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 a volume to:
• Increase raw data storage
• Improve performance by increasing the number of spindles in a logical drive volume
• Change fault-tolerance (RAID) con fi gurations
For more information about RAID levels, refer to the Smart Array Controller User Guide , or the document
titled Assessing RAID ADG vs. RAID 5 vs. RAID 1+0 . Both are available at the Smart Array controller
web page or at http://h18000.www1.hp.com/products/servers/proliantstorage/arraycontrollers/

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 dynamic volume only.
NOTE:
Disk Management cannot be used to extend basic disk partitions.
Guidelines for extending a dynamic volume:
• Use the Disk Management or DiskPart utility.
• You can extend a volume only if it does not have a fi le system or if it is formatted NTFS.
• You cannot extend volumes formatted using FAT or FAT32.
• You cannot extend striped volumes, mirrored volumes, or RAID 5 volumes.
Extend volumes using DiskPart
The DiskPart utility allows the administrator to manage disks at the command line level. Use the utility to
perform disk-related tasks at the command line as an alternative to using Disk Management.
Guidelines for extending a basic volume:
• Use the DiskPart utility.
• To extend a basic volume, it must be formatted NTFS.
• You can only extend a basic volume onto the same disk.
• You can only extend a basic volume if it is followed by contiguous unallocated space.
