How To Resize VMWare VMDK Disk

• On Windwos, You can use following command to resize the disk

  C:\Program Files\VMware\VMware Server>vmware-vdiskmanager.exe
  VMware Virtual Disk Manager - build 44356.
  Usage: vmware-vdiskmanager.exe OPTIONS diskName | drive-letter:
  Offline disk manipulation utility
    Options:
       -c                   : create disk; need to specify other create options
       -d                   : defragment the specified virtual disk
       -k                   : shrink the specified virtual disk
       -n <source-disk>     : rename the specified virtual disk; need to
                              specify destination disk-name
       -p                   : prepare the mounted virtual disk specified by
                              the drive-letter for shrinking
       -q                   : do not log messages
       -r <source-disk>     : convert the specified disk; need to specify
                              destination disk-type
       -x <new-capacity>    : expand the disk to the specified capacity
  
       Additional options for create and convert:
          -a <adapter>      : (for use with -c only) adapter type (ide, buslogic or lsilogic)
          -s <size>         : capacity of the virtual disk
          -t <disk-type>    : disk type id
  
       Disk types:
          0                 : single growable virtual disk
          1                 : growable virtual disk split in 2Gb files
          2                 : preallocated virtual disk
          3                 : preallocated virtual disk split in 2Gb files
  
       The capacity can be specified in sectors, Kb, Mb or Gb.
       The acceptable ranges:
                             ide adapter : [100.0Mb, 950.0Gb]
                             scsi adapter: [100.0Mb, 950.0Gb]
          ex 1: vmware-vdiskmanager.exe -c -s 850Mb -a ide -t 0 myIdeDisk.vmdk
          ex 2: vmware-vdiskmanager.exe -d myDisk.vmdk
          ex 3: vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 0 destinationDisk.vmdk
          ex 4: vmware-vdiskmanager.exe -x 36Gb myDisk.vmdk
          ex 5: vmware-vdiskmanager.exe -n sourceName.vmdk destinationName.vmdk
          ex 6: vmware-vdiskmanager.exe -k myDisk.vmdk
          ex 7: vmware-vdiskmanager.exe -p m:
                (A virtual disk first needs to be mounted at m:
                 using the VMware Diskmount Utility.)

  WARNING: If the virtual disk is partitioned, you must use a third-party
           utility in the virtual machine to expand the size of the
