4 Chapter: Expanding a Windows
Volume on the SAN
Overview
Often times storage administrators need to expand volumes on a Windows
server. Whether company growth, new requirements or changes in
infrastructure, administrators require a SAN solution flexible enough to
accommodate their changing storage needs. This section details the necessary
steps to grow a basic disk on Windows 2000 or Windows 2003. Dynamic disks
are outside of the scope of this document and not recommended for use with
the LeftHand SAN. Growing a disk in the LeftHand SAN is a simple 2-step
process that can be performed while the volumes are still on-line and
accessible to applications/users
Increasing the Volume Size via the CMC
Any volume residing on the LeftHand SAN has the ability to increase in size.
This operation is completed via the Centralized Management Console and
consists of the following steps:
1 Launch the CMC
2 Select the volume to increase
3 Double click to bring up the Edit Volume window
4 Adjust the volume size, hard threshold and soft threshold accordingly
Once the volume size has been increased on the SAN, steps must be performed
in order for Windows to expand the partition to use the full space available on
the disk.
Increasing the Volume Size in Windows
Windows Logical Disk Manager, the default disk management program that is
included in any Windows installation, uses a tool called Diskpart.exe to grow
volumes from within Windows.
