Device Option icon - a grey box inside another box, Device options

The final tab on the virtual disk Properties dialog box allows you to set some device options for the virtual disk.

Option Description
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. The default disk priority can be changed only after the disk scheduler is changed to “cfq”. It is not available by default. For more information about adjusting QoS settings, and about how QoS control works with different storage types, see Manage storage repositories.
