This DiskPart command is not available in any edition of Windows Vista. |
For examples of how this command can be used, see Examples.
Syntax
create volume raid [size=<n>] disk=<n>,<n>,<n>[,<n>,...] [align=<n>] [noerr]
Parameters
| Parameter | Description |
|---|---|
|
size=<n> |
The amount of disk space, in megabytes (MB), that the volume will occupy on each disk. If no size is given, the largest possible RAID-5 volume will be created. The disk with the smallest available contiguous free space determines the size for the RAID-5 volume and the same amount of space is allocated from each disk. The actual amount of usable disk space in the RAID-5 volume is less than the combined amount of disk space because some of the disk space is required for parity. |
|
disk=<n>,<n>,<n>[,<n>,...] |
The dynamic disks on which to create the RAID-5 volume. You need at least three dynamic disks in order to create a RAID-5 volume. An amount of space equal to size=<n> is allocated on each disk. |
|
align=<n> |
Aligns all volume or partition extents to the closest alignment boundary. n is the number of kilobytes (KB) from the beginning of the disk to the closest alignment boundary. |
|
noerr |
For scripting only. When an error is encountered, DiskPart continues to process commands as if the error did not occur. Without this parameter, an error causes DiskPart to exit with an error code. |
Remarks
- After you create the volume, the focus automatically shifts to
the new volume.
Examples
To create a RAID-5 volume of 1000 megabytes in size, using disks 1, 2 and 3, type:
create volume raid size=1000 disk=1,2,3
