Oracle Big Data Appliance Base Image Version 4.10.0 for New Installations or Reprovisioning Existing Installations on Oracle Linux 7 (Doc ID 2416137.1)

Last updated on MARCH 02, 2020

Applies to:

Big Data Appliance Integrated Software - Version 4.10.0 and later
Linux x86-64

Purpose

This document provides details for re-imaging the Oracle Big Data Appliance Base Image to Oracle Linux 7 version 4.10.0 . The document describes the steps on how to re-image a single server or an entire Oracle Big Data Appliance or a cluster of BDA servers to Oracle Linux 7 4.10.0.

Note: This BDA Base Image can only be used for reimaging. It does not contain a rescue image (and should not be used on a node that is down unless the goal is to reimage). In other words this base image can not be used to boot a node, only to reimage a node.

Introduction

General

The information in this note is intended to be used by field support or system administrators when re-imaging an Oracle Big Data Appliance on-site with the BDA v4.10.0 OL7 base image. The BDA v4.10.0 OL7 base image is now available in Patch 28218768.

The reimaging steps have not changed from previous images, but new makebdaimage syntax is available to work with clusters using rack-network.json and cluster-network.json.

This OL7 base image supports all BDA hardware generations except for the first-generation BDA M2 servers. 

Clusters will need to be updated to at least BDA v4.10.0 before X7 or X8 servers can be added to the cluster.

New BDAs shipping from the factory have a base image of 4.10.0. But that base image may not be as recent that the 4.10.0 base image provided in Patch 28218768.

Therefore when new BDAs ship from the factory:

1. If the shipped BDAs have a base image older than v4.10.0 then reimage to the 4.10.0 base image in Patch 28218768 as per the instructions in this note.

2. If the shipped BDAs have a base image of v4.10.0 but the v4.10.0 is less than that in Patch 28218768 which is v4.10.0-12 then instead of a full reimage with Patch 28218768 apply the patch in 27441706.

In more detail, when BDA servers arrive at the data center with a v4.10.0 base image less than v4.10.0-12 instead of a full reimage, apply the smaller bda rpm patch to update the base image to v4.10.0-12. This will pick up all the latest base image fixes. The bda rpm patch is in Patch 27441706. Patch 27441706 cannot be used for reimaging, only for updating installed v4.10.0-x base images older than v4.10.0-12.

To install Patch 27441706 follow the instructions in the README or follow the section the MOS note:  How to Download and Install a BDA RPM Patch and Rollback Back to the Original BDA RPM(Doc ID 2379782.1).

Note: Make sure to verify that BDA X7 servers in the field are at BDA base image is 4.10.0-12 before starting network configuration. If they are not, apply Patch 27441706. 

3. If the shipped BDAs have the same base image as that in Patch 28218768, v4.10.0-12 no reimage is required.

Note: you can verify the bda rpm with "rpm -q bda". Output as below indicates the  4.10.0-6  bda rpm. 

b) If the ILOM firmware version is not at least 4.0.2.20, install the bda-4.10.0-12 Oracle Linux 7 bda rpm from the patch below and then update the ILOM firmware using "bdaupdatefw -i"

3. The reimaging steps have not changed from previous images, but new makebdaimage syntax is available to work with clusters using rack-network.json and cluster-network.json.

4. This version contains several fixes over earlier v4.10.0 base images for network configuration and support for newer ILOM firmware. For example 4.10.0-12 contains:

  • Fixes for reimaging.
  • Fixes for OS migration to OL7 - supported on BDA v4.13.0, v4.14.0 and v5.1.0.
  • Support for BDA X8 servers.

       Also included from previous releases are:

  • Support for migrating BDA v4.14.0 Oracle Linux 6 clusters to Oracle Linux 7 (still on BDA v4.14.0).
  • Fixes for bdachecksw to add some disk partition layouts.
  • Fix for OL7 reimaging if the SSD is mounted and in use.
  • Updated HCA/HBA/disk firmware from the Oracle Server X7-2L 1.3.2 release
  • Support for disabling CPU cores on BDA X5 and higher servers.
  • Support for automated replacement of OS and data disks using the bdaconfiguredisk tool.
  • Improved support for migrating BDA v4.13.0 & v4.14.0 Oracle Linux 6 clusters to Oracle Linux 7 (still on the same BDA version).

5. The latest bda rpm patch is 4.10.0-12. It can and should be applied in the field to X7 servers before starting the network configuration. The patch includes bda rpms for both Oracle Linux 6 and Oracle Linux 7 and the appropriate one should be used. The latest available BDA-4.10-0 OL6 and OL7 rpms for updating older base images is available in patch 27441706.

To Summarize

The latest BDA v4.10.0 base image is released as patch 28218768. This is the full base image used for reimaging servers in the field and at the factory currently. The steps to apply Patch 28218768 are provided in this MOS note. They should be used for new installs where the installed base image is older than BDA v4.10.0 or for reprovisioning existing installations where it is desired to wipe the existing cluster to install a new one.
