

Symptoms

One, (or both) of the 2500-M2 controllers is in a non-operational state. Visual inspection of the array shows that the 7-segment display for the controller is not reporting the tray ID. Instead the display returns a code of 0F.

The Controller shell interface is also unresponsive. You will be able to access the shell, but unable to execute any commands. For example...

-> loadDebug
   C interp: unknown symbol name 'loadDebug'.

-> tt"tRaid"
   tt(): task not found
   value = -1 = 0xffffffff

Cause

0F indicates the controller stopped its boot sequence in the Application Start phase. There may be various causes of the problem.

Solution

This issue must be resolved by Oracle Support. Please open a Service Request to obtain assistance.

For TSC L2 engineers:

Part A. Data Collection

1. Connect to the controller serial port reporting the "0F." Boot controller.

2. Collect the console output while the controller starts and reports the "0F" on the 7-segment display.

3. Enter the Boot Operation Menu and print out the "Change Hardware Configuration Menu" variables.

    password: {oracle-only}
    -> M

NOTICE: The BOOT OPERATIONS MENU has been invoked too late for
proper operation of some activities, including Isolation Diagnostics.
You may wish to restart this controller again and press Control-B
IMMEDIATELY after seeing the start-up indicator ("-=<###>=-").

4. Execute the following commands and collect the output:

-> loadDebug
-> dqlist

5. If the commands are not found, stop the action plan here. Otherwise, move
to next step.

6. Collect the debug traces:

-> watchdogSuspend
-> isp dqprint "trace"
-> watchdogResume

7. If possible at all, collect a fresh supportdata.

Part B. Attempt Resolution

For the majority of the known instances, this issue is solved by turning the Autoload Disable switch from On to Off (Off being the default value). Check the switch in the BOOT OPERATIONS MENU of the Controller. If it is On, then this solution applies.

- Get to the BOOT OPERATIONS MENU for the controller reporting the 0F.
