  Error message:
  mmvdisk: Creating file system 'testfs'.
  mmvdisk: (mmcrfs) Incorrect option: -p afmMode
  
  There is an issue in mmvdisk when process '--mmcrfs'.
  It processes two option model: --opt value and
  --opt=value.
  Because the option value of '-p' includes '=', mmvdisk
  splits its value
  'afmMode=RO,afmTarget=gpfs:///gpfs/testfs_src/ '  into
  two parts 'afmMode' and
  'RO,afmTarget=gpfs:///gpfs/testfs_src/' by mistake.
  That why mmcrfs reports Incorrect option: -p afmMode'.
  
  
  Reported in: 5.1.6
  

Local fix

• Use the format "-p=afmMode=..." to overcome the issue for

  two parts 'afmMode' and 'RO,afmTarget=gpfs:///gpfs/ssoft_src/'
  by mistake.That why mmcrfs reports Incorrect option: -p
  afmMode'.
