VMFS datastores are accessed through block protocols, so iSCSI or Fibre Channel connectivity is required. When the communication path has been established, ensure that the VMware ESXi hosts for these datastores are registered. This process can be automated by importing the VMware vSphere information into Unisphere. When this is complete, VMFS datastores can be created.
In the VMFS datastore creation wizard, host access can be configured to ESXi hosts. For any ESXi hosts that are provided access to this datastore, the new storage is automatically rescanned and made available to the ESXi host. Hosts can be given access to the datastore on a LUN level, snapshot level, or both. After the creation of a VMFS datastore, the capacity can be increased, but not reduced.
In Dell Unity OE version 4.3 or later, users can create version 6 VMware VMFS datastores from the Unisphere CLI or REST API. In Dell Unity OE version 4.5 or later, users can create version-5 or version-6 VMware VMFS datastores from Unisphere.
