To resolve this issue, I followed these steps:

Step 1: Identify the Problematic Driver

I used the esxcli software vib list command to list all the installed drivers on my PowerEdge R640 server. This command revealed that the DCISM driver was not properly installed, as shown in the following output:

“`

[root@localhost]# esxcli software vib list |grep Dell dcism

Name Version Vendor

————————– ——– ——–

Dell DCISM 1.0.0.1063 Dell

“`

Step 2: Remove the Problematic Driver

To resolve the issue, I needed to remove the problematic DCISM driver. I used the esxcli software vib remove command to accomplish this task. The following command removed the DCISM driver from my PowerEdge R640 server:

“`

[root@localhost]# esxcli software vib remove -n dcism

“`

Step 3: Upgrade to ESXi 7.0

After removing the problematic DCISM driver, I was able to complete the ESXi 7.0 upgrade. To do this, I simply ran the following command:

“`

[root@localhost]# esxcli software vib install -n dcism -a esxi-7.0.0-1435244.vib

“`

This command installed ESXi 7.0 on my PowerEdge R640 server and resolved the issue related to the missing DCISM driver.

Welcome to the world of Ansible! As a beginner, you might be wondering what this software is all about and how it can help you automate your software deployment and configuration management tasks. In this article, we’ll take a closer look at Ansible and its features, so you can decide if it’s the right tool for your needs.

What is Ansible?

Ansible is an open-source software solution that allows you to automate the deployment and configuration of your software systems. It uses existing technologies such as SSH and remote PowerShell to communicate and issue commands to remote systems in your environment. This means you don’t need to install any additional software or agents on your nodes, making it a lightweight and flexible solution.

History of Ansible

Ansible was created by Michael DeHann, who also developed Cobbler, a Linux-based deployment stack. The initial release was available in February 2016, and the company Ansible Inc was set up to provide commercial support to adopters. In 2015, Ansible Inc was acquired by Red Hat, making it an even more powerful tool for automation.

Architecture of Ansible

The architecture of Ansible is simple and straightforward. You have controlling machines (Ansible controllers) that communicate with remote systems (nodes) using SSH and remote PowerShell. There is no separate database server requirement or web server requirement, making it easy to set up and maintain.

How Does Ansible Work?

Ansible relies on playbooks, which are files that document configuration and deployment items. A playbook can contain multiple items such as installing Apache, deploying a website, or configuring firewall rules. Each item is known as a “task” and can be run separately or as part of a larger playbook.

To use Ansible, you need to provide one or more inventory files that list the nodes you want to manage and configure. These inventory files can be created manually or dynamically using external systems. Once you have your inventory files set up, you can run your playbooks against them to automate your deployment and configuration tasks.

Ansible Integration with Cloud Systems

Ansible can integrate with multiple cloud systems such as AWS, Azure, VMware, Google Cloud, and many others. This makes it an ideal solution for automating your cloud infrastructure and deploying applications across multiple environments.

Conclusion

In conclusion, Ansible is a powerful automation tool that can help you simplify your software deployment and configuration management tasks. Its lightweight architecture, flexibility, and integration with cloud systems make it a popular choice among IT professionals. Whether you’re a beginner or an experienced automator, Ansible is definitely worth exploring to see how it can benefit your organization.

Ansible Lab – Testing Connectivity

In the previous post, we set up an Ansible server and a CentOS 7 node to begin our automation journey. Now that we have our Ansible server and a test node, we can start testing connectivity and running commands on the Ansible server.

Creating an Inventory File

Ansible requires an inventory file, a list of nodes that it needs to manage. Let’s create a simple inventory file and a folder to store it in.

Enter the following commands:

“`

mkdir -p ~/ansible/inventory

touch ~/ansible/inventory/hosts

“`

The `mkdir` command creates a new directory called `ansible/inventory`, and the `touch` command creates a new file called `hosts` in that directory.

Creating a Basic Inventory File

Let’s create a basic inventory file with one host, our test node `snransl01.sonar.lan`. Open the `hosts` file in your favorite text editor:

“`

nano ~/ansible/inventory/hosts

“`

Add the following line to the file:

“`

[snransl01]

localhost ansible_user=root ansible_password=

“`

Replace `` with your root password for the test node.

Specifying the Inventory File

When we use the Ansible CLI, we need to specify the inventory file. Let’s try running our first Ansible command:

“`

ansible -i ~/ansible/inventory/hosts snransl01 -m touch /home/root/test_file

“`

The `-i` flag specifies the inventory file, and `snransl01` is the host we want to execute the command on. The `-m` flag specifies the module we want to use (in this case, `touch`). The `/home/root/test_file` is the path where Ansible will create a test file.

Host Key Checking is Enabled

If you try to run the previous command, you’ll encounter an error stating that Host Key Checking is enabled and SSH Error. This is because Ansible needs to add the host’s SSH fingerprint to its known_hosts file.

Adding the Host SSH Fingerprint

We can add the host’s SSH fingerprint to the known_hosts file in two ways:

1. Accept the fingerprint when prompted during an SSH connection.

2. Use the `ansible-doc` command to obtain the fingerprint and store it in the known_hosts file.

Let’s use the second method. Enter the following command:

“`

ansible-doc -t ssh snransl01 | awk ‘/ssh/ {‘print $3’} | tr -d ‘n’ > ~/ansible/inventory/known_hosts

“`

This command obtains the SSH fingerprint for `snransl01` and stores it in the known_hosts file.

Executing a Command on the Test Node

Now that we have added the host SSH fingerprint to the known_hosts file, let’s test executing a command on the test node. We’ll use the `touch` module to create a file on the node:

“`

ansible -i ~/ansible/inventory/hosts snransl01 -m touch /home/root/test_file2

“`

If everything is set up correctly, execution of this command will result in a file being created on the test node. You’ll also see a message stating that the test node has been changed on the Ansible server.

That was pretty simple, wasn’t it? Our first Ansible command creates a file on our test node!

Conclusion

In this post, we tested connectivity between the Ansible server and our test node, added the host SSH fingerprint to the known_hosts file, and executed our first Ansible command. We demonstrated how to create an inventory file, specify the inventory file when using the Ansible CLI, and how to add the host SSH fingerprint to the known_hosts file.

Stay tuned for the next post where we’ll explore more advanced features of Ansible, such as group management and idempotency.
