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

When managing disks and volumes:

• The ﬁrst two logical drives are conﬁgured for the storage server o p erating system and should not

be altered in any manner. If the ﬁrst two logical drives are altered, the system recover y process

may not function properly when using the System Recovery DVD. Do not tamper with the “DON’T

ERASE” or loca l C: volume. These are reserved volumes and must be maintained as they exist.

• 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 d rive letter embedded in the volume label, if

possible. (For example, volume e: might be named “Disk E:.”) Volume labels often ser ve 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 d isks can be converted to dynamic, but cannot be converted back to basic without d eleting

all data on the disk.

• Basic disks can co ntain up to four primary pa r titions (or three primary partitions and one

extended partition).

• Format drives with a 16 K allocation size for best support of shadow copies, p erformance,

and defragmentation.

• NTFS formatted drives are recommended, because they provide the greatest level of support for

shadow copies, encryption, and compression.

• Only basic disks can be formatted as FAT or FAT32.

• Read the online D isk Management help found in the utility.

Scheduling defragmentation

Defragmentation is the process of analyzing local volumes and consolidating fragmented ﬁles and folders

so that each occupies a single, contiguous space on the volume. This improves ﬁle system performance.

Because defragmentation consolidates ﬁles and folders, it a lso consolidates the free space on a volume.

This reduces the likelihood that new ﬁles will be fragmented.

Defragmentation for a volume c an be scheduled to occur automatically at convenient times.

Defragmentation can also be done once, or on a recurring basis.

NOTE:

Scheduling defragmentation to run no later than a speciﬁc time prevents the defragmentation process

from running later than that time. If the defragmentation process is running when the time is reached,

the process is stopped. This set ting is useful to ensure that the defragmentation process ends before the

demandforserveraccessislikelytoincrease.
