Before we start the unmapping operation, it is imperative that we unmount the volume from the host. This will ensure that unnecessary alerts are not generated when you remove the volume from the host.
Please note that this is a disruptive operation and if you accidentally unmap the wrong volume from the host then this may result in an outage in your production environment.
- Click on Storage > Volumes and select the volume you wish to unmap from the host.
- Click on Provision > Unmap as shown below.
- Select the host to be unmapped from the volume
- Click on Apply.
