Property Denition
The algorithm for calculating the virtual disk size rounds a value of 0.005 or less, down to
0.00 and a value between 0.006 and 0.009, up to 0.01. For example, a virtual disk size of
819.725 is rounded down to 819.72. A virtual disk size of 819.726 is rounded up to 819.73.
Device Name Displays the operating system device name for this object.
Bus Protocol Displays the technology that the physical disks included in the virtual disk are using. Possible
values are:
• SAS
• SATA
Media Displays the media type of the physical disks present in the virtual disk. The possible values
are:
• HDD
• SSD
• Unknown — Storage Management is unable to determine the media type of the
physical disk.
NOTE: You cannot have a mix of HDD and SSD media on a virtual disk. Also, you
cannot have a mix of SAS and SATA drives on the virtual disk.
Read Policy Displays the read policy that the controller is using for the selected virtual disk. See RAID
Controller Read, Write, Cache, and Disk Cache Policy.
Write Policy Displays the write policy that the controller is using for the selected virtual disk. See RAID
Controller Read, Write, Cache, and Disk Cache Policy.
Cache Policy Displays the cache policy that the controller is using for the selected virtual disk. See RAID
Controller Read, Write, Cache, and Disk Cache Policy.
Stripe Size Displays the stripe size of the virtual disk.
Disk Cache Policy Displays whether the disk cache policy of the physical disks that is part of the virtual disk is
enabled or disabled. See RAID Controller Read, Write, Cache, and Disk Cache Policy.
Virtual Disk Tasks
To execute a virtual disk drop-down menu task:
1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2 Expand a Controller object.
3 Select the Virtual Disks object.
4 Select a task from the Available Tasks drop-down menu.
5 Click Execute.
NOTE
: Dierent controllers support dierent features. The tasks displayed on the Available Tasks drop-down box can
vary depending on which controller is selected in the tree view. If no tasks can be performed because of controller or
system conguration limitations, then the Available Tasks drop-down box displays No Task Available.
