vmkfstools is one of the ESXi Shell commands for managing VMFS volumes, storage devices, and virtual disks. You can perform many storage operations using the
vmkfstools command. For example, you can create and manage VMFS datastores on a physical partition, or manipulate virtual disk files, stored on VMFS or NFS datastores.
After you make a change using the
vmkfstools, the vSphere Client might not be updated immediately. Use a refresh or rescan operation from the client.
