Sun Storage 7000 Unified Storage System: Thermal Events and Ongoing Fan issues on 7410/7110 storage arrays (Doc ID 1386616.1)

Last updated on FEBRUARY 04, 2013

Applies to:

Sun Storage 7110 Unified Storage System - Version Not Applicable to Not Applicable [Release N/A]
Sun Storage 7410 Unified Storage System - Version Not Applicable to Not Applicable [Release N/A]
7000 Appliance OS (Fishworks)

Symptoms

Thermal shutdown events reported on Sun Storage 7410 Unified Storage and Sun Storage 7110 Unified Storage System arrays.

Previous Array history of ongoing Fan issues being reported (usually via ASR) and Service Processor resets attempted to resolve the situation, but issues persist. In extreme situation the Sun Storage 7000 Unified Storage System experiences a Thermal Shutdown event.
 
High temperature alerts logged in storage controller iLOM or ipmp logs via SupportBundle/BUI

[logmgr: ID = 7401 : Wed Dec 7 07:02:21 2011 : IPMI : Log : critical : ID = 3a4 : 12/07/2011 : 07:02:21 : Temperature : sys.t_amb : Upper Critical going high : reading 44 > threshold 40 degrees C]


Reported incidents of  Sun Storage 7000 Unified Storage System controller automatically shutting down due to over temperature warning to prevent system overheating can be confirmed with collecting following data:

  1. Fan LED status currently or before array shut down. Suspect Amber LED's
  2. Current ambient data center temperature in local environment is within an acceptable range
  3. iLOM snapshot if possible
  4. Any recent SupportBundle data if available
  5. If allowed to cool down the system, restart the Service Processor and the System using the console and monitor the system coming up

If you see multiple External sensors fan errors at FM 0 + FM 1 + FM 2 at same time then this can be BUG 6925325

iLOM prompt:   reset /SP/
CLI> Maintenance - hardware - select - chassis-000 - select - SP - reset

Changes

Previous SR's  dealt with Fan issues and a reported Service Processor Memory leak situation that was resolved with an SP reset.

Customer will need to confirm the current LED status of the FANS on this unit and confirm if the actual environmental temperature is indeed in an acceptable range within their Data Center.

An iLOM snapshot would also be useful at this time. I have included a link to the iLOM Service Processor sunservice data collection script, collectDebugInfo.sh

To find the SP-IP adress go to Web Gui:
Maintenance --> Hardware-> select the Head-> go to "Show Details" -> go to "SP"
