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.

DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED?: M8-8 / M7-8 / M7-16 Product training

TASK COMPLEXITY: 2

TIME ESTIMATE: 60 minutes

HOT replacement

REMOVAL/REPLACEMENT INSTRUCTIONS:

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

The Physical Domain to which the CMIOU, holding the faulty eUSB Disk, is assigned, must be shut down.

WHAT ACTIONS ARE REQUIRED?:

Caution

To prevent overheating, fill unused CMIOU slots with CMIOU filler panels
Remove a faulty CMIOU only when a replacement CMIOU is available. Install the new CMIOU as quickly as possible, within 10 minutes, if possible.
You must prepare a CMIOU before removing it from the server. Complete the steps 1 through 3 before you unseat or remove a CMIOU

1. To determine which CMIOU is holding the faulty eUSB disk, use one of these Oracle ILOM commands to display faulty components and determine which CMIOU needs to be prepared for service:

     -> show faulty
     -> show /System/Open_Problems
     faultmgmtsp> fmadm faulty

2. Locate the affected CMIOU by its amber Service Required LED

3. Prepare the CMIOU with the faulty eUSB disk for removal. Check M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) , "Preparing a CMIOU for Removal" for details

Determine whether any of the Logical domain in the Physical domain is using VersaBoot (iSCSI over IPoIB) for booting. if so, refer to SPARC M7 Servers : VersaBoot (iSCSI over IPoIB) - CMIOU/eUSB replacement considerations (Doc ID 2107700.1)

4. Remove the CMIOU with the faulty eUSB disk from the chassis. Check M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) , "Removing a CMIOU" for details

5. Remove the faulty eUSB disk.

Remove the green T-10 screw that secures the eUSB disk to the CMIOU
Carefully lift the eUSB disk out of the CMIOU
If required, set the eUSB disk aside for installation in the new CMIOU.
- When you are replacing a CMIOU that is the only CMIOU in a logical domain guest that uses iSCSI over IPoIB (versaboot) for booting, and the eUSB disk in that CMIOU is the only disk in the boot pool, you must install the eUSB disk you remove in the new CMIOU.

6. Install the new eUSB disk.

Position the new eUSB disk in the CMIOU
Ensure proper pin engagement with connectors before pressing the eUSB disk in place
Tighten the green screw to secure the eUSB disk to the CMIOU

7. Install the CMIOU back into the server. Check M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) , "Installing a CMIOU" for details

8. Return the faulted component to Oracle.

Caution - The removed eUSB disk must be properly repackaged to prevent damage during return transportation to Oracle. The eUSB disk should be repackaged in identical fashion as the delivered FRU. See the Service Manual for details about proper repackaging.

If the replacement component included safety covers on the connectors, install the covers on the component that you are replacing.
In the shipping container that contained the replacement component:
1. Using the same material used to pack the replacement component, position the component so that it is not free to move.
2. Add any required paperwork or other documentation in the container.
3. Except when packing CMIOUs, include any tools that were loaned to you by Oracle. Do not place tools inside a container that is being used to return a CMIOU.
Close the shipping container and seal it with the packaging tape supplied by Oracle.
Apply the shipping label to the shipping container.
Notify Oracle or an authorized shipper that the carton container is ready for pickup.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE NEEDED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Verify that there is no faulty components

-> show faulty
-> show /System/Open_Problems
faultmgmtsp> fmadm faulty

Perform one of the following tasks based on your verification results

If the previous steps did not clear the fault, refer to doc 1309092.1 for information about the tools and methods you can use to diagnose and clear component faults.
If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required

If required, change the values for the /HOSTx/diag default_level and hw_change_level before starting the host.

-> set /HOST/diag/ default_level=max
-> set /HOST/diag/ hw_change_level=max

Restart the PDomain you stopped in M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) , "Preparing a CMIOU for Removal" , step 3.5, and monitor/capture console HOST console output (use two windows):

-> start /Servers/PDomains/PDomain_z/HOST/console
-> start /Servers/PDomains/PDomain_z/HOST

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

After all PDomains have restarted, repeat the steps to verify that there is no faulty components, to ensure starting the PDomains has not triggered new faults.

If a ZFS fault is reported against the eUSB disk from the CMIOU being replaced, make sure the label on the disk is correct; format/label as needed.

See SPARC M8 and SPARC M7 Series Servers : ZFS fault on eUSB disk after CMIOU replacement (Doc ID 2184100.1).

Return the /HOSTx/diag default_level and hw_change_level to their original value.
