VERITAS Volume Manager 3.5 Release Notes (August 2002)

Chapter 1

VERITAS Volume Manager™ Release Notes

Overview of VxVM 3.5 for HP-UX

• CVM infrastructure changes to support VERITAS Cluster File System

New Features in VxVM 3.5

• GAB messaging

In a cluster environment, support has been included for using GAB as the transport agent for messaging.

This means that you do not need to assign IP addresses for the endpoints of your cluster’s private network

when you conﬁgure the clustering functionality of VxVM.

• Large ﬁle system support

VxVM now supports the use of 64-bit block numbers with ﬁle systems that can understand these.

• Rootability Support

The capability to allow the VERITAS Volume Manager to manage the root disk selectable at installation

time.

• New licensing package

A new licensing package, VRTSvlic, has been introduced. In time VRTSvlic will become the common

licensing solution for all VERITAS products. Existing license keys are automatically translated into

license keys that can be used with the VRTSvlic package. Both licensing packages can co-exist on the

same system to support older VERITAS products that do not understand the new licensing utilities. For

more information, see the VERITAS Volume Manager 3.5 Installation Guide.

• VxVM tunables

The values of various tunables have been adjusted to match the performance expected from current

systems. For more information about conﬁguring VxVM tunables, see the “Performance Monitoring and

Tuning” chapter in the VERITAS Volume Manager 3.5 Administrator’s Guide.

• VERITAS Enterprise Administrator (VEA)

VEA replaces the VERITAS Volume Manager Storage Administrator (VMSA) as the graphical

conﬁguration tool for VxVM.

NOTE For information about new features in VERITAS Volume Replicator (VVR), please see the

VVR Release Notes.
