Solution

DISPATCH INSTRUCTIONS:

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

TIME ESTIMATE: 30 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Exadata X7-2 Compute Node Server Coin Cell Battery 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.

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.

Removing the Coin Cell Battery

Caution - Ensure that all power is removed from the server before removing or installing the battery. You must disconnect the power cables from the system before performing these procedures.

1. The battery is located in a retainer directly behind the PCIe slot 1 riser. To dislodge the battery from its retainer, gently push the top edge of the battery away from the retainer.
2. Gently lift the battery up and out of the retainer.

Installing the Coin Cell Battery

1. Unpack the replacement battery.
2. Press the new battery into the battery retainer so that the + positive side faces the plastic of the retainer and the - negative side is making contact with the metal clip.

Return the Server to Operation

1. Install the server top cover.
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. The service processor is configured to synchronize with a network time server using the Network Time Protocol (NTP), the Oracle ILOM clock will be reset as soon as the server is powered on and connected to the network. Login to the server as 'root' user and verify the correct time and date and timezone in the OS and in ILOM:

# date
Fri Mar 2 11:25:34 EST 2018
# ipmitool sunoem cli 'show /SP/clock'
Connected. Use ^D to exit.
-> show /SP/clock

/SP/clock
Targets:

Properties:
datetime = Fri Mar 2 11:25:54 2018
timezone = EST (America/New_York)
uptime = 24 days, 20:07:17
usentpserver = enabled

Commands:
cd
set
show

-> Session closed
Disconnected
#

3. 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
#

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

# dbmcli -e list alerthistory

5. 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)
