Use the  lsvdisk  command to display information about all volumes that are defined within the  IBM Spectrum Virtualize environment. To display more d information about a specific volume,  run the command again and provide the volume name or the volume ID as the command  parameter, as shown in Example 7-1.  The use of the  mkvdisk  command creates sequential, striped, or image mode volumes. When  they are mapped to a host object, these objects are seen as disk drives on which the host can  perform I/O operations.  Creating an image mode disk:  If you do not specify the  -size  parameter when you create  an image mode disk, the entire MDisk capacity is used. You must know the following information before you start to create the volume: GLYPH<SM590000> In which storage pool the volume will have its extents GLYPH<SM590000> From which I/O Group the volume will be accessed GLYPH<SM590000> Which IBM Spectrum Virtualize node will be the preferred node for the volume GLYPH<SM590000> Size of the volume GLYPH<SM590000> Name of the volume GLYPH<SM590000> Type of the volume GLYPH<SM590000> Whether this volume is to be managed by IBM Easy Tier to optimize its performance Chapter 7.
