Solution 1513138.1 : 2540-M2, 2530-M2 Array Controller 7-Segment Display Reports AL 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

A visual inspection of the 25X0-M2 array shows that the 7-segment display for the controller is not reporting the tray ID. Instead the display returns a code of AL. CAM may report the controller as Removed or non-Optimal.

Changes

No Changes to the system. In some cases, this is a new install.

Cause

Controller firmware either fails to finish SODmain complete (Start of Day Complete) or fails to properly boot due to corrupt Flash Firmware File on controller.

Solution

Contact support and open a new service request for assistance.

This solution is done with the serial shell interface of the raid controller. Access to the shell, is exclusive to trained, Oracle only, engineers. Your open service request needs to be routed to the appropriate level of engineering support to perform this work.

This action plan needs to be carried out by a L2 engineer remotely or by a Field Engineer under the guidance of a L2 engineer.

The following shell commands can be used to identify problems with the flash file system:
-> ffsShow
-> ffsCrc

Issues can be identified by noticing inconsistencies in the version numbers of the ffsShow output, or looking for a NO in the Good column of the ffsCrc output.

The ffsCrc command may not provide output unless connected via the serial port of the controller. Using telnet has been seen to not produce any output.

Sample Output:

-> ffsShow

After confirming that a bad Flash file exists the firmware must be loaded to the controller displaying AL via the serial port.

Please refer to Document 2012610.1 Sun Storage 2500, 2500-M2 and 6000 Arrays: How to Load Firmware from the Controller Shell via the Serial Port for detailed instructions on how to do this.
