Reconfiguring A Virtual Disk
Does my controller support this feature? See Supported Features.
The Reconfigure task enables you to change the virtual disks properties. For example, you can use this task to add physical
disks or change the RAID level.
Format, Initialize, Slow, And Fast Initialize
Does my controller support this feature? See Supported Features.
The Format, Initialize, Slow Initialize, or Fast Initialize task enables you to erase the files and remove the file systems on a
virtual disk. Some controllers require that you initialize a virtual disk before it can be used.
Canceling Background Initialization
Does my controller support this feature? See Supported Features.
The Cancel Background Initialization task enables you to cancel a background initialization on a virtual disk.
On PERC controllers, background initialization of redundant virtual disks begins automatically after the virtual disk is created.
Because the initialization is run in the background, other processes can continue while the initialization completes.
The background initialization of a redundant virtual disk prepares the virtual disk for parity information and improves write
performance. It is important that the background initialization is allowed to run to completion. You can, however, cancel the
background initialization. When you do so, the controller restarts the background initialization later.
NOTE: Cancel Background Initialization virtual disk task is not supported on SWRAID controllers.
Restoring Dead Segments
Does my controller support this feature? See Supported Features.
The Restore Dead Segments task recovers data from a RAID-5 virtual disk that has been corrupted. The Restore Dead
Segments task attempts to reconstruct data from the corrupt portion of a physical disk included in a RAID-5 virtual disk. The
Restore Dead Segments task uses the parity or redundant information to reconstruct the lost data. This task is not always
able to recover lost data.
Deleting Data On the Virtual Disk
Does my controller support this feature? See Supported Features.
The Delete task destroys all data on the virtual disk.
Performing A Check Consistency
Does my controller support this feature? See Supported Features.
The Check Consistency task verifies the accuracy of the redundant (parity) information. This task only applies to redundant
virtual disks. When necessary, the Check Consistency task rebuilds the redundant data. If the virtual disk is in a Failed
Redundancy state, running a check consistency may be able to return the virtual disk to a Ready state.
