Symptoms
When we did a health check for a customer's Sun[TM] StorEdge 3510 FC array
we found that this array's controller amber LED was
abnormally flashing in the following order:
Green flashes --> Amber flashes --> Off --> Green flashes --> Amber flashes

And CLI checking command " sccli > show fru " reported:

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

4 FRUs found in chassis SN#003455 at ch 2 id 12
Name: FC_CHASSIS_BKPLN
Description: SE3510 FC Chassis/backplane
Part Number: 370-5535
Serial Number: 003455

It seems that system could not get following TWO FRUs statuses:

Name: FC_RAID_IOM
Description: SE3510 I/O w/SES + RAID Cont 1GB
Part Number: 370-5537

Name: BATTERY_BOARD
Description: SE3510 Hot Swap Battery Module
Part Number: 370-5545

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

Array configurations are:

Firmware: 327R
Single controller
single hosts connected
Array S/N: 000451-0327003455
Controller P/N: 370-5537-02 with S/N: 003488

The system administrator complains that I/O performance is not as
good as they expected.

According to FCO A0237-02, we ran s3khc.pl,
the tool did not find any issues from the controller.

Reseating or resetting the controller did not fix the symptoms described as above.

Resolution
The solution was to order a controller FRU 370-5537-06, and take actions to replace the original faulty one.

Check if NVRAM was saved at an earlier date. There is no way to confirm the health of NVRAM in the array's current. state.at this time

Open a tip session to access the new controller, because the new controller
does not know the original controller configurations, such as network
configurations LUN mapping informations, etc. need to restore
nvram from previously saved file to the new controller.

Set "Controller Unique identifier" to 0.
Do not input the new Controller S/N here, the "Controller Unique
identifier" points to the array chassis S/N, once the new controller
is auto reset and up again, all original configuration comes back again !

$ tip -38400 /dev/term/a
--> Select "View and edit Configuration parameters"
--> Select "Controller parameters"
--> Select "Controller Unique Identifier(Hex) - 3455"
--> change "3455" to "0"

Now, it is time to reset controller for setting to take effect.
Wait sometime until array startup completed !

At this time, check the controller LED, No amber LED flashes,
the green LED flashes periodically as expected :

Green flashes --> Off --> Green flashes --> Off

At the hosts side, recognizes the SE3510 LUNs, mount the user file system
All okay !

check the array configurations as:

$ sccli
sccli > show fru
system can get the two MISSED FRUs informations as following:
(We omited the other four FRUs which can always be detected)

...

Name: FC_RAID_IOM
Description: SE3510 I/O w/SES + RAID Cont 1GB
Part Number: 370-5537

Name: BATTERY_BOARD
Description: SE3510 Hot Swap Battery Module
Part Number: 370-5545

...

Now,SE3510FC array becomes normal completely.
