Activate license on an air-gapped cluster using Cluster UUID

Get your Cluster UUID and contact Portworx. The Cluster UUID information is available via pxctl cluster list command.

pxctl cluster list

Cluster ID: MY_FAVORITE_PX_CLUSTER
Cluster UUID: f987ad4b-987c-4e7e-a8bd-788c89cc40f1
Status: OK [...]

Upon supplying the Cluster UUID, you receive your license file. Upload this file on one of the Portworx nodes, and activate the license by running the following command:
```
pxctl license add license_file.bin
```

Note:

The license installation is a non-obtrusive process, which does not interfere with the data stored on the Portworx volumes, nor interrupts the active IO operations.
If you’re running Portworx on an air-gapped cluster that has no outbound connectivity, refer to this page for enabling pay-as-go billing.
Once you enable a pay-as-you-go license on an air-gapped cluster with no outbound connectivity, you currently can’t switch to any other license.
