User's Manual

Does my controller support this feature? See Supported Features.
Use the Reconfigure task to change the virtual disks properties. For example, you can use this task to add physical disks or change the RAID level. For more
information, see Virtual Disk Task: Reconfigure (Step 1 of 3).

Format, Initialize, Slow and Fast Initialize

Does my controller support this feature? See Supported Features.
Use the Format, Initialize, Slow Initialize, or Fast Initialize task 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. For more information, see Format and Initialize; Slow and Fast Initialize.

Cancel Format or Initialize

Does my controller support this feature? See Supported Features.
Use the Cancel Format or Cancel Initialize task to cancel the virtual disk format or initialize while it is in progress. For more information on virtual disk format
or initialize, see Format and Initialize; Slow and Fast Initialize.

Cancel Background Initialization

Does my controller support this feature? See Supported Features.
On PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di 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 be allowed to run to completion. You can, however, cancel the background initialization. When you do so, the controller restarts the
background initialization at a later time. For more information, see Background Initialization on PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di Controllers.
Use the Cancel Background Initialization task to cancel a background initialization on a virtual disk.

Restore Dead Segments

Does my controller support this feature? See Supported Features.
Use the Restore Dead Segments task to recover data from a RAID-5 virtual disk that has been corrupted. The Restore Dead Segments task attempts to
reconstruct data from a 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.

Delete

Does my controller support this feature? See Supported Features.
Use the Delete task to destroy all data on the virtual disk. For more information, see Virtual Disk Task: Delete.

Assign and Unassign Dedicated Hot Spare

Does my controller support this feature? See Supported Features.
Use the Assign Dedicated Hot Spare task to assign a disk as a backup for a single virtual disk. For more information, see Assign and Unassign Dedicated Hot
Spare.

NOTE: The Cancel Initialize task only applies to the PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di controllers.
NOTE: On the PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di controllers, the controller firmware uses the rebuild rate setting to control the system
resource allocation for the Background Initialization task. For more information, see Set Rebuild Rate.
