Expanding and Extending Capacity
Caution: Back up all data before removing drives or changing configurations.
Failure to do so could result in permanent loss of data. Before moving drives
and arrays, run the Array Configuration Utility.
Array Capacity Expansion is the addition of physical drives to an array that has
already been configured. The capacity of these added physical drives may then be
added to an existing logical drive on the array (capacity extension; see the next
paragraph), or it may be configured into a new logical drive.
Logical Drive Capacity Extension is the enlargement of an existing logical drive
after the corresponding array has undergone capacity expansion.
Capacity expansion and extension are carried out using ACU. A data backup and
restoration cycle is not required, even in non-fault-tolerant configurations.
If you are using hot-pluggable drives, expansion can be performed online (that is,
without shutting down the operating system). Online extension can only be
performed if supported by the operating system.
Note: When extending a logical drive under Windows 2000, upgrade the disk to
DYNAMIC
before creating a partition on that disk. If the disk already has a partition
when it is upgraded to DYNAMIC, Windows 2000 may not allow logical drive
extension. Refer to the Windows 2000 documentation for details about DYNAMIC and
BASIC disks.
Note: Windows NT 4.0 will only allow four partitions on each logical drive. Additional
drive space created may not be accessible if the four partitions per logical drive limit is
exceeded.
