Prerequisites




Before you download and install ESXi 7.0 Update 3d, you need to make sure that:


  • Your server is compatible with ESXi 7.0. You can check the VMware Compatibility Guide for more information.



  • You have a VMware Customer Connect account to access the download page.



  • You have backed up your data and configuration settings on your existing ESXi host.



  • You have migrated or shut down any virtual machines running on your ESXi host.



Step 1: Download the ESXi 7.0 Update 3d ISO image from VMware website




To download the ESXi installer, follow these steps:


  • Log in to .



  • Navigate to Products and Accounts > All Products.



  • Find VMware vSphere and click Download Product.



  • Select a VMware vSphere version from the Select Version drop-down menu.



  • Select a version of VMware vSphere Hypervisor (ESXi) and click GO TO DOWNLOADS.



  • Download an ESXi ISO image.



Step 2: Verify the checksum of the downloaded ISO image




To ensure that the downloaded ISO image is not corrupted or tampered with, you need to verify the checksum of the ISO image. A checksum is a unique value that is calculated from the data in a file. If the checksum of the downloaded file matches the checksum provided by VMware, it means that the file is intact and authentic.


To verify the checksum of the ISO image, follow these steps:


  • Locate the checksum value for the ISO image on the VMware download page. It is usually displayed as a SHA-1 or MD5 hash.



  • Use a checksum tool to calculate the checksum of the downloaded file. You can use a built-in tool in your operating system or a third-party tool. For example, on Windows, you can use .



  • Compare the checksum values. If they match, it means that the file is valid and safe to use. If they do not match, it means that the file is corrupted or modified and you need to download it again.



Step 3: Create a bootable USB drive or burn a DVD with the ISO image




To install ESXi 7.0 Update 3d on your server, you need to create a bootable media with the ISO image. You can use a USB drive or a DVD for this purpose.


To create a bootable USB drive with the ISO image, follow these steps:

FAQs




Here are some frequently asked questions about ESXi 7.0 Update 3d:


  • How can I check the current version and build number of my ESXi host?



You can check the current version and build number of your ESXi host by using one of the following methods:


  • Log in to the ESXi host using a web browser and navigate to Host > Monitor > System > Summary.



  • Log in to the ESXi host using SSH or the DCUI and run the command vmware -v.



  • Log in to vCenter Server using a web browser and navigate to Hosts and Clusters > Select your ESXi host > Configure > System > System Information.



  • How can I update multiple ESXi hosts at once?



If you have multiple ESXi hosts in your environment, you can use one of the following methods to update them at once:


  • Use VMware Update Manager (VUM), which is a tool that automates the patching and upgrading of ESXi hosts. You can create a baseline with the ESXi 7.0 Update 3d ISO image and attach it to your hosts or clusters. Then you can scan and remediate your hosts to apply the update. You can also use VUM to schedule the update or use maintenance mode to avoid impacting your virtual machines.



  • Use VMware vSphere Lifecycle Manager (vLCM), which is a tool that simplifies the lifecycle management of ESXi hosts. You can create a desired state image with the ESXi 7.0 Update 3d ISO image and assign it to your hosts or clusters. Then you can check and remediate your hosts to apply the update. You can also use vLCM to monitor the compliance and drift of your hosts.



  • Use VMware PowerCLI, which is a command-line and scripting tool that allows you to automate the management of ESXi hosts. You can use the cmdlets Get-EsxCli and Install-VMHostPatch to update your ESXi hosts with the ESXi 7.0 Update 3d ISO image. You can also use PowerCLI to perform other tasks such as putting your hosts into maintenance mode, rebooting them, or verifying their version and build number.



  • How can I roll back to a previous ESXi version if I encounter any issues with ESXi 7.0 Update 3d?



If you encounter any issues with ESXi 7.0 Update 3d, you can roll back to a previous ESXi version by using one of the following methods:


  • Use the Shift+R option during boot, which allows you to revert to the previous boot bank of your ESXi host. This option is available only if you have not rebooted your host more than twice after installing the update.



  • Use the DCUI option, which allows you to restore your ESXi host from a backup configuration file. This option is available only if you have enabled the Auto Deploy service and created a backup configuration file before installing the update.



  • Use the reinstall option, which allows you to reinstall your ESXi host from a bootable media with a previous ESXi version. This option will overwrite your existing configuration and data, so make sure that you have backed them up before proceeding.
