How to Remove and Replace a VLE Server Motherboard

Solution

CAP PROBLEM OVERVIEW: Replacing Motherboard

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

VLE, ZFS, Solaris and Sun X64 Training

TIME ESTIMATE: 150 minutes

TASK COMPLEXITY: 4

DELIVERY REQUIREMENT:
This replacement implies a completed shutdown and poweroff of the servers. Replacement during a maintenance window is required.

FIELD ENGINEER INSTRUCTIONS

*************************************************************

Prior to shutting down the VLE, ASR should be disabled.  VLE must be running 1.5.x code or higher.

Disable ASR using the following procedure.

Note: The system must be registered for ASR before it can be disabled.

1. Log into the server using PuTTY or similar terminal window.

2. Run the asr_sfb.sh script.  This is a root command.  Use sudo bash, or sudo prefix as indicated below.

     cd /var/opt/StatusService/scripts

     sudo ./asr_sfb.sh

3. Select the following menu items:

     Option 2) Configure ASR Settings ONLY

     Option 15) ASR disable

     Option 17) ASR query (enabled/disabled) - verify ASR is disabled

     q) Quit

 NOTE:       After maintenance activities are complete, ASRs must be re-enabled.
*************************************************************

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

Shut down system and Power down the server.

Quiesce all IO between VTSS and the VLE storage appliance and shutdown the server.

To quiesce IO between VTSS and the VLE storage appliance, vary offline all of the VL-RTDs. With
the VL-RTDs offline, no migrations will occur. If a VTV is being migrated at the time, it should be
allowed to complete. VTVs queued to be migrated will remain queued. That may result in some
repetitive error messages from VTCS (e.g. no RTDs available).

Depending on how long the VLE will be offline, customers can choose to live with the messages or they can change applicable management classes to a temporary management class that doesn't require immediate migration. When the VLE is available again, change the management class back to the original.

To shutdown the VLE server, issue the following commands after login:

PLEASE NOTE:
These instructions were written for earlier versions of VLE code and threrefore instructions that must be run with root privileges are prefaced with the 'pfexec' command.  Newer versions of code do not use 'pfexec'.  If you are running more current VLE code then instead of using 'pfexec' preface these kinds of commands with 'sudo'.

# pfexec sync
# pfexec sync
# pfexec init 5

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Positioning the Server for Maintenance

2. Removing the Server Top Cover

Caution – Removing the top cover without properly powering down the server and disconnecting the AC power cords from the power supplies will result in a chassis intrusion switch failure. This failure causes the server to be immediately powered off.
3. Remove the Motherboard

Loosen screws that secure the MB on the chassis and disconnect all cables that connect the flash riser, power supply backplane, disk drive backplane, and fan board to the MB.
Remove all memory risers.
Remove the air divider by sliding it out of the chassis.
Remove the flash riser.
Remove the four bus bar screws securing the motherboard to the power supply
backplane.
Remove all PCIe cards from the server.
Remove the power supply cover plate that secures the SAS cables.
Position the cables off to the side, using the tab on the power supply cover.
Grasp the handle on the motherboard and slide it toward the front and then out
of the chassis.
4. Install the Motherboard and replace all removed components and cables in reverse order.

5. Return the server to operation by replacing the top cover, returning to the normal rack position and reconnecting the power cords to power supplies.

6. Power On the Server

7. If the motherboard you just replaced was in a X4-4 VLE server then turn off OSA (Oracle System Assistant) using the instructions provided in MOS Doc ID 1986150.1.

OBTAIN CUSTOMER ACCEPTANCE

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

Boot up the server. Monitor and check the messages file under usual load by the server to check

CPU temperatures are normal. Use the fmadm/fmdump to clear any previous fault affecting the old mainboard. Connect to the BUI and eventually clearly any remaning faulty component (if, of course, they belong to he mainboard unit assembly).

After replacement, confirm original appliance name and serial number used for service entitlement and warranty coverage might need to be reprogrammed on the motherboard by authorized service personnel with the correct product serial number located on the chassis EZ label.

********************************************************************

Enable ASR using the following procedure.

1. Log into the server using PuTTY or similar terminal window.

2. Run the asr_sfb.sh script.  This is a root command.  Use sudo bash, or sudo prefix as indicated below.

     cd /var/opt/StatusService/scripts

     sudo ./asr_sfb.sh

3. Select the following menu items:

     Option 2) Configure ASR Settings ONLY

     Option 16) ASR enable

     Option 17) ASR query (enabled/disabled) - verify ASR is enabled

     q) Quit
