3.11 Exadata Storage Server LED Indicator Descriptions

The indicator LEDs on Oracle Exadata storage servers help you to verify the system status and identify components that require servicing.

For information about the various indicator LEDs on Oracle Exadata storage servers, see the section on Troubleshooting Using the Server Front and Back Panel Status Indicators in the server service manual for your system.

See Related Documentation for a list of the server service manuals.

Additionally, the Do Not Service LED is included only on Oracle Exadata X7-2 and later storage servers.

On Oracle Exadata storage servers, the Do Not Service LED has the following states:

• Do Not Service LED is white/on: Indicates that the storage server is required to remain online to preserve data availability. Do not restart or power off the storage server. Otherwise, data availability may be compromised.

  Typically, the Do Not Service LED lights in response to an issue with a partner storage server. However, the Do Not Service LED also lights in the following situations:

  • During an Oracle ASM cluster rolling upgrade, the Do Not Service LED lights simultaneously on all participating storage servers. Furthermore, on affected grid disks, the asmDeactivationOutcome attribute contains the value: Cannot deactivate because ASM is in rolling upgrade mode.

  • When a database server containing a voting disk goes down, the Do Not Service LED lights simultaneously on all storage servers, which warns against shutting down any storage servers to preserve quorum in the cluster.

• Do Not Service LED is off: The storage server can be safely powered off for servicing.
