of data, you can extend the logical drive when there is free space on the array. If no
free space is available on the array, you can add drives to the array and proceed to
extend the logical drive.

IMPORTANT: Logical drive extension is not supported by all operating systems. Only extend
logical drives that are used with an operating system that supports extension.

Extending Logical Drives — Operating Systems

The following operating systems support logical drive extension:

• Microsoft Windows 2000 with Service Pack 3
• Microsoft Windows Server 2003

If your operating system is not listed, check your operating system documentation or
contact the operating system vendor before extending logical drives.

RAID Level and Stripe Size Migration

Use the Online RAID Level or Stripe Size Migration screen to:

• Reconfigure a currently configured logical drive to a new fault-tolerance

(RAID) level.

• Change the stripe size of an existing logical drive to a new stripe size.

Both migrations can be executed online on Windows 2000 or Windows Server 2003
without causing data loss. These migrations can also be performed offline on other
operating systems by booting the SmartStart CD and running the ACU.
