Solution 1547566.1 : Mx-32 How to replace a Faulty Battery in a Service Processor Proxy (SPP)

Applies to:

SPARC M6-32 - Version All Versions and later
Oracle SuperCluster M6-32 Hardware - Version All Versions and later
SPARC M5-32 - Version All Versions and later
Information in this document applies to any platform.
In a full up 4 DCU M4-32 platform with a single PDomain, all four SPPs operate as a single configured unit. If an SPP fails, the SP attempts to:

■ Automatically halt the server
■ Unconfigure the failed SPP from the set
■ Configure the remaining SPPs into a new set
■ Restart the server with the reduced SPP configuration.

The battery installed on each SP/SPP. BATT,LITH,3V,125MA,1632,DISK otherwise known as CR1632

ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

FIELD ENGINEER INSTRUCTIONS

Caution – Do not turn off an SPP while it is configured into an active PDomain. Doing so will cause the associated PDomain to panic.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

The Blue 'ready to remove' LED on the face of the failed SPP should be lit. The physical domain in which the SPP was previously configured may be up or down. As long as the SPP to be replaced is properly configured out of the system it can be replaced. If it is not configured out, then the physical domain into which it is configured must be shut down and 'stopped'.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing a SPP

1. Determining if a Service Processor Proxy Module can be removed without further intervention:

a. Use one of these Oracle ILOM commands to display faulty components:

-> show faulty

-> show /System/Open_Problems

b. If there is a failed or faulted SPP, it will show up, and one should continue with step 2 below. If you see nothing then they fault condition for which the service action was filed has been cleared already, and the pending service action to replace a SPP is now suspect.

2. Review affected components status' and LED states

a. Determine to which DCU the SPP belongs by referring to the fault report displayed in Step 1. In the line that lists the name of the faulted SPP (e.g /SYS/SPPx), 'x' is the DCU number.

b. Physical inspection of the SPP, the DCU and the IOU associated with the failed SPP is optimal. If all components are off, and the Blue 'Ready to Remove' LED is lit on the suspect SPP, then one may proceed with the replacement of the failed SPP in step 3. If physical inspection is for some reason not practical, the following commands will provide further information.

c. Determin DCU and SPP status

-> show /System/DCUs

d. Determine failed DCU status.

-> show /System/DCUs/DCU_x

If the above command fails on the same DCU_x as the failed SPPx, then it is likely the SPP / DCU is powered off.

e. Review SPP fault status. The 'show /SYS/SPPx' output contains a list of Properties one can use to confirm the fault state, power on status, part and serial number information, etc. Here is an example from a faulted SPP1:

-> show /SYS/SPP1
<snip>

    Properties:
      type = SP Board Module
        ipmi_name = /SPP1
        fru_description = M5-32 SP Proxy-Pilot3
        fru_manufacturer = Celestica Holdings PTE LTD
        fru_part_number = 07045727
        fru_rev_level = 06
        fru_serial_number = 465769T+1212J2002X
        fault_state = Faulted
        clear_fault_action = (none)
        power_state = Off

f. Assuming SPP is unconfigured and ready to remove, proceed with step 3. However, if there is any doubt as to the state of the SPP and how it will affect a running domain, then the domain should be shut down by the customer sysadmins, and then 'stopped' as follows:

-> stop /HOSTx

g. Stop the affected SPP

-> stop /SYS/SPPx

3. Replace failed SPP module

a. Use an approved and tested ground strap to protect the equipment from ESD damage.

b. Remove the SPP:

Use a T25 Torx screwdriver to loosen the captive screws (1) on the extraction levers.

c. Swing the extraction levers 90 degrees out.

d. Pull the SPP out of the slot. Place it on a static-safe mat.

Replacing the SPP Battery

1. Use a grounding strap to protect the equipment from ESD damage.
2. Remove the cover from the service processor. Remove two T20 Torx screws near the front of the cover, then lift it off.
3. Use a small flat screwdriver or similar tool to carefully pry the battery out of the battery holder.
4. To insert a new 3V 125ma Lithium disk battery, press it straight down into the battery holder. The positive side of the battery faces up.
5. Install the cover.

Install a SPP

1. Use an approved and tested grounding strap to protect the equipment from ESD damage.
2. Use a T25 Torx screwdriver to loosen the captive screws on the extraction levers.
3. Swing the extraction levers out 90 degrees.
4. Insert the SPP in the slot and push it until the extraction levers touch the edge of the slot and start to swing closed.
5. Push the SPP and close the extraction levers completely to seat the module.
6. Fasten the locking screws.
7. Start the SPP:
8. Restart the PDomain.
9. Return the faulted component to Oracle.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Restart software applications per applicable administration guides to resume system operation.
