How To Add Lun In Vmware Esxi
Are you looking to expand the storage capacity of your VMware ESXi environment? Adding logical unit numbers (LUNs) can be a crucial step in achieving that goal. By integrating additional storage space, you can ensure that your virtual machines have the necessary resources to run efficiently. In this guide, we will explore how to add LUNs in VMware ESXi, providing you with the knowledge and steps needed to successfully expand your storage capabilities.
To add LUNs in VMware ESXi, it is vital to understand the process and its significance. LUNs are logical representations of physical storage devices, such as hard drives or solid-state drives, that can be connected to your ESXi host. These LUNs serve as storage containers for your virtual machines, allowing you to allocate disk space and manage your data efficiently. By adding LUNs to your VMware ESXi environment, you can increase storage capacity, improve performance, and ensure high availability for your virtual infrastructure.
If you're looking to add a Logical Unit Number (LUN) in VMware ESXi, follow these steps:
- Log in to the vSphere Client and select your ESXi host.
- Navigate to the "Storage" tab and click on "Add Storage."
- Choose the desired storage type (e.g., Fibre Channel, iSCSI, NFS) and click "Next."
- Specify the LUN details, such as the LUN ID or name, and click "Next."
- Review the summary and click "Finish" to add the LUN to your ESXi host.
Understanding LUN and VMware ESXi
Before we delve into the process of adding LUN in VMware ESXi, let's first understand what LUN and ESXi are.
LUN stands for Logical Unit Number. It is a unique identifier that is assigned to a specific logical unit, which can be a disk, tape drive, or other storage device. LUNs are used in storage area networks (SANs) to provide access to data on storage devices.
VMware ESXi, on the other hand, is a type-1 hypervisor that allows virtual machines to run on a physical server. It provides a virtualization layer that abstracts the underlying hardware and enables the efficient allocation and management of resources.
Now that we have a basic understanding of LUN and VMware ESXi, let's move on to the process of adding LUN in VMware ESXi.
Step 1: Prepare the Storage Device
The first step in adding LUN in VMware ESXi is to prepare the storage device. This involves configuring the storage device and presenting the LUN to the ESXi host.
To configure the storage device, you need to access its management interface. This can be done through a web browser or a dedicated management software provided by the storage vendor. Once you are in the management interface, you will need to create a LUN and configure its properties, such as size and access permissions.
After configuring the storage device, you will need to present the LUN to the ESXi host. This is usually done by mapping the LUN to the host's HBA (Host Bus Adapter) or storage controller. The specific steps for presenting the LUN may vary depending on the storage device and ESXi version.
Step 2: Configure ESXi to Discover the LUN
Once the storage device and LUN are prepared, you need to configure ESXi to discover the LUN. This involves configuring the storage adapter settings and enabling the LUN discovery feature.
To configure the storage adapter settings, you will need to access the ESXi host's management interface. From there, you can navigate to the storage adapter settings and configure the appropriate settings for the HBA or storage controller that is connected to the LUN.
In addition to configuring the storage adapter settings, you also need to enable the LUN discovery feature. This feature allows ESXi to scan the storage adapters and detect any newly presented LUNs. Once the LUN is discovered, it will be added to the list of available storage devices in ESXi.
Step 3: Add the LUN to a Storage Group
After the LUN is discovered by ESXi, the next step is to add the LUN to a storage group. A storage group is a logical grouping of LUNs that can be assigned to a particular virtual machine or cluster of virtual machines.
To add the LUN to a storage group, you will need to access the storage settings in the ESXi management interface. From there, you can create a new storage group or add the LUN to an existing storage group. Once the LUN is added to the storage group, it will be available for use by the assigned virtual machines.
It is important to note that the specific steps for adding the LUN to a storage group may vary depending on the version of VMware ESXi you are using. It is recommended to refer to the official documentation or consult with VMware support for detailed instructions.
Step 4: Configure the LUN in ESXi
Once the LUN is added to a storage group, the final step is to configure the LUN in ESXi. This involves formatting the LUN, creating a datastore, and assigning it to the virtual machines.
To format the LUN, you will need to access the storage settings in the ESXi management interface. From there, you can select the LUN and choose the format option. This will create a file system on the LUN, allowing it to be used as a datastore.
After formatting the LUN, you can create a datastore by selecting the LUN and choosing the create datastore option. This will initialize the datastore and make it available for use by the virtual machines.
Once the datastore is created, you can assign it to the virtual machines by configuring the storage settings of the virtual machines. From there, you can select the datastore and assign it as a storage location for the virtual machines' virtual disks.
Conclusion
Adding LUN in VMware ESXi involves a series of steps, including preparing the storage device, configuring ESXi, adding the LUN to a storage group, and configuring the LUN in ESXi. By following these steps, you can successfully add LUNs to your ESXi environment and make them available for use by your virtual machines.

After adding LUNs in VMware ESXi, you can manage and monitor them through the following methods:
- Access the VMware ESXi host's web client or vSphere client.
- Navigate to the storage section and view the added LUNs.
- You can view information about the LUNs, such as storage capacity, datastore name, and status.
- Perform tasks like resizing LUNs, deleting LUNs, or managing LUN access permissions.
- Monitor the performance and health of the LUNs through performance charts and alerts.
It is important to regularly monitor the LUNs for any issues or resource utilization to ensure optimal storage performance in VMware ESXi.
5. Can I remove a LUN from VMware ESXi?
Yes, you can remove a LUN from VMware ESXi if it is no longer needed or if you want to reconfigure the storage environment.
To remove a LUN from VMware ESXi, follow these steps:
- Access the VMware ESXi host's web client or vSphere client.
- Navigate to the storage section and select the LUN you want to remove.
- Click on the "Unmount" or "Remove" option for the selected LUN.
- Confirm the action and wait for the LUN to be unmounted or removed from the ESXi host.
- It is important to ensure that no virtual machines or data are dependent on the LUN before removing it.
By removing a LUN, you free up storage resources and can make changes to the storage configuration according to your requirements.
Adding a LUN in VMware ESXi is a straightforward process that allows you to expand your storage resources and improve the performance of your virtual machines. By following a few simple steps, you can successfully add a LUN and start incorporating it into your infrastructure.
