Exadata Database Machine X2-2 Hardware - Version All Versions to All Versions [Release All Releases]

Exadata Database Machine V2 - Version All Versions to All Versions [Release All Releases]
Linux x86-64

Symptoms

X2-2 & X2-8: Fan failures for non-existent fans on X4270M2 Storage Cells.

During ILOM boot, the SP runs I2C diagnostics and believes that 2 Fan Modules (FM5 & FM6) are not present which fools it into thinking its an invalid configuration and then produces a fault for non-existent F2 & F3 on FM1 & FM3.

This may result in the host server being shutdown for a fan column fault, or not be able to power it on until the fault is cleared.

Changes

None
