You can also use VxVM to dynamically configure storage while the system is active. VxVM provides the tools to improve performance and ensure data availability and integrity. This allows volumes to span multiple disks and LUNs. VxVM overcomes restrictions imposed by hardware disk devices and by LUNs by providing a logical volume management layer. Additionally, VxVM provides features that enhance fault tolerance and fast recovery from disk failure or storage array failure. By supporting the Redundant Array of Independent Disks (RAID) model, VxVM can be configured to protect against disk and hardware failure, and to increase I/O throughput. VxVM provides easy-to-use online disk storage management for computing environments and Storage Area Network (SAN) environments. Insert the VxVM CD-ROM in the CD-ROM drive on the node.

Become superuser on a cluster node that you intend to install with VxVM. You will now be asked which depots should be installed. Have available your VxVM installation documentation. A VxVM volume appears to applications and the operating system as a physical device on which file systems, databases and other managed data objects can be configured. Obtain any Veritas Volume Manager (VxVM) license keys that you need to install. Veritas TM Volume Manager (VxVM) by Symantec is a storage management subsystem that allows you to manage physical disks and logical unit numbers (LUNs) as logical devices called volumes.
