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 the Oracle ILOM, located
in the service processor. 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 Cabling Guide. Also see the Oracle ILOM
documentation located in the documentation library for this software release at http://docs.
oracle.com/en/storage/.
Connecting to Oracle ILOM
After configuring the system and performing initial configuration, it is recommended that you
retain a connection to Oracle ILOM, located in the controller SP, for troubleshooting hardware
problems that do not otherwise appear in the appliance software.
The server Oracle ILOM provides options for (i) network and (ii) serial port connectivity.
Network connection is the preferred choice, as 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.
