Create new VMFS Volume:

1. Formating Partition:

#fdisk -u /vmfs/devices/disks/naa.60901234567890123456789012345678

Type p and press Enter to list partition information.
Type d and press Enter to delete existing partition information.
Type n and press Enter for new partition.
Type p and press Enter for a primary partition.
Type 1 and press Enter.
For the First cylinder prompt, press Enter for the default.
For last cylinder or +size, press Enter for the default.
Type t and press Enter to change volume type.
Type 1 and press Enter to select the first partition.
Type fb and press Enter.
###  Note: fb is the hexadecimal code for VMFS volumes.
Type x and press Enter to enter Expert mode.
Type b and press Enter to start the process of changing the starting block of the partition.
Type 1 and press Enter to select the first partition.
Type 128 and press Enter to set the starting block to 128.
Type w and press Enter to save the changes and exit fdisk.

2. To list the newly created partition information:
#fdisk -lu /vmfs/devices/disks/naa.60901234567890123456789012345678

3. For ESXi 5.0 you can create a datastore with the VMFS-5 file system using the command:

#vmkfstools -C vmfs5 -b 1m -S NewDatastore /vmfs/devices/disks/naa.60901234567890123456789012345678:1
