Symptoms

After an Exadata Cell disk replacement, the drive fault yellow LED remains on.

Changes

The drive has just been replaced

Cause

The LED is lit by the ILOM in response to an alert from the LSI MegaRAID controller. However, if the ILOM is suffering from a memory leak, it does not get the message to turn the LED off.

Solution

Workaround:
Restart the ILOM management process clears up the issue temporarily:

In order to restart the management process, execute the following command on each storage node.
cellcli> alter cell restart bmc
This will restart the ILOM management processor and reset the ILOM memory. Since other functions of the storage node will not be affected, this ILOM management process restart may be performed without downtime.

Solution:
1. Upgrade the storage cells to 11.2.2.3.2, using Patch 12577723, "Exadata Storage Server software 11.2.2.3.2" This process will also upgrade the Storage Server ILOM software to the needed 3.0.14 ILOM firmware version.

2. The same process includes instructions to use the Minimal Pack for Database Host in README section 6. This Minimal Pack will also upgrade the Compute Node ILOM software to the needed 3.0.14 ILOM firmware version.
