Some ACU guidelines to consider:
•
Do not modify the single logical drive of the storage system; it is configured for the storage
system operating system.
•
Spanning more than 14 disks with a RAID 5 volume is not recommended.
•
Designate spares for RAID sets to provide greater protection against failures.
•
RAID sets cannot span controllers.
•
A single array can contain multiple logical drives of varying RAID settings.
•
Extending and expanding arrays and logical drives is supported.

Disk Management utility
The Disk Management tool is a system utility for managing hard disks and the volumes, or partitions,
that they contain. Disk Management is used to initialize disks, create volumes, format volumes with
the FAT, FAT32, or NTFS file systems, and create fault-tolerant disk systems. Most disk-related tasks
can be performed in Disk Management without restarting the system or interrupting users. Most
configuration changes take effect immediately. A complete online help facility is provided with the
Disk Management utility for assistance in using the product.
NOTE:
•
When the Disk Management utility is accessed through a Remote Desktop connection, this
connection can only be used to manage disks and volumes on the server. Using the Remote
Desktop connection for other operations during an open session closes the session.
•
When closing Disk Management through a Remote Desktop connection, it may take a few
moments for the remote session to log off.
Guidelines for managing disks and volumes
•
The single logical drive is configured for the storage system operating system and should not
be altered in any manner. If this logical drive is altered, the system recovery process may not
function properly when using the System Recovery DVD. Do not tamper with the local C:
volume. This is a reserved volume and must be maintained as it exists.
•
HP does not recommend spanning array controllers with dynamic volumes. The use of software
RAID-based dynamic volumes is not recommended. Use the array controller instead; it is more
efficient.
•
Use meaningful volume labels with the intended drive letter embedded in the volume label, if
possible. (For example, volume e: might be named “Disk E:.”) Volume labels often serve as
the only means of identification.
•
Record all volume labels and drive letters in case the system needs to be restored.
•
When managing basic disks, only the last partition on the disk can be extended unless the
disk is changed to dynamic.
•
Basic disks can be converted to dynamic, but cannot be converted back to basic without
deleting all data on the disk.
•
Basic disks can contain up to four primary partitions (or three primary partitions and one
extended partition).
•
Format drives with a 16 K allocation size for best support of shadow copies, performance,
and defragmentation.
•
NTFS formatted drives are recommended because they provide the greatest level of support
for shadow copies, encryption, and compression.
