Creating volumes on specific media types

When you create a volume, you can specify the media type for the volume. The supported media types are Hard Disk Drives (HDD) or Solid State Devices (SSD). The SSD media type requires disk group 150 or greater. The default is HDD.

To specify a media type, specify the vxassist command with the mediatype attribute. If no mediatype is specified, the volume allocates storage only from the HDD devices.
