Goal

 Provide specific additional steps required to successfully replace a Motherboard on a server that is part of an Exadata Database Machine.

Purpose

This note describes what steps to take when a Exadata System Motherboard Replacement is done.

Scope

The note applies to both cells and compute nodes on V2, X2-2, and X2-8 only. Additional documents cover later models.

Solution

DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE ENGINEER NEED:  The engineer must be Exadata trained.
- TIME ESTIMATE: 120 Minutes
- TASK COMPLEXITY: 3

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW

This details the steps required to successfully replace a Motherboard in a server that is part of an Exadata Database Machine.

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

The server node needs to be offlined by the customer's database administrator if it is still operational. This means disabling CRS on a DB node (x4170/x4170m2/x4800) or dropping the disks from ASM on a Storage cell (x4275/x4270m2).

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

The general steps are:
1. Complete the pre-install steps to backup ILOM and gather serial numbers.
2. Physically replace the motherboard per the procedure documented in the server's service manual.
3. Complete the post-install steps to reconfigure the new board to be part of the Exadata

Details

The full procedure to replace an Exadata system board can be found at the following link:
https://support.us.oracle.com/oip/faces/secure/km/DownloadAttachment.jspx?attachid=1336083.1:Exadata_MB_Replace

Please read through this document carefully and follow through each section relevant to the node being serviced. There are individual sections for Storage Cells and DB Compute nodes for each type of Exadata system i.e. V2, X2-2 or X2-8. You only need to complete the sections relevant to the node type.

The described procedure is to be used with the latest EIS Checklist & the Exadata Owner's Guide Documentation that can be found here:

• EIS X2 - http://eis.us.oracle.com/checklists/pdf/Exadata-X2.pdf
• Documentation

You may also need older 2.x and 3.x Firmware versions listed here for V2:

• Sun Fire X4170, X4270, X4275 Firmware and Patch History (Doc ID 1345528.1)

The following steps will be described:

• Backup the current SP configuration
• Update ILOM firmware
• Update Serial Numbers
• Network settings and timezone validation

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

1. Verify the system can boot up into the OS.
2. Ensure the customer's database administrator has successfully been able to either - on a DB node (x4170/x4170m2/x4800) re-enable and start CRS to rejoin the rest of the Exadata Database Machine cluster; or on a Storage Cell (x4275/x4270m2) verify that all ASM grid disks are active and online or syncing.
