Symptoms

Once Bios and Firmware have been upgraded, the 7120 will report and capture these alerts from the Aura 1.0.   For example, one week before an ESM reaches its threshold, Oracle ILOM issues this warning message:

     "/SYS/MB/RISER1/PCI4/F20CARD ESM is approaching its lifespan.
               Please schedule a replacement as soon as possible."

When an ESM reaches its threshold, Oracle ILOM issues this critical event message:

     "/SYS/MB/RISER1/PCI4/F20CARD ESM has exceeded its lifespan.
              Please schedule a replacement as soon as possible."

Impact

Because the Aura 1.0 card onboard Energy Storage Module (ESM) has a limited lifespan, Oracle provides options that monitor how long an ESM has been installed, and notifies you when to replace the ESM. The 7120 uses Oracle ILOM to monitor the F20 card. Oracle ILOM will track the ESM lifespan and notify you when to replace the ESM.

It has been shown that once the ESM on the card looses it charge there is an increased probability of data loss or corruption.

The ESM for the 7120 should be replaced every three years to ensure adequate charge to offload data stored on the card in case of a power failure.

In order to properly track and report the 3 year lifespan of the ESM an upgrade to FW code to a version higher than 2010.q3.4.0, and ensure Service processor BIOS 3.0.14.11+BIOS 08060108 or higher.

Changes

Note this issue only affects 1 and 2 TB 7120 configurations as listed below;

  TA7120-24TB Sun Storage 7120 system with twelve 1 TB 7200 rpm 3.5-inch SAS HDDs
  TA7120-12TB Sun Storage 7120 system with twelve 1 TB 7200 rpm 3.5-inch SAS HDDs

Other configs are not affected.

Oracle supports two versions of ILOM software on the 7120.

  3.0.9.27+BIOS 08040110
  3.0.14.11+BIOS 08060108

3.0.9.27 ILOM software sets the ESM timer value at 2 years. ILOM code needs to be upgraded to 3.0.14.11 to set the correct 3 year timer value.

The BIOS and ILOM upgrades need to be done by an Oracle employee and cannot be done by the customer.  The AK software will not capture either of these alarms until it has been upgraded to 2010.q3.4.0 or higher.

Resolution

ILOM code needs to be upgraded to 3.0.14.11 to set the correct 3 year timer value. The AK software will not capture either of these alarms until it has been upgraded to 2010.q3.4.0 (or higher). The BIOS and ILOM upgrades need to be done by an Oracle employee and cannot be done by the customer.

NOTE: BIOS Upgrade should only be done with the help of the TSC, and a call should be opened before attempting any BIOS upgrade.
