CAP PROBLEM OVERVIEW: Replace a Drive Backplane

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Sun Netra Server X3-2 Server Training.

Note: The server ships with one of two drive configurations. The server can have six drives and a DVD drive, or eight drives and no internal DVD drive. For each configuration, the drive backplane is unique. The drive backplanes are distinguished by the inclusion or lack of an SATA connector, which supports the DVD drive.

TIME ESTIMATE: 45 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. Then power off the server and remove the AC power cords from the system.

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

Power off the server and disconnect the power cords from the power supplies.
Extend the server to the maintenance position in the rack.
Attach an anti-static wrist strap.
Remove the top cover.
Remove the front air filter
Remove all of the disk drives, mark the drives so that they will be reinstalled in the correct slots.
Remove all of the fan modules.
Remove the fan tray.
Raise the Drive Tray to the Service Position.
1. Disconnect the cables attached to the drive backplane, and the cable attached to the USB board.
2. Fully loosen the four screws securing the drive cage to the chassis.

2. Remove the five screws from the drive backplane.

3. Lift the drive backplane off of the alignment pins and out of the chassis.

4. Set the drive backplane aside.

5. Position the drive backplane to where it will install into the chassis.

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.

6. Install and tighten the five screws.

7. Install the remaining parts in the following order:

Secure the Drive Tray.
1. Fully tighten the four screws securing the drive cage to the chassis.
2. Connect the cables attached to the drive backplane, and the cable attached to the USB board.
Install the fan tray.
Install all of the fan modules.
Install all the drives in the correct original slot locations.
Install the front air filter.
Replace the top cover
Remove any anti-static measures that were used.
Return the server to it's normal operating position within the rack.
Re-install the AC power cords and any data cables that were removed.
Power on server. Verify that the Power/OK indicator led lights steady on.

8. Set the system serial number/fruid data if needed.

Disk Backplane 0 is the primary psnc container in this server so when it is replaced you will normally need to fix the serial number information.
login to the ILOM as root and then enter the restricted shell to check the psnc values. Follow the example below to enter restricted shell and use the showpsnc command
1. -> set SESSION mode=restricted

  [(restricted_shell) nx4270m3-sp:~]$exit
When Disk Backplane 0 is replaced the Primary psnc container will likely not match the Backup entries. If it does not you must enter escalation or service mode to fix it (if all three entries match this step is done)
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).
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 see in step b above as well.
The TSC will provide an escalation password that is made up of 30 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.
1. -> 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 = *****
set the check_physical_presence to false and then exit from the ILOM so that you can login as the newly created user.
1. -> set /SP check_physical_presence=false
  Set 'check_physical_presence' to 'false'
  -> show /SP check_physical_presence
  /SP
  Properties:
  check_physical_presence = false
  
  -> exit
Login using the escuser login and enter escalation mode using the password that was provided by the TSC
1. nx4270m3-sp login: escuser
  Password: ********

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 psnc backup use the copypsnc command to write the good data from the backup to the primary container on the fan board. The following example shows copying from backup1 to the primary but you could also copy from backup2 if needed.
1. [(escalation_mode) nx4270m3-sp:~]# showpsnc
  Primary: fruid:///SYS/DBP
  Backup 1: fruid:///SYS/MB
  Backup 2: fruid:///SYS/PDB

  [(escalation_mode) nx4270m3-sp:~]# exit
At this point if all of the psnc containers match and have the correct serial number data this step is done. If more than one of the psnc 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 Backup1 Backup2" to copy backup1 to backup2) After confirming all psnc data is correct reset the ILOM to confirm that the psnc data persists through a reboot and remove the escalation user if needed.
1. -> 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 psnc data***
  
  -> set SESSION mode=restricted
