Configuring data storage
HP StorageWorks X1000 and X3000 Network Storage Systems are configured only for the operating
system. The administrator must configure data storage for the storage system.
Configuring additional data storage involves creating arrays, logical disks, and volumes. Table 13
shows the general task areas to be performed as well as the utilities needed to configure storage for
an HP Smart Array-based storage system.

• Create disk arrays—On storage systems 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 sizes for particular storage needs. These logical disks then become the volumes
that appear as drives on the storage system.
CAUTION:
The first two logical drives are configured for the storage system 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 RAID 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—Select 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 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 management utilities preinstalled on the storage system include the HP Array Configuration
Utility (ACU).
