Removing Dead Segments
Does my controller support this feature? See Supported Features.
The Remove Dead Segments task recovers disk space that is unusable. A dead or orphaned disk segment refers to an area of a physical disk or physical device that is unusable for any of the following reasons:
- The dead segment is an area of the physical disk or physical device that is damaged.
- The dead segment is included in a virtual disk, but the virtual disk is no longer using this area of the physical disk or physical device.
- The physical disk or physical device contains more than one virtual disk. In this case, disk space that is not included in one of the virtual disks may be unusable.
- The dead segment resides on a physical disk or physical device that has been disconnected and then reconnected to the controller.
