NOTE:
The type of con
guration may not apply to all supported storage components and serves only as an
example providing basic guidance.
Create disk arrays—On storage servers with congurable storag e, physical disks can be
arranged as RAID arrays for fault tolerance and enhanced performance, and then segmented into
logical disks of appropriate sizes for particular storage need s. These logical disks then become
the volumes tha t appear as drives on the stora g e server.
CAUTION:
The rst two logical drives are congured for the storage server operating system and should not be
altered in any manner. If the rst two logical drives are altered, the system recov ery process may not
function properly when using the System Recovery DV D. Do not tamper with the “DON’T ERASE” or
local C: volume. These are reserved volumes and must be maintained as they exist.
The fault tolerance level depends on the amount of disks selected when the array was created. A
minimum of t wo disks is required for RAID 0+1 conguration, three disks for a RAID 5 conguration,
andfourdisksforaRAID6(ADG)conguration.
Create logical disks from the array space—Sele ct the desired fault tolerance, stripe size, and
size of the logical disk.
Verify newly crea ted lo g ical disks—Verify that disks m atching the newly created sizes are
displayed.
Create a volume on the new logical disk—Select a drive letter and enter a volume label, volume
size, allocation unit size, and mount point (if desired) .
Storage management utilities
The storage ma nagement utilities preinstalled on the storage server include the HP Array Conguration
Utility (ACU).
Array management utilities
Storage devices for RAID arrays and LUNs are created and mana ged using the array management
utilities mentioned previously. For HP Smart Arrays use the ACU .
NOTE:
The ACU is used to congure and manage array-based storage. Software RAID-based storage servers
use Microsoft Disk Manager to manage storage. You need administrator or root privileges to run the
ACU.
