This section covers the prerequisite steps that are required to use FC as principal storage for workload domain hosts.

Commission hosts for VMFS on FC

Before the workload domain can be created using FC as principal storage, the hosts must be commissioned with the VMFS on FC storage type.

Create the VMFS datastore

The wizard for workload domain creation requires a preconfigured VMFS datastore that is visible to all the ESXi hosts used in the workload domain.

To create the datastore, follow these general steps:

1. Verify that all the workload domain ESXi hosts have been zoned to the storage array.

2. Create a datastore volume and present it to all the workload domain hosts.

Dell storage configuration includes instructions for each Dell storage array.

3. Log in to the web client of one of the ESXi hosts and create the datastore.
   1. Rescan the storage adapters for new storage devices.
   2. Create a VMFS-6 datastore and note the datastore name for workload domain creation later.
4. Log in to the remaining ESXi hosts web client to verify that the hosts can see the new datastore.

Workload domain creation

When you create the workload domain, the storage section of the wizard prompts for the VMFS-6 datastore name that was created previously. If the correct datastore name is not provided, the interface produces an error message like the one shown in the following figure.
