Symptoms

Storage cell will fail to boot.Does not detect any disks and ILOM output will indicate the X4270M2 (storage Cell) is a X4170M2 (Compute Node).

Cause

Collect ILOM snapshot and check FRU (Field Replacable Unit) output contained in ipmi directory/collection.The  Product name indicates X4170M2

FRU Device Description : MB (LUN 0, ID 4)
Board Product         : ASSY,MOTHERBOARD,X4170/X4270,M2
Board Serial          : 0328MSL-1144BA2FU6
Board Part Number     : 511-1213-07 
Board Extra           : 02
Board Extra           : X4170/X4270_M2
Product Manufacturer  : ORACLE CORPORATION  
Product Name          : SUN FIRE X4170 M2 SERVER 
Product Part Number   : 000-0000-00
Product Serial        : 0000000000
Product Extra         : 080020FFFFFFFFFFFFFF002128E87EAC

In addition NONE of the following devices are detected.

FRU Device Description : PS0 (LUN 0, ID 63)
 Device not present (Requested sensor, data, or record not found)

FRU Device Description : PS1 (LUN 0, ID 64)
 Device not present (Requested sensor, data, or record not found)

FRU Device Description : DBP (LUN 0, ID 210)
 Device not present (Requested sensor, data, or record not found)

FRU Device Description : PDB (LUN 0, ID 211)
 Device not present (Requested sensor, data, or record not found)

FRU Device Description : PADCRD (LUN 0, ID 222)
 Device not present (Requested sensor, data, or record not found)

FRU Device Description : FB (LUN 0, ID 212)
 Device not present (Requested sensor, data, or record not found)

This problem can be misleading as it can also be caused by a failing PDB (Powed Distribution Board) ,which will cause a X4170M2 to be reported as X4270M2 .See solution to determine if this is PDB or Disk Backplane.

Solution

 Connect to the Serial MGMT console and power cycle the System.The check the displayed output.

The following can be seen.

1. Check for Error reading Reg 0x6 from MAX7133 @ 0x44, Port 4

2. Now check the I2C Probe Tests and look for the  MAX7xxx device and Adress 0x44 on port 4 .It can be seen the only match is for the Disk Backplane test

Therefore the failing device is the Disk Backplane and will require replacing.

This technique can also be used to check for other failing devices by matching the failing error address, device and port.

This event may also be seen on X4170/X4170M2 .They will correctly show their product type but will exhibit the error address 0x44

This event may also be seen on X4275 which is displayed as X4170 but also displays the 0x44 failing address.
