FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS

PROBLEM OVERVIEW: An Exadata X7-2 Compute Node Server has a faulted internal cable that needs replacement

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

IMPORTANT NOTE TO TSC ENGINEER: CUT & PASTE the “CUSTOMER ACTIVITY” sections of the Pre-Replacement and Post-Replacement steps into a SR Note and ensure the customer is aware to do these steps prior to the scheduled field engineer activity, and during and after the replacement activity.

CUSTOMER ACTIVITY:

Shutdown of the database node is required prior to the part replacement:

If running Linux or Solaris native - follow Steps 1 to 9 of MOS Note:
How to shutdown the Exadata database nodes and storage cells in a rolling fashion so certain hardware tasks can be performed. (Doc ID 1539451.1)

If running OVM then follow MOS Note:
How to Shutdown and Startup Exadata database nodes running OVM (Doc ID 2367609.1)

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

Prepare the Server for Service

The customer should have already prepared the server and powered it off. If not, provide them the instructions in the previous section.

1. Extend the server to the maintenance position
2. Disconnect the power cords from the power supplies
3. Attach an anti-static wrist strap to your wrist and to a metal area on the chassis or the rack.
4. Remove the server top cover. Use a Torx T10 screwdriver to unlock the release button latch.

Caution - These procedures require that you handle components that are sensitive to electrostatic discharge. This sensitivity can cause the components to fail. To avoid damage, ensure that you follow anti-static practices.

The following cables are included in the Oracle Server X7-2 Cable Kit - 7344566 [F] Cable Kit:

7315511 8-Pin DC Power Cable, 553mm
7329638 3-Pin Temperature Sensor Cable, 400mm
7329640 11-Pin Front Interface Module Cable, 635mm
7336380 SFF-8611 to 90° SFF-8611 M.2 SATA Cable, 130mm
7344626 34-Pin Disk Backplane Data Cable, 550mm

Replacing the Disk Backplane DC Power Cable

7315511 8-Pin DC Power Cable

Removal:
1. Disconnect the disk backplane power cable from the motherboard by pressing in on the connector latch and then pulling out the cable connector.

2. Disconnect the disk backplane power cable from the disk backplane by pressing in on the connector latch and then pulling out the cable connector.

3. Lift up and remove the cable from the chassis.

Installation:
1. Install the DC power cable into the chassis, routing it flat through the channel between the fan modules and the chassis side wall.

2. Insert the cable into the disk backplane connector until it latches.

3. Insert the cable into the motherboard connector until it latches.

Replacing the Temperature Sensor Cable

7329638 3-Pin Temperature Sensor Cable - use the replacement procedure detailed in Doc ID 2359356.1.

Replacing the Front Indicator Module Cable

7329640 11-Pin Front Interface Module Cable - use the replacement procedure detailed in Doc ID 2359285.1.

Replacing the M2.SATA Data Cable

7336380 SFF-8611 to 90° SFF-8611 M.2 SATA Cable - this cable is not used in Exadata X7-2 Compute Node Server configurations

Replacing the Disk Backplane Data Cable

7344626 34-Pin Disk Backplane Data Cable

Removal:
1. Unlatch the disk backplane data cable from the motherboard connector slot.

Note - You might need to disconnect the SAS cable connections from the Oracle Storage 12 Gb SAS PCIe RAID HBA, Internal card in PCIe slot 4 to access the disk backplane data cable motherboard connection. To ease removal of the cable, slightly lift the SAS cable bundles from the cable trough along the left side of the chassis.

2. Unlatch the disk backplane data cable from the disk backplane connector slot.

3. Carefully lift up and remove the cable from along the left chassis wall and out of the chassis.

Installation:
1. Carefully install and route the cable along the left chassis wall, similar to how the previous cable was installed. Take care not to snag the cable on the DIMM connector levers.

2. Latch the disk backplane data cable to the disk backplane connector slot. Press to ensure the latch locks are closed.

3. Latch the disk backplane data cable to the motherboard connector slot. Press to ensure the latch locks are closed.

Note - Re-lay the SAS cable bundles on top of the disk backplane data cable and other cables carefully so they do not snag on the DIMM connector levers and lay fully into the chassis and will not interfere with the chassis lid closing.

Return the Server to Operation

1. Install the server top cover. Use a Torx T10 screwdriver to lock the release button latch.
2. Reconnect the power cords to the server power supply and connect any other cables to their original locations.
3. Return the server to the normal rack position.
4. Once the power cords have been re-attached and the ILOM has booted you will see a slow blink on the green LED for the server. Power on the server by pressing the power button on the front of the unit.
5. Connect to the server console via the ILOM and monitor the boot.
By default the ILOM serial console displays the primary console output.
In the event of unexpected boot behavior, it is advisable to connect to both ILOM serial and ILOM graphics consoles at the same time and monitor.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:

FIELD SERVICE ENGINEER and CUSTOMER ACTIVITY:

1. Verify all expected hardware is visible to the server and the fault is cleared. Assistance from the customer for server login access will be required.

2. Verify there are no outstanding faults in ILOM:

# ipmitool sunoem cli 'show faulty'
Connected. Use ^D to exit.
-> show faulty
Target | Property | Value
-------------------+-----------------------+-----------------------------------
-> Session closed
Disconnected
#

If there are faults still outstanding that did not auto-clear in ILOM after replacement, refer to the post-repair procedures section of Doc ID 1155200.1 to clear the fault.

3. Verify there are no outstanding alerts in the Database Node:

# dbmcli -e list alerthistory

4. Re-enable and restart the Database services:

If running Linux or Solaris native - follow Steps 11 to 14 of MOS Note:
How to shutdown the Exadata database nodes and storage cells in a rolling fashion so certain hardware tasks can be performed. (Doc ID 1539451.1)

If running OVM then follow MOS Note:
How to Shutdown and Startup Exadata compute nodes running OVM (Doc ID 2367609.1)
