See Section 3.9, Rescanning Disks for Changes in State, on page 30 for a discussion of when to
rescan disks and the outcomes when doing so.
3.4 Creating Arrays: Future Expansion
When creating arrays, consider whether disk capacity needs to expand in the future. If the file
system must be expanded, perform the tasks indicated in Table 8.
Table 9. Array Expansion Considerations
Operating System
Do This...
And Consider This...
Microsoft
®
Windows
®
Format the arrays with
NTFS. Microsoft
Corporation provides a
utility (Diskpart.exe) that can
dynamically extend an NTFS
file system onto any unused
adjacent space.
Note also that using a single
partition per array makes
expansion much easier.
1. The Diskpart.exe utility version
depends on which version of the
Windows operating system is
running.
2. The Diskpart.exe utility can be
found on the CD for some versions
of Windows operating systems, or on
the Microsoft Corporation website
(http://www.microsoft.com)
for other versions. Use the correct
version for the operating system.
Linux
®
Use an expandable file
system.
Because RAIDXpert2 software is
limited to eight arrays, if a large
number of logical volumes are
needed, use a logical volume
manager (LVM).
3.5 Expanding Disk Capacity Online: Using OCE
(Supported by RAIDXpert2 Plus)
Online Capacity Expansion (OCE) allows:
 Adding disks to an array at any time to increase an array’s capacity.
 Accessing the array data while it is being redistributed.
To increase the size and organization of an array, transform the array. For more information about
transforming arrays, see Section 6.6.3, Transform Arrays (Supported by RAIDXpert2 Plus), on
page 73.
