Re: Why we need to use vmkfstools?

Hi, maybe help this command

The following examples assume you are specifying connection options, either  explicitly or, for example, by specifying the server, user name, and password.  Run vmkfstools --help for a list of common options including connection options. The examples use single quotes around some names; use double quotes on Windows.

Create the specified file system:

For ESX/ESXi version earlier than 4.0, specify the VMHBA name:

  vmkfstools <conn_options> -C vmfs3 -b 1m -S Test vmhba0:0:0:3

For ESX/ESXi version 4.0 or later, specify the device name, for example naa.xxx:

  vmkfstools <conn_options> -C vmfs3 -b 1m -S Test naa.600601604d521c002732ff0dc122dd11:3

Create a virtual disk:

  vmkfstools <conn_options> -c 2048m '[storage1] rh6.2.vmdk'

Rename files associated with a specified virtual disk to the specified name:

  vmkfstools <conn_options> -E '[storage1] rh6.2.vmdk' '[storage1] testing2.vmdk'

Get the geometry information (cylinders, heads, and sectors) of a virtual disk:

  vmkfstools <conn_options> -g '[storage1] testing2.vmdk'

Delete an existing virtual disk:

  vmkfstools <conn_options> -U '[storage1] testing2.vmdk'

Shrink the size of the virtual disk:

 vmkfstools <conn_options> -s '[storage1] rh6.2.vmdk'

Extend the virtual disk to specified size, the extended region of the disk grows in eagerzeroedthick format:

 vmkfstools <conn_options> -X 1g -d eagerzeroedthick '[storage1] rh6.2.vmdk'

Initialize the virtual disk with zeros:

 vmkfstools <conn_options> -w '[storage1] rh6.2.vmdk'
