How to Replace an Exadata X7-2 Storage Cell Server Front Indicator Module and/or Cable.

Solution

DISPATCH INSTRUCTIONS:

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?: Exadata X7-2 Training

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:  An Exadata X7-2 Storage Cell Server Front Indicator Module (FIM) and/or FIM Cable 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 storage cell is required prior to the part replacement:

Complete Steps 1 to 6 of Note ID 1188080.1 “Steps to shut down or reboot an Exadata storage cell without affecting ASM”.

Where noted, the SQL, CellCLI and commands under ‘root’ should be run by the Customers DBA, unless the Customer provides login access to the Field Engineer

These steps are also provided in the documentation:

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.

Removing the Front Indicator Module and Cable

1. Disconnect the LED indicator module cable from the motherboard. 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 11 to access the LED indicator module motherboard cable connection. To ease removal of the LED indicator module cable, slightly lift the SAS cable bundles from the cable trough along the left side of the chassis.

2. Remove the three No. 2 Phillips screws that secure the FIM cable and Temp Sensor Access cover to the chassis.

3. Lift up and remove the FIM cable and Temp Sensor Access cover from the FIM cable and Temp Sensor Access cover slot. Set aside the FIM cable and Temp Sensor Access cover.

4. Remove the two No. 2 Phillips screws that secure the LED indicator module to the server front panel.

5. Remove the LED indicator module and cable from the server front panel.

6. Remove the LED indicator module cable by carefully pulling the cable through the cable trough along the left side of the chassis.

Installing the Replacement Front Indicator Module and Cable

1. Unpack the replacement FIM and/or Cable.

2. Push the LED indicator module and cable through the LED housing on the server front panel.

3. Install the LED indicator module cable by carefully pulling the cable through the cable trough along the left side of the chassis. Note - To ease installation of the LED indicator module cable, slightly lift the SAS cable bundles from the cable trough along the left side of the chassis.

4. Insert and tighten the two No. 2 Phillips screws to secure the LED indicator module to the server front panel.

5. Install the FIM cable and Temp Sensor Access cover to the chassis by inserting it into the FIM cable and Temp Sensor Access cover slot being careful not to damage the temperature sensor when installing the FIM cable and Temp Sensor Access cover to the chassis.

6. Install the three No. 2 Phillips screws to secure the FIM cable and Temp Sensor Access cover to the chassis

7. Reconnect the LED indicator module cable to the motherboard. 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 11 to access the LED indicator module motherboard cable connection.

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:

3. Verify there are no outstanding alerts in the Cell:

4. Re-activate the Storage Cell grid disks.  Follow Steps 7 to 10 of Note ID 1188080.1 “Steps to shut down or reboot an Exadata storage cell without affecting ASM”.

Where noted, the SQL, CellCLI and commands under ‘root’ should be run by the Customers DBA, unless the Customer provides login access to the Field Engineer.
