Solution

CAP PROBLEM OVERVIEW:  Disk Backplane (DBP) replacement

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Netra Server X5-2 Training.

TIME ESTIMATE: 30 minutes

TASK COMPLEXITY: 3-FRU

FIELD ENGINEER INSTRUCTIONS

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

If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS.  A data backup is not a prerequisite but is a wise precaution.

Removing the disk backplane is a cold-service operation. You must power off the server and and remove the AC power cords from the system before you remove the disk backplane.

1. Consider your first step.

•  If you have not prepared for service, do so now. See “Preparing for Service”.
•  If you are removing the motherboard as part of another component's removal or installation procedure, go to Step 2.

2. Review this information and complete these prerequisites in this order.

• Remove the Filter on page 89
• Remove Disk Drive on page 97
  
  • Remove all of the disks
• Remove the DVD drive on page 103 (if necesary)
• Rotate the Drive Cage to the Service Position on page 81
• Remove the Drive Backplane page 161

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Log into the ILOM check the fruid container values and sync them if needed.

1. To avoid mismatched fruid values causing a failure after a disk backplane replacement the fruid data should be confirmed to have matching data in at least the Backup 1 (MB) and Backup2 (PDB) containers so that the Disk Backplane will have it's container updated automatically after replacement. Go into restricted mode and use the showpsnc command to check this.  
   -> set SESSION mode=restricted

2. The above example shows a system with all three containers properly in sync. If the output from the system does not show all of the containers with matching values then you should reset the SP and then re-check the values again. An ILOM reset will attempt to auto-populate the matching values if one container is out of sync.  
   -> reset /SP
   Are you sure you want to reset /SP (y/n)? y
   Performing reset on /SP
    
3. After an ILOM reset if the Backup1 and Backup2 containers match then proceed with the following steps to replace the disk backplane. If these two containers do not match then DO NOT proceed with the replacement yet.
4. If the containers do not match you will need to use the copypsnc command from service or escalation mode to copy the data from the good container so that the Backup1 and Backup2 containers match (Primary is the DBP). If you are unfamiliar with this process and require assistance please reference the steps for using copypsnc to fix the serial number detailed in the "How to update product serial number on systems which implement TLI functionality (Doc ID 1280913.1)" and contact the TSC if needed. How to access service mode and escalation mode on ILOM 3.x and later platforms (Doc ID 1019946.1)
5. After the fruid data in the Backup1 and Backup2 containers have been confirmed to match proceed with the following steps.

2. Prepare the server for service.

1. Power off the server and disconnect the power cords from the power supplies.
2. Remove  the server from the rack.
   1. 4-Post, 19-inch Hardmount Rack Instructions
      1. Support the weight of the server for removal.
      2. Loosen the center captive screw on the left and right rear support brackets.
      3. Remove the two screws securing each hardmount bracket at the front of the rack.
      4. Lift the server from the rack and set it aside on an antistatic mat.
   2. 2-Post, 19-inch Hardmount Rack
      1. Support the weight of the server for removal.
      2. Remove the two screws that secure each rear plate to the back of the post.
      3. Loosen the two screws that secure each rear plate to the eyelets of the side bracket.
      4. Slide each rear plate out of the eyelets and set them aside.
      5. Remove the two screws from each side bracket at the front of the posts.
      6. Lift the server from the rack and set it aside on an antistatic mat.
3. Attach an anti-static wrist strap.

3. Remove the Front Air Filter and the server Top Cover.

1. On the front air filter pinch the right and left release levers inwards, pivot the air filter forward and lift it out and away from the chassis.
   
2. Fully loosen the two captive screws at the rear of the top cover.
3. Slide the top cover backward about .50 inch (13mm), lift top cover straight up and off from chassis.    
   Note: If the top cover will not slide back, you may have to loosen or remove the top two screws on both the left and right rack support backet.  These top screws cause the support backet to press against the top cover.
     
   

4. Remove all of the SAS, NVMe and the DVD disks from the disk cage, rotate the Disk Device Cage

1. For each SAS and NVMe disk:
   
   1. Press the release button and pivot the release lever open to the right.
   2. Grasp the release lever and pull the drive out of the chassis. 
      
   3. Set disk aside,, either mark each disk or place in an order to assure each disk will be reinstalled in the correct disk slot.
2. Remove the DVD drive:
   1. Grasp the tab under the right side of the DVD drive and pull the tab out.
   2. Continue to pull the tab, so that the DVD drive slides out of the chassis.
   3. Set DVD drive aside
3. Disconnect the cables attached to the disk backplane and the cable attached to the USB board.
4. Fully loosen the four captive screws securing the drive cage to the chassis (use a No. 2 Phillips screwdriver).
5. Rotate the drive cage to the vertical position.

5. Remove the Disk Backplane (DBP):

1. Loosen the five screws from the drive backplane.
2. Lift the drive backplane off of the alignment pins and out of the chassis.
3. Set the drive backplane aside.

6. Install the replacement Disk Backplane:

1. Position the drive backplane to where it will install into the chassis.
2. The drive backplane aligns with the drive connectors down. The two alignment holes are on the left and the single alignment hole is on the right.
3. Tighten the five screws.

