CD commands

Commands for working with physical CD/DVD drives on XenServer hosts.

CD parameters

CDs have the following parameters:

Parameter Name	Description	Type

uuid	unique identifier/object reference for the	read only
	CD

name-label	Name for the CD	read/write

name-description	Description text for the CD	read/write

allowed-operations	A list of the operations that can be	read only set parameter
	performed on this CD

current-operations	A list of the operations that are currently	read only set parameter
	in progress on this CD

sr-uuid	The unique identifier/object reference for	read only
	the SR this CD is part of

sr-name-label	The name for the SR this CD is part of	read only

vbd-uuids	A list of the unique identifiers for the	read only set parameter
	VBDs on VMs that connect to this CD

crashdump-uuids	Not used on CDs since crashdumps	read only set parameter
	cannot be written to them

virtual-size	Size of the CD as it appears to VMs (in	read only
	bytes)

physical-Utilization	amount of physical space that the CD	read only
	image is currently taking up on the SR (in
	bytes)

type	Set to User for CDs	read only

sharable	Whether or not the CD drive is sharable.	read only
	Default is false.

read-only	Whether the CD is read-only, if false, the	read only
	device is writable. Always true for CDs.

storage-lock	true if this disk is locked at the storage	read only
	level

parent	Reference to the parent disk, if this CD is	read only
	part of a chain
