If you want to monitor the progress of the build operation, display
the Array Group Information window for the new array group. The
build progress is displayed as a percentage of completion in the
Status field. You can also view the Information window for an array
that is a member of a multilevel RAID to monitor the progress for
that component of the multilevel RAID.
Naming an Array Group
In the Array Group Information window, click Name to assign a
unique name to an array group or multilevel RAID. This name is
displayed under the Array icon and other locations that display the
array identifier. The name can be 1 to 13 characters in length.
Note: You must restart the host computer before the new
array name takes effect.
Expanding and Extending Arrays – Windows 2000 and Windows NT only
The following definitions are used in this section:
Array expansion—Adding additional space to an existing
array group using the array expansion feature.
Volume extension—Adding the new space created by the
array expansion to the existing Windows volume (LSU).
Array expansion enables you to increase your storage capacity by
adding one or more drives to your RAID 0 and RAID 5 arrays while
your system remains online. As additional drives are added, the
controller redistributes the data on the array, placing the new space
at the end of the LSU and increasing the size of the logical drive.
Before array expansion was available, to increase the size of an array
you had to backup the data on the array, shutdown the host system,
delete the old array, and then build a larger array that included the
new drives. After the larger array was built, you would reinstall the
operating system (if necessary) and restore the data from the
backup. This entire process could keep your system off-line for at
least one day and possibly longer.
