
Use the Cancel Rebuild task to cancel a rebuild while it is in progress.

Change Policy

Does my controller support this feature? See "Supported Features."

Use the Change Policy task to change a virtual disk's read, write, or cache policy. Changes to the read, write, and cache policy only apply to the virtual disk
that you have selected. This task does not change the policy for all virtual disks on the controller. See "RAID Controller Read, Write, Cache, and Disk Cache
Policy" for more information.

You can also modify the physical disk cache policy using this command.

Replace Member Disk

Does my controller support this feature? See "Supported Features."

Use the Replace Member Disk task to copy data from a physical disk, which is a member of a virtual disk, to another physical disk by providing the Replace
Member Configuration option. You can initiate multiple copies of data from different array groups. See "Virtual Disk Task: Replace Member Disk (Step 1 of 2)" for
more information.

Create Virtual Disk Express Wizard (Step 1 of 2)

Does my controller support this feature? See "Supported Features."

The Create Virtual Disk Express Wizard calculates an appropriate virtual disk configuration based on the available space and controller considerations. When
using the Express Wizard, you select the RAID level and size for the virtual disk. The wizard selects a recommended disk configuration for you that matches
your RAID and size selection.

Before creating a virtual disk, you should be familiar with the information in "Considerations Before Creating Virtual Disks". You may also want to review
"Choosing RAID Levels and Concatenation."

If you want to make your own selections for the virtual disk configuration, click Go To Advanced Wizard.

To Create a Virtual Disk Express Wizard: Step 1 of 2
1. Click the radio button to select the correct RAID level.
¡ Depending on the controller, Concatenated enables you to combine the storage capacity of several disks or to create a virtual disk using only a
single physical disk. See "Number of Physical Disks per Virtual Disk" for information on whether the controller supports a single physical disk or
two or more when using Concatenated. Using Concatenated does not provide data redundancy nor does it affect the read and write
performance.
¡ Select RAID 0 for striping. This selection groups n disks together as one large virtual disk with a total capacity of n disks. Data is stored to the
disks alternately so that they are evenly distributed. Data redundancy is not available in this mode. Read and write performance is enhanced.
¡ Select RAID 1 for mirroring disks. This selection groups two disks together as one virtual disk with a capacity of one single disk. The data is
replicated on both disks. When a disk fails, the virtual disk continues to function. This feature provides data redundancy and good read
performance, but slightly slower write performance. Your system must have at least two disks to use RAID 1.
¡ Select RAID 5 for striping with distributed parity. This selection groups n disks together as one large virtual disk with a total capacity of (n-1)
disks. When a disk fails, the virtual disk continues to function. This feature provides better data redundancy and read performance, but slower
write performance. Your system must have at least three disks to use RAID 5.
¡ Select RAID 6 for striping with additional distributed parity. This selection groups n disks as one large virtual disk with a capacity of (n-2) disks.
The virtual disk remains functional with up to two disk failures. RAID 6 provides better read performance, but slower write performance. Your
