HP ProLiant Storage Server User Guide (440584-003, September 2007)

NOTE:

This section addresses only single storage server node conﬁgurations. If your server has Windows

Storage Server 2003 R2 Enterprise Edition, see the Cluster Administration chapter for expand ing and

extending storage in a cluster environment.

Expanding storage

Expansion is the process of adding physical disks to an array that has already been con ﬁgured. The

logical drives (or volumes) that exist in the array before the expansion takes place are unchanged,

because only the amount of free space in the array changes. The expansion process is entirely

independent of the operating system.

NOTE:

See your storage array hardware user documentation for further details about expanding storage on

the array.

Extending s

torage using Windows Storage Utilities

Volume exte

nsion grows the storage space of a logical drive. During this process, the administrator adds

new storage

space to an existing logical drive on the same array, usually after the array has b een

expanded. An administrator may have gained this new storage space by either expansion or by deleting

another logical drive on the same array. Unlike drive expansion, the operating system must be aware

of changes to the logical drive size.

You extend

avolumeto:

• Increase raw data storage

• Improve performance by increasing the number of spindles in a logical drive volume

• Chan ge fa

ult-tolerance (RAID) conﬁgurations

For more i

nformation about RAID levels, see the Smart Arr a y Contr oller User Guide,orthedocument

titled Assessing R AI D ADG vs. R AI D 5 vs. RAID 1+0. Both are available at the Smart Array controller

web page or at h

documentation.html.

Extend volumes using Disk Management

The Disk Management snap-in provides management of hard disks, volumes or partitions. It can be

used to extend a dy namic volume only.

NOTE:

Disk Management cannot be used to extend basic disk partitions.

Guidelines for extending a dynamic volume:

• Use the Disk Mana gement utility.

• You can extend a volume only if it does not have a ﬁle system or if it is formatted NTFS.

• You cannot extend volumes formatted using FAT or FAT32.

• Yo u cannot extend striped volumes, mirrored volumes, or RAID 5 volumes.
