VMware vSAN is a software-defined storage solution that simplifies and optimizes the storage of virtual machines. vSAN 6.0 is the latest version of vSAN that introduces many new features and enhancements, such as fault domains, all-flash disk groups, stretched clusters, and more.
If you are running an older version of vSAN, you may want to upgrade to vSAN 6.0 build 42, which is the latest patch that fixes some issues and improves performance and stability. In this article, we will show you how to upgrade to vSAN 6.0 build 42 in a few easy steps.
Step 1: Check the requirements
Before you start the upgrade process, make sure that your hardware and software meet the minimum requirements for vSAN 6.0. You can find the detailed requirements in VMware KB 2106708. Here are some of the main points:
All hardware used for vSAN must be on the VMware HCL.
All ESXi hosts in the vSAN cluster must be running ESXi 6.0.
All ESXi hosts must have a vmkernel port configured for vSAN traffic.
Layer 2 multicast must be enabled on the physical switch connecting all hosts in the vSAN cluster.
Each host must have at least one SSD or PCIe flash disk for caching and at least one HDD or SSD for data storage.
Step 2: Backup your data
Although vSAN is designed to protect your data from failures, it is always a good practice to backup your data before performing any major changes to your environment. You can use any backup solution that supports VMware vSphere, such as VMware Data Protection, Veeam Backup & Replication, or others. Make sure that you backup all your virtual machines and their configuration files.
Step 3: Update vCenter Server
The first step of the upgrade process is to update your vCenter Server to version 6.0 build 42 or later. You can download the latest version of vCenter Server from VMware Downloads. Follow the instructions in vSphere Upgrade Guide to perform the update.
Step 4: Update ESXi hosts
The next step is to update your ESXi hosts to version 6.0 build 42 or later. You can use various methods to update your hosts, such as VMware Update Manager, esxcli commands, or ISO images. You can find the latest version of ESXi from VMware Downloads. Follow the instructions in vSphere Upgrade Guide to perform the update.
Step 5: Update vSAN disk format
The final step is to update the vSAN disk format to version 6.0. This step is optional but recommended, as it enables some of the new features and enhancements of vSAN 6.0. To update the disk format, you need to use the RVC command-line tool on your vCenter Server appliance or Windows machine. Follow the instructions in vSAN Administration Guide to perform 061ffe29dd
