HMC media device driver

Edit online

7.1 LPAR mode z/VM guest

You use the HMC media device driver to access files on removable media at a system that runs the Hardware Management Console (HMC).

Before you begin: You must log in to the HMC on the system with the removable media and assign the media to the LPAR.
As of System z10®, the HMC media device driver supports the following removable media:
  • A DVD in the DVD drive of the HMC system
  • A CD in the DVD drive of the HMC system
  • USB-attached storage that is plugged into the HMC system
The most commonly used removable media at the HMC is a DVD.
The HMC media device driver uses the /dev/hmcdrv device node to support these capabilities:
  • List the media contents with the lshmc command.
  • Mount the media contents as a file system with the hmcdrvfs command.

Installers on suitably prepared installation DVDs can use these capabilities to install Linux® in an LPAR.
