using virtual optica drives in VIOS (IBM virtual I/O server)

• first, create a logical volume in which you want the iso-files to be stored:
  

    mkrep -sp rootvg -size 16G
  

  rootvg can also be an other volume group
  the created logical volume is mounted under /var/vio/VMLibrary
• copy your iso-files to this location (or use

    mkvopt -name filename.iso -dev cd0 -ro
  

  to copy the contents of what is in your cd-drive to filename.iso)
• create a virtual optical drive connected to virtual scsi adapter vhost4 (the virtual scsi host for the LPAR to which you want to connect the new virtual optical drive):

    mkvdev -fbo -vadapter vhost4
  

  which will give: "vtopt0 Available"
• connect an iso-file to your virtual optical drive (for example the 'vtopt0' you created with the mkvdev command in the previous step)

    loadopt -vtd vtopt0 -disk filename.iso
  

• disconnect the iso-file (as if you were unloading a cd from the drive):

    unloadopt -vtd vtopt0
