How to Remove and Replace VLE Server CPU Heatsink

Solution

CAP PROBLEM OVERVIEW: CPU Module and Heatsink Replacement.

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

FIELD ENGINEER INSTRUCTIONS

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

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:

0. Make sure it is possible to completely pull out the server out of its rack, if racked.
It may imply to remove some network cables or optical fibers.
Best is to write down a simple wiring diagram prior to beginning the replacement operation.
Also make sure of the LOCATION of the CPU whose heatsink is to be replaced.

1. Attach an antistatic wrist strap.

2. Shutdown of the host, make sure the host is powered off

3. Remove the power cords.

4. Unscrew the two Phillips screws from the heatsink.

5. Twist the heatsink slightly to break the grease seal, lift off the heatsink and
place it upside down on a flat surface to prevent the thermal grease from
contaminating other components.

6. Use an alcohol pad to clean the thermal grease from both the bottom of the
heatsink and the top of the CPU.

7. Whenever you remove a heatsink, always you should replace it with another
heatsink or a filler panel; otherwise, the server might overheat due to improper
airflow.

8. If you are reusing an existing cleaned heatsink, use the syringe (supplied
with the new or replacement CPU) to apply thermal grease on top of the
CPU.

9. Make sure of the orientation of the heatsink and gently place the heatink above the CPU.

10.Tighten the four screws alternately one 1/2 turn in an X pattern until fully
seated.

11. Put back in place the power cords.

OBTAIN CUSTOMER ACCEPTANCE

Confirm the appliance is in a normal state. Check both BUI access and client data access.

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

1. Boot up the server.
2. Monitor and check the messages file (if Solaris or Linux) under usual load by the server to check
CPU temperatures are normal.
