Click Reconfigure.
Storage Manager Pro reconfigures the array using your
selected drives. You can continue using the array while Storage
Manager Pro reconfigures it even though the reconfiguration
may take several hours to complete, depending on the array
type, size of the array, and the I/O load. See Viewing Task
Progress on page 6-5.
After you expand the size of an array, you must also use Disk
Administrator to make the additional space available to users.
Note:
If you are adding drives to a RAID 5 set, your
data will not be redundant until the reconfiguration
process is completed.

Changing Array Settings or Properties

You can change the following array settings or properties:
I
Array Name. Type a new name.
I
Array size. See Expanding Array Capacity on page 3-2.
I Write cache. See Changing the Write Cache Properties on
page 3-4.
Note:
As a precaution, you should back up array data before
making changes to the array.

Changing the Write Cache Properties

You can change the array write cache properties. The read and write
cache share the same memory location on the controller. The cache
options work only if you are using a controller that supports
caching.
Write cache speeds write operations by temporarily storing write
data in cache until the disk drives are available to write the data.
Read cache speeds read operations by storing recently read or
written data in cache and by reading ahead in the data.
