Managing Systems and Workgroups: A Guide for HP-UX System Administrators

Planning a Workgroup
Setting Disk-Management Strategy
Chapter 280
LVM divides up the disk in much the same way as the “hard partitions”
implemented under earlier versions of HP-UX for systems, but logical
volumes are very much easier to reconfigure than partitions, and they
can span two or more disks. These two attributes make LVM a much
more powerful and flexible tool than hard partitions.
VERITAS Volume Manager (VxVM)
The VERITAS Volume Manager provides alternative online disk
management to the HP Logical Volume Manager and HP MirrorDisk/UX
products. The VERITAS Volume Manager is included on the HP-UX 11i
Application CD and, as of the September 2002 release of HP-UX 11i
version 1, VxVM is included in the operating environments and enables
VxVM rootability. With VxVM rootability, you can choose to configure
your root volume during installation with Ignite-UX, or you can use the
conversion tools installed with VxVM to configure your root volume at a
later time. For more information and details, read HP-UX 11i
