Configurable and pre-configured storage
Certain storage servers ship with storage configured only for the operating system. The administrator must
configure data storage for the storage server. Other storage servers ship with pre-configured storage for
data. Depending on the type of storage server purchased, additional storage configuration is required.
Configuring additional storage involves creating arrays, logical disks, and volumes.
general task areas to be performed as well as the utilities needed to configure storage for an HP Smart
Array-based storage server.
Table 9 Tasks and utilities needed for storage server configuration
Task
Create disk arrays
Create logical disks from the array space
Verify newly created logical disks
Create a volume on the new logical disk
NOTE:
The type of configuration may not apply to all supported storage components and serves only as an
example providing basic guidance.
• Create disk arrays—On storage servers 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 server.
CAUTION:
For hardware RAID-based storage servers, the first controller has logical drives pre-configured under
Array A. These logical drives are configured for the storage server operating system and should not
be altered in any manner.
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 5 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).
NOTE:
Do not tamper with the "DON'T ERASE" or local C: volume. These are reserved volumes and must
be maintained as they exist.
