(The Microsoft OSM does not support array expansion.) ■ RAID 0 or RAID 5 array groups only ■ NTFS file system only. (You cannot extend a volume that has a FAT partition. Instead, you would add the extra space as a separate LSU.) ■ You cannot extend the Windows XP, Windows 2000 or Windows NT boot partition. ■ The array must have Optimal status before beginning the expansion. If the array status is not Optimal, correct the problem and complete a rebuild of the existing array before continuing with expansion. ■ Each new drive added to an array must be at least equal to the capacity of the smallest capacity drive already in the array.

Storage Manager
Requirements and Restrictions
Array expansion has the following system requirements and
restrictions.
■
Windows XP, Windows 2000, Windows NT 4.0, Server or
Workstation, with the most recent service pack.
■
Adaptec supplied driver only. (The Microsoft OSM
does not
support array expansion.)
■
RAID 0 or RAID 5 array groups only
■
NTFS file system only. (You cannot extend a volume that has a
FAT partition. Instead, you would add the extra space as a
separate LSU.)
■
You cannot extend the Windows XP, Windows2000 or
Windows NT boot partition.
■
The array must have
Optimal
status before beginning the
expansion. If the array status is not
Optimal
, correct the problem
and complete a rebuild of the existing array before continuing
with expansion.
■
Each new drive added to an array must be at least equal to the
capacity of the smallest capacity drive already in the array. This
is because in any RAID configuration, the drive with the least
capacity in the array determines the usable capacity of all the
drives in the array. There is no advantage in adding a drive with
a capacity larger than the smallest capacity drive already in the
array.
Expanding an Array Group
To expand an existing array group, follow these steps:
Caution:
Backup your data before changing the configuration
of a disk array. Do not allow power to the host system to be
interrupted while the expansion operation is running.
1
Connect the additional drives to the peripheral bus and power-
on the drives. Refer to the
Adaptec SCSI RAID Installation Guide
if necessary.
