VMFS datastores serve as repositories for virtual machines. You can set up VMFS datastores on any SCSI-based storage devices that the host discovers, including Fibre Channel, iSCSI, and local storage devices.
Launch the vSphere Client and log in to a vCenter Server system.
Before creating datastores, you must install and configure any adapters that your storage requires. Rescan the adapters to discover newly added storage devices.
- Log in to the vSphere Client and select the host from the Inventory panel.
- Click the Configuration tab and click Storage in the Hardware panel.
- Click Datastores and click Add Storage.
- Select the Disk/LUN storage type and click Next.
- Select a device to use for your datastore and click Next.
Important: Select the device that does not have a datastore name displayed in the VMFS Label column. If a name is present, the device contains a copy of an existing VMFS datastore.
- Select the File System Version and click Next.
