Which edition of vSphere are using ? DRS won't work on standard edition. Please follow below link for more information

VMware vSphere 5.1 ESXi Licensing issues.

Problem

You try to assign a license key to an ESXi host, but you cannot perform the operation and you receive an error message.

Cause

You might be unable to assign a license key to an ESXi host because of the following reasons:

■	The calculated license usage for the host exceeds the license capacity. For example, you have a vSphere Essentials license key with capacity for two processors. You try to assign the key to a host that has four processors. You cannot assign the key, because the required license usage for the host is four processors.
■	The features on the host do not match the license edition. For example, you might configure vMotion and DRS on a cluster of hosts while you are using evaluation mode. Later, you try to assign Standard license keys to the hosts. This operation fails because the Standard edition does not include vMotion and DRS.
■	You do not apply the correct license key.
■	The host is connected to a vCenter Server system that is assigned a license key that restricts the edition of the license that you want to assign. For example, vCenter Server is licensed with vCenter Server Standard, and the license key is for vSphere Essentials.

Solution

■	Assign a license key with larger capacity.
■	Upgrade the license edition to match the resources and features on the host, or disable the features and resources that do not match the license edition.
■	Assign a correct license key. To license ESXi hosts, you must assign a vSphere license key.
■	Assign a license key whose edition is compatible with the license edition of vCenter Server. For example, if vCenter Server is licensed with vCenter Server Standard, you need a vSphere Standard license key.

Good Day

This is a screen shot of my cluster licenses which has two hosts , I already assigned license to one of the vsphere hosts (192.168.10.13).

But When I tried to assign license to vsphere host (192.168.10.14), I got the following error message (vsphere DRS in use, you must turn off this feature.

When I tried to disable DRS, I got this error message “license not available to perform this operation”

Need your support in solving this problem soon please.

I see, this seems to be due to the DRS you might have enabled during evaluation mode.

Disconnect it from vCenter (make sure you remove it from vCenter as well) and directly connect to host using vSphere client. Go to Configuration > Licensing feature > Edit

Remove if you have evaluation key there and add new license key. After that re-add host to vCenter.
