ESX Server 3 Configuration Guide : Using vmkfstools

Using vmkfstools
You use the vmkfstools utility to create and manipulate virtual disks, file systems, logical volumes, and physical storage devices on the VMware ESX Server hosts. Using vmkfstools, you can create and manage virtual machine file system (VMFS) on a physical partition of a disk. You can also use the command to manipulate files, such as virtual disk files, stored on VMFS-2, VMFS-3, and NFS.
You can perform most vmkfstools operations using the VI Client. For information on using the VI Client to work with storage, see Configuring Storage.
