Solution 1456741.1 : Sun Storage 7000 Unified Storage System: Service Processor has stopped responding to requests

Applies to:

Sun ZFS Storage 7320 - Version Not Applicable to Not Applicable [Release N/A]
Oracle Exalogic Elastic Cloud X2-2 Hardware - Version All Versions and later
7000 Appliance OS (Fishworks)

Symptoms

An Exalogic or NAS 7000 Appliance may see the below alert :

SUNW-MSG-ID: AK-8001-GU, TYPE: alert, VER: 1, SEVERITY: Minor

EVENT-TIME: Wed Apr 18 05:55:05 2012

PLATFORM: i86pc, CSN: 1122334455, HOSTNAME: node01

SOURCE: svc:/appliance/kit/akd:default, REV: 1.0

EVENT-ID: 49cca6f4-3e56-c046-d441-825c88b33e2b

DESC: The service processor has stopped responding to requests.

AUTO-RESPONSE: None.

IMPACT: Features that depend on service processor functionality, including hardware inventory, LED control, and fault diagnosis, will not function correctly while the service processor is in this state.

REC-ACTION: Restart the service processor. Contact your service provider if the problem persists.

A few minute later after the given alert is generated the system might post another alert and SP resumes working:

"The service processor has resumed responding to requests."

Service processor resets itself to recover from this situation.

You will notice a sysevent as in the bundle under fm/infolog_hival.txt or by running "fmdump -l"

Cause

The Service Processor may have become unresponsive because of know software limitations - one is a memory leak issue.

Solution

As a workaround, if the Service Processor does not come back, it can be reset as mentioned below:

Login to ILOM console and reset the Service Processor to recover from this situation manually.
-> reset /SP
Login to the CLI of the Sun ZFS Storage 7000 and reste the Service Processor.
S7000 > confirm maintenance hardware select chassis-000 select sp reset
Use the BUI to reset the Service Processor.
Maintenance -> Hardware -> Show Details -> SP and click on recycle button at line saying Service Processor

If you hover the mouse pointer over the recycle button it will tell what action will be executed. A similar button in a different location on the screen is used to reboot the Appliance.

Resetting the Service Processor will not reboot the Appliance, it just resets the Service Processor.

If the problem appears again, engage Oracle Support for investigation of the issue.
