Information in this document applies to any platform.

Purpose

This document provides the set of commands required to collect diagnostic information required for disk failures on the Exalogic nodes and for some other hardware issues.

Troubleshooting Steps

When diagnosing an hardware (HW) issue, you will likely be asked by the Service Request owner to provide data to investigate.

Here is a first set of commands, tools that can be ran to first troubleshoot or to be sent to the support.

Disk issues related to a Compute Node: (also called Cell Node), these commands should help to get the current status of the hardware RAID mirror :

# /opt/MegaRAID/MegaCli/MegaCli64 -Ldinfo -lAll -aAll

# /opt/MegaRAID/MegaCli/MegaCli64 -PdList -aAll

Disk issues related to the ZFS appliance: collecting a supportbundle is the best way to proceed :

<Document: 1019887.1> : Sun Storage 7000 Unified Storage System: How to collect a supportbundle using the BUI or CLI

Other suspected HW issues :

For the suspected hardware issues which are not related to the disks, running a snapshot from the affected node is a good first step.

<Document: 1020204.1> : Collecting snapshot on ILOM 3.x and later platforms

NB : In some cases, it could even been requested for disk issues.

In rare cases (mostly for the Preventive Maintenance SR), you may be asked for an Exachk, which is a health-check tool designed to audit the different configuration settings inside the whole Exalogic system (at HW and mainly SW point of view).

The procedure to use this tool can be found on <Document: 1449226.1> : Exachk Health-Check Tool for Exalogic.
