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.

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.
