Ta bl e 7 Tasks and utilities needed for storage ser ver configuration
Task Storage management utility
Create disk arrays
HP Array Configuration Utility or Storage Manager
Create logical disks from the array space HP Array Configuration Utility or Storage Manager
Verify newly created logical disks
Windows Disk Management
Create a volume on the new logical disk Windows Disk Management
NOTE:
The type of configuration may not apply to all supported storage components and ser ves only as an
example providing basic guidance.
• Create disk arrays—On storage ser vers with configurable storage, physical disks can be
arranged as RAID arrays for fault tolerance and enhanced performance, and then segmented into
logical disks of appropriate s izes for particular storage needs. These logical disks then become
the volumes that appe ar as drives on the storage ser ver.
CAUTION:
The first two logical drives are configured for the storage server operating system and should not be
altered in any manner. If the first two logical drives are altered , the system recovery process may not
function properly when using the System Recovery DVD. 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 two disks is required for R A ID 0+1 configuration, three disks for a RAID 5
configuration, and four disks for a RAID 6 (ADG) configuration.
• Create logical disks from the array space—Sele ct the desired fault tolerance, stripe size, and
size of the logical disk.
• Verify newly created logical disks—Verify that disks matching the newly created sizes are
displayed.
• Create a volume on the new lo g ical disk—Select a drive let ter and enter a volume label, volume
size, allocation unit size, and mount point (if desired).
Storage management utilities
The stora ge management utilities preinstalled on the storage server include the HP Array Configuration
Utility (ACU).
Array management utilities
Storage devices for RAID arrays and LUNs are created and managed using the array management
utilities mentioned prev iously. F or HP Smart Arrays use the ACU .
NOTE:
The ACU is used to configure and manage array-based storage. Software R AID-based storage servers
use Microsoft Disk M anager to manage storage. You need administrator or root privileges to run the
ACU.
Arr ay Confi guration Utility
The HP ACU supports the Smart Array controllers and SCSI hard drives installed on the storage server.
