14 Troubleshooting Hardware Faults

In rare cases, faults associated with uncorrectable CPU errors are not diagnosable or displayed in the controller. These faults will be preserved by and observable in Oracle Integrated Lights Out Manager (ILOM), located in the service processor (SP). Connect to Oracle ILOM on the server platform to diagnose hardware faults that do not appear in the BUI.

Caution:

Failure to configure Oracle ILOM connectivity might lead to longer than necessary hardware fault diagnosis and resolution times.

For more detailed information about Oracle ILOM, see Using Oracle ILOM to Diagnose Hardware Faults in Oracle ZFS Storage Appliance Customer Service Manual, Release OS8.8.x. Also see the Oracle ILOM documentation located in the documentation library for this software release at http://docs.oracle.com/en/storage/index.html.

Connecting to Oracle ILOM

After configuring the system and performing initial configuration, it is recommended that you retain a connection to Oracle Integrated Lights Out Manager (ILOM), located in the controller service processor (SP), for troubleshooting hardware problems that do not otherwise appear in the appliance software.

The controller Oracle ILOM provides options for (i) network and (ii) serial port connectivity. Network connection is the preferred choice because the Oracle ILOM serial port does not always allow adequate means of platform data collection.

1. Perform one of the following SP connections:

   • For a network SP connection (recommended), attach an Ethernet cable from the NET MGT port on the rear panel of the controller to your Ethernet switch.

   • For a serial SP connection, attach a serial cable from the SER MGT port on the rear panel of the controller to the serial port on the administrative client. Use a DB9 to RJ45 adapter if necessary.

2. For clustered controllers, repeat for the second controller.
