Overview

The Exadata network grid consists of multiple Sun QDR InfiniBand switches.
IB Switches are used for the storage network as well as the Oracle RAC interconnect.
Exadata compute nodes and storage cells are configured with dual-port InfiniBand ports and connect to each of the two leaf switches.
You can access IB Switches using command line and Web ILOM
IB Switches run Linux operating system.

In this article I will demonstrate how to patch or upgrade Oracle Exadata IB Switches.

About Infiniband Switch Patching

Starting with release 11.2.3.3.0, the patchmgr utility is used to upgrade and downgrade the InfiniBand switches.
IB Switch patch is delievered with Exadata storage patch.
IB Switch patches are released semi annually to annually.
IB Switch can be patched in Rolling fashion only.

Environment

Exadata Half Rack X4-2
4 Compute nodes, 7 Storage cells and 2 IB Switches
Current IB Switch Version 2.2.7-1

Step by Step Infiniband Switch Patching

Identify the number of switches in clusters.

[root@dm01dbadm01 ~]# ibswitches

Change root User Password on Exadata Infiniband Switch

By Netsoftmate on

February 18, 2019

- Uncategorized

I was working on changing password for the administrative user accounts on all Exadata Components. I encountered a strange issue while changing the root password on Infiniband Switch. We were unable to change the root password on IB Siwtch using command line method. We used couple different command line methods to change the root password on IB switches but all of them failed. This could be a BUG, firmware issue or something else.

In this article we demonstrate how to change the root password on an Exadata infiniband switch using Browser User Interface.

Issue 1: Using passwd command

Tried to change the root user password using passwd command using dcli. This method assumes you are have ssh equivalence setup from compute node 1. As you can see the command failed saying to use the ILOM shell. In the past I have used the same command successfully to change the root password on IB Switches.

[root@dm01db01 ~]# dcli -g ibswitch_group -l root “echo welcome1 | passwd –stdin root”
dm01sw-ibb01: This command should not be used for ILOM users.
dm01sw-ibb01: Please use ILOM shell to handle password for this user.
dm01sw-ibb01: Example:
dm01sw-ibb01: -> set /SP/users/root password
dm01sw-ibb01:
dm01sw-iba01: This command should not be used for ILOM users.
dm01sw-iba01: Please use ILOM shell to handle password for this user.
dm01sw-iba01: Example:
dm01sw-iba01: -> set /SP/users/root password
dm01sw-iba01:

So I decided to login to the IB switch directly and use the passwd command instead of running from dcli. The passwd command fail again with the same error.

[root@dm01sw-iba01 ~]# ssh dm01sw-ibb01
You are now logged in to the root shell.
It is recommended to use ILOM shell instead of root shell.
All usage should be restricted to documented commands and documented
config files.
To view the list of documented commands, use “help” at linux prompt.

[root@dm01sw-ibb01 ~]# hostname
dm01sw-ibb01

[root@dm01sw-iba01 ~]# passwd root
This command should not be used for ILOM users.
Please use ILOM shell to handle password for this user.
Example:
-> set /SP/users/root password

Issue 2: Using ILOM Shell

As the passwd command failed asking to use the ILOM shell, I login to the IB switch as ilom-admin and executed the change password command. What I see is, the password change command failed at ILOM prompt as well.

[root@dm01sw-iba01 ~]# su – ilom-admin

Oracle(R) Integrated Lights Out Manager
Version 2.2.7-1 ILOM 3.2.6 r118629
Copyright (c) 2017, Oracle and/or its affiliates. All rights reserved.
Warning: HTTPS certificate is set to factory default.

Hostname: dm01sw-iba01

-> set /SP/users/root welcome1
set: Invalid command syntax
Usage: set [-script] [target] <property>=<value> [<property>=<value>…]

Solution: Using Browser User Interface

I have decided to use the BUI to change the password.

Steps:

Open a Browser and enter the IB Switch hostname or IP address

https://dm01sw-ibb01.netsoftmate.com

Accept the security warning and proceed to connect to the IB Switch

Enter the username and password to connect to the IB Switch

This show the summary page

On the left Pan, expand ILOM administration and select User Management

Click on User Accounts, Select root user and click on edit button

Enter the new password and confirm and Finally click on the Save button to change the password.

To Verify the new password, open a Putty session and ssh to IB Switch using new password.

[root@dm01db01 ~]# ssh dm01sw-ibb01
Password:
You are now logged in to the root shell.
It is recommended to use ILOM shell instead of root shell.
All usage should be restricted to documented commands and documented
config files.
To view the list of documented commands, use “help” at linux prompt.

[root@dm01sw-ibb01 ~]# hostname
dm01sw-ibb01

Conclusion

In this article we have learned how to change the root password on Infiniband Switch using Browser User Interface when the command line option doesn’t work.

Patching Exadata Infiniband Switch

By Netsoftmate on

February 12, 2017

- Uncategorized

Overview

The Exadata network grid consists of multiple Sun QDR InfiniBand switches.
IB Switches are used for the storage network as well as the Oracle RAC interconnect.
Exadata compute nodes and storage cells are configured with dual-port InfiniBand ports and connect to each of the two leaf switches.
You can access IB Switches using command line and Web ILOM
IB Switches run Linux operating system.

In this article I will demonstrate how to patch or upgrade Oracle Exadata IB Switches.

About Infiniband Switch Patching

Starting with release 11.2.3.3.0, the patchmgr utility is used to upgrade and downgrade the InfiniBand switches.
IB Switch patch is delievered with Exadata storage patch.
IB Switch patches are released semi annually to annually.
IB Switch can be patched in Rolling and Non-Rolling fashion.

Environment

Exadata Full Rack X2-2
8 Compute nodes, 14 Storage cells and 3 IB Switches
Current IB Switch Version 2.1.5-1

Infiniband Switch Upgrade Steps

Identify the number of switches in clusters.

[root@dm01dbadm01 ~]# ibswitches