7. Secure the Disk Device cage, reinstall the DVD drive and all of the SAS and NVMe disks.

1. Route the USB cable into the cable channel in the PSU air duct.
2. Lower the drive cage to the horizontal position.  Confirm that the alignment holes at the rear of the drive cage are over the alignment pins underneath.
3. Tighten the four screws securing the drive cage to the chassis.
4. Connect the cables to the drive backplane and the cable attached to the USB board.  Plug each cable into its connector until you hear an audible click.
5. Reinstall the DVD drive:
   1. Extend the tab out from the underside of the DVD drive.
   2. Align the DVD drive to the location where it installs into the chassis.  The DVD drive is oriented with the tab at the right front.
      
   3. Slide the DVD drive into the chassis.
   4. Press on the right side of the DVD drive to firmly seat it into the slot.
   5. Push the tab in under the DVD drive.
6. For each SAS and NVMe disk:
   1. Push the release button of the drive.  The release lever pops out.
   2. Align the drive with the slot where it installs into the chassis.  The connector is at the rear of the drive and the release button is on the left.
   3. Press on the drive to slide the drive into the chassis until the release lever moves slightly inward.
   4. Press the release lever fully closed with a click, securing the drive into the chassis.

8. Reinstall the front air filter and top cover:

1. Reinstall the air filter
   1. Set the bottom edge of the filter into the lip at the front of the chassis.  The left and right release levers are facing forward.
      
   2. Pivot the filter to vertical.  The release levers snap the filter into place.
2. Install the top cover
   1. Position the top cover on the chassis, with the front edge of the top cover 0.5 in. (13 mm) rearward of the front edge of the chassis.
   2. Slide the top cover forward into place.
   3. Secure the top cover with the two captive screws at the rear.
3. Reinstall or tighten the side support bracket screws.
   

9. Return the Server to operation.

1. Remove any anti-static measures that were used.
2. Return the server to it's normal operating position within the rack.
3. Re-install the power cords and any data cables that were removed.
4. Power on server. Verify that the Power/OK indicator led lights steady on.

10. Verify the system serial number/fruid data if needed.

1. The Disk Backplane is the primary fruid container in this server so when it is replaced you will normally need to fix the serial number information.
2. Login to the ILOM as root and then enter the restricted shell to check the fruid values. Follow the example at the beginning of these instructions to enter restricted shell and use the showpsnc command.
3. If it does not you must enter escalation or service mode to fix it (if all three entries match this step is done).
4. Contact the TSC to request an escalation password (service mode will work also if just the copypsnc command ends up needing to be used, if the setpsnc command is needed escalation mode is required. setpsnc is not covered in this procedure).
5. Provide your TSC contact the output from the following ILOM commands- "version", "show /SYS product_serial_number", and "show /SP/clock". If the product_serial_number information does not give good output then provide the showpsnc output that was seen in step b above as well.
6. The TSC will provide an escalation password that is made up of 32 short words. Follow the example below to create a new user with the 'Service' role assigned. The Service role is required to access service or escalation modes. In the following example we will create a user named 'escuser' with the service role.
   -> cd /SP/users
   /SP/users
   -> create escuser
   Creating user...
   Enter new password: ********
   Enter new password again: ********
   Created /SP/users/escuser
   -> set escuser role=aucros
   Set 'role' to 'aucros'
   -> show escuser
   /SP/users/escuser
   Targets:
   ssh
   Properties:
   role = aucros
   password = *****
7. Set the check_physical_presence to false and then exit from the ILOM so that you can login as the newly created user.
   -> set /SP check_physical_presence=false
   Set 'check_physical_presence' to 'false'
   -> show /SP check_physical_presence
   /SP
   Properties:
   check_physical_presence = false
   
   -> exit
8. Login using the escuser login and enter escalation mode using the password that was provided by the TSC.
   ORACLESP-NX5-2 login: escuser

9. Use the showpsnc command to confirm the current container values. Confirm that one of the backup containers has a serial number (the value on the PSN line) that matches the system serial number. The system serial number can be checked by comparing to the serial number RFID tag on the front left hand side of the server. After confirming that there is a valid fruid backup use the copypsnc command to write the good data from the primary to the backup1 container on the MB. The following example shows copying from primary to the backup1 but you could also copy from backup2 if needed.
   
   [(restricted_shell) ORACLESP-NX5-2:~]# showpsnc
   Primary: fruid:///SYS/DBP
   Backup 1: fruid:///SYS/MB
   Backup 2: fruid:///SYS/PDB
   
   Element           | Primary           | Backup1           | Backup2

   Product Name        NETRA SERVER X5-2   NETRA SERVER X5-2   NETRA SERVER X5-2 
   
   [(escalation_mode) ORACLESP-NX5-2:~]# copypsnc Backup1 Primary
   [(escalation_mode) ORACLESP-NX5-2:~]# showpsnc
   Primary: fruid:///SYS/DBP
   Backup 1: fruid:///SYS/MB
   Backup 2: fruid:///SYS/PDB

   Product Name        NETRA SERVER X5-2   NETRA SERVER X5-2   NETRA SERVER X5-2 
   [(escalation_mode) ORACLESP-NX5-2:~]# exit
   
   
10. At this point if all of the fruid containers match and have the correct serial number data this step is done. If more than one of the fruid containers had non-valid entries then the copypsnc command should be used to copy over the valid data to the other container that is not valid. (ie. "copypsnc Primary Backup2" to copy primary to backup2) After confirming all fruid data is correct reset the ILOM to confirm that the fruid data persists through a reboot and remove the escalation user if needed.
    
    -> reset /SP
    Are you sure you want to reset /SP (y/n)? y
    Performing reset on /SP
    ..........
    
    ***login as the root user again and check the fruid data***
    
    -> set SESSION mode=restricted
