Purpose

This document discusses general resolutions for issues faced during firmware upgrades on ZFS Storage Appliance (Unified storage 7000 series).

Additionally the document also contains links and references to other documents required to troubleshoot specific issues.

Troubleshooting Steps

The Appliance Kit or ak software contains a customized OS image which also includes the firmware for hardware components like disks, SIM, SAS HBA, Logzilla, disks etc.

Currently the SP firmware and BIOS need to be upgraded separately and are not part of the Appliance Kit software. See <Document 1174698.1> to check the SP and BIOS levels.  If these are below the recommended versions please open a Service Request with Oracle Support to have them upgraded.  The SP and BIOS upgrade can be carried out remotely by an Oracle Support representative using Shared Shell or some other remote access technology to access the Service Processor (SP / ILOM).

Since the firmware upgrade is performed online we should have two paths available to the disks and all SIMs should be online. Most of the time it is seen that existing issues on the system may prevent the upgrade of the firmware and thus these need to be resolved before proceeding further.

General Recommendations:

To avoid issues during a firmware upgrade please check for the following :

• Access to ILOM, BUI/CLI interface IP (private IP)

• No resilvering is going on

• Check and resolve existing alerts and problems which may prevent update

• Previous Firmware upgrades are not in progress i.e. no pending updates

• Check the most recent product release notes for additional preconditions that should be observed for the software release to which you are upgrading.

  Check Sun Storage 7000 Unified Storage System: Firmware update Matrix 1448931.1 for firmware matrix.

Health Check:

Though a pre-install health check is performed automatically as part of the upgrade, it is always recommended to perform a manual check to identify any existing issues with the system prior to beginning the upgrade. Specifically check for the following:

• No other active problems including software or hardware

• Physical inspection of hardware for any active problems including attached JBODs

As mentioned in the pre-requisites please be sure that no hardware issues persist on the head and the attached JBODs. You also need to verify the health of the peer node in the case of a cluster.

If a problem occurs:

Define the problem and try to isolate the issue, identify at what step the firmware upgrade fails. Collect the messages and symptoms to proceed further.

Depending upon the issue faced follow the troubleshooting steps valid for your environment mentioned below.

• Failed Health Check : Please see <Document 1401522.1>

• Failed hardware : In case a hardware fault is found, please raise a service request with the latest support bundle to get the hardware diagnosed and replaced.
  See <Document 1019887.1> for details on how to collect a Support Bundle.

• Check for availability of space in the system pool. The system log messages may be helpful here. Check the BUI:

  Maintenance - LOGS - SYSTEM

On a live system check the /var/ak/logs/jobs.txt file for details about the failed upgrade, this log can be found as logs/jobs.txt in a Support Bundle.

The /var/ak/logs/debug.sys will also be useful, in a Support Bundle this file is logs/debug.sys

At this point, if you have validated that if you have followed pre-requisites and health checks and the symptoms mentioned above doesn't match in your environment and the problem still exists and further  troubleshooting is required please contact Oracle Support Services to raise a new Service Request (SR) via the My Oracle Support portal (https://support.oracle.com) or by telephoning your Oracle Global Support telephone number.
