Solution 1561060.1 : Sun Storage 6140 Array: Controller Redundancy Mode Changes to SIMPLEX After Upgrading to 7.xx Firmware Using Upgrade Utility

Applies to:

Sun Storage 6140 Array - Version Not Applicable to Not Applicable [Release N/A]
Information in this document applies to any platform.

Symptoms

After a firmware upgrade from 6.x to 7.x, using the Crystal Upgrade Utility, controller B will be in a failed state.

7-segment display on controller B will show "88".

Common Array Manager generates following alarms.

Cause

During a firmware upgrade from 6.x to 7.x using the Crystal Upgrade Utility, it is possible to wrongly choose the SIMPLEX NVSRAM file (N399X710843-902.dlp) for 6140.

Even though single controller configurations (also called simplex configurations) are not supported in 6140, the SIMPLEX NVSRAM file bundled with the upgrade utility can still be chosen in error.

The upgrade guide clearly warns as below.

Note – An additional NVSRAM file N399X-710843-902.dlp is included for single
controller configurations. However, this configuration and file are not supported.

Solution

1. Do not select the SIMPLEX NVSRAM file during upgrade from 6.x to 7.x.

2. If you wrongly choose the SIMPLEX NVSRAM, then the redundancy mode need to be changed to DUPLEX.

Please raise a service request with Oracle Support to assist you in resolving the issue.

Internal

Make sure

1.Customer has upgraded from 6.x to 7.x using the Upgrade Utility
2.Check in the storage profile the NVSRAM version is "N399X-710843-902" and the Redundancy mode is "SIMPLEX". "xx-xx-902" indicates SIMPLEX nvsram.
3.Cntr-B in FAILED state.
4.7-Segment DISPLAY shows "88"

Resolution

-------------

Using "service" command change the redundancy mode from SIMPLEX to DUPLEX .

Note : Like in 25xx there is no service advisor procedure to convert SIMPLEX to DUPLEX for 6140 array.

Use following service command to change the mode

service -d <array-name> -c set -q redundancy -t duplex

After you execute the service command make sure the redundancy mode changed to DUPLEX and Cntr-B is Optimal.

Once you execute this command Redundancy Mode will change to DUPLEX. But the NVSRAM version will still show as "N399X-710843-902".

Install latest CAM and upgrade baseline in order to install the right NVSRAM.

bash-3.00# ./service -d st6140-sin06-g -c set -q redundancy -t duplex
Executing the set command on st6140-sin06-g
Completion Status: Success
