Creating a Transparent Volume
Transparent volumes
cannot be used in
further volume
hierarchies.
Tape devices must
be virtualized as
transparent volumes.
You can take a physical disk and its existing configured storage data and
convert it to a directly accessible, or transparent, virtual volume using the
CLI command volume create transparent. A transparent volume is
ready for direct host exposure. Please refer to Chapter 7 “
Volume
Exposure & Security ”.
Certain vendor storage devices have vendor-specific SCSI commands. To
support these SCSI commands, you can convert these storage devices and
their contained data to transparent volumes.
This is useful if you have a functioning and fully configured RAID module
that you want to use ’as is’. All RAID configurations will be maintained in
the transparent volume.
