Although we don’t recommend removing the underlying disks from your gateway, you might want to remove a disk from your gateway, for example if you have a failed disk.

You can use the following procedure to remove a disk from your gateway hosted on VMware hypervisor.<a name="CachedLocalDiskUploadBufferSizing-commonRemovingConsoleVMware"></a>

**To remove a disk allocated for the upload buffer (VMware ESXi)**

1. In the vSphere client, open the context (right-click) menu, choose the name of your gateway VM, and then choose **Edit Settings**. 

1. On the **Hardware** tab of the **Virtual Machine Properties** dialog box, select the disk allocated as upload buffer space, and then choose **Remove**.

   Verify that the **Virtual Device Node** value in the **Virtual Machine Properties** dialog box has the same value that you noted previously. Doing this helps ensure that you remove the correct disk.

1. Choose an option in the **Removal Options** panel, and then choose **OK** to complete the process of removing the disk.

## Removing a Disk from a Gateway Hosted on Microsoft Hyper-V

Using the following procedure, you can remove a disk from your gateway hosted on a Microsoft Hyper-V hypervisor.<a name="CachedLocalDiskUploadBufferSizing-commonRemovingConsoleHyperV"></a>

**To remove an underlying disk allocated for the upload buffer (Microsoft Hyper-V)**

1. In the Microsoft Hyper-V Manager, open the context (right-click) menu, choose the name of your gateway VM, and then choose **Settings**. 

1. In the **Hardware** list of the **Settings** dialog box, select the disk to remove, and then choose **Remove**.

   The disks you add to a gateway appear under the **SCSI Controller** entry in the **Hardware** list. Verify that the **Controller** and **Location** value are the same value that you noted previously. Doing this helps ensure that you remove the correct disk. 

   The first SCSI controller displayed in the Microsoft Hyper-V Manager is controller 0.

1. Choose **OK** to apply the change.

## Removing a Disk from a Gateway Hosted on Linux KVM

To detach a disk from your gateway hosted on Linux Kernel-based Virtual Machine (KVM) hypervisor, you can use a `virsh` command similar to the one following. 

```
$ virsh detach-disk domain_name /device/path
```

For more details about managing KVM disks, see documentation of your Linux distribution.
