Base VERITAS Volume Manager (VxVM)
updated for
December 2001
The Base VERITAS Volume Manager 3.2 for HP-UX (swlist version B.03.20) is a new
version of the VERITAS Volume Manager and Cluster Volume Manager with enhanced
features that are currently only available on Solaris, but will soon be available on Linux
and AIX.
Similar to the Base VERITAS Volume Manager 3.1 for HP-UX, this new version includes
the following add-on products:
• B9116AA: VERITAS Volume Manager 3.2 for HP-UX provides a full set of enhanced
volume manager capabilities,including mirroring,RAID-5,andDMPfor active/active
devices.
• B9117AA: VERITAS Volume Manager 3.2 Cluster Volume Manager for HP-UX
provides enhanced volume manager functionality for clustered environments, and is
integrated with MC/ServiceGuard 11.13 and ServiceGuard OPS Edition 11.13. (The
Cluster Volume Manager for HP-UX requires that the VERITAS Volume Manager be
installed first.)
All the software for both the base and add-on products is included in the Base VxVM
product, but the enhanced features are unavailable without a license. When you
purchase an add-on product, you will get a license that enables the enhanced features.
What’s Changed
The Base VERITAS Volume Manager 3.2 for HP-UX will be installed by default on all of
the Operating Environments in the December 2001 release. Customers who purchase
one of these OEs will no longer need to install Base VxVM. However, none of the VxVM
add-on products are available as part of any OEs.
The VERITAS Volume Manager 3.2 includes the following new features:
• enhancements to the Dynamic MultiPathing (DMP) feature via a new Device
Discovery Layer, which makes it easier to add new array support without requiring a
kernel rebuild or a system reboot
• 4-node CVM support for MC/ServiceGuard and ServiceGuard OPS Edition
• CVM and shared disk group support for striped mirrors, online relayout, and Oracle
resilvering
• full support for HP-UX workstations
• performance improvements
