To change the properties of a virtual disk, click on the VM's Storage tab, then select the virtual disk and click Properties.
|Name||The virtual disk name|
|Description||A description of the virtual disk (optional)|
|Folder||The name of the resource folder where the virtual disk is located, if applicable.|
|Tags||A list of tags that have been applied to this virtual disk.|
On the Custom Fields tab you can assign new custom fields to a virtual disk, change the value of any existing custom fields assigned to it, and remove custom fields.
See Using custom fields for information on adding, setting, modifying and deleting custom fields.
Set the size of the virtual disk on this tab and select the storage repository where the virtual disk is located.
The final tab on the virtual disk Properties dialog box allows you to set some device options for the virtual disk.
|Mode||The disk read/write permissions of a virtual disk can be changed, for example, to prevent data from being overwritten on a virtual disk that is being used for backup purposes.|
|Device position||The position to use for this virtual disk in the drive sequence.|
|Disk access priority||For some virtual disks, you may also be able to adjust the disk I/O priority (Quality of Service or QoS). This setting is only available for virtual disks on storage repositories that are LVM-based, that is local, shared iSCSI or hardware HBA. For more information about adjusting QoS settings, and about how QoS control works with different storage types, see the XenServer Administrator's Guide.|
