23		file		The path to the backing file for the LUN.
24				Required if LUN is not marked as removable.
25		ro		Flag specifying access to the LUN shall be
26				read-only. This is implied if CD-ROM emulation
27				is enabled as well as when it was impossible
28				to open "filename" in R/W mode.

30				being removable.
31		cdrom		Flag specifying that LUN shall be reported as
32				being a CD-ROM.
33		nofua		Flag specifying that FUA flag

40				result in ejection.
