VERITAS Volume Manager

This release of VERITAS Volume Manager includes new features and enhancements.

Intelligent Storage Provisioning (ISP)

The Intelligent Storage Provisioning (ISP) service is an alternative to the traditional method of

creating and managing volumes. ISP creates volumes from available storage with capabilities that

you specify by consulting the externally defined rule base for creating volumes, and comparing it to

the properties of the storage that is available. Because ISP is very rich in functionality, there is a

new separate Administrator’s Guide titled VERITAS Volume Manager Intelligent Storage

Provisioning Administrator’s Guide.

Note Volumes created with the vxassist utility can be migrated for use with ISP. After

migration, volumes can no longer be administered using vxassist.

Dynamic Multipathing Enhancements

There are a number of enhancements in the area of the Dynamic Multipathing (DMP) feature:

◆ You can now use the vxdmpadm setattr command to change the I/O policy for

distributing I/O load across multiple paths to a disk array or enclosure. You can set policies for

an enclosure, for all enclosures of a particular type, or for all enclosures of a particular array

type (Active/Active or Active/Passive). Once configured, the I/O policies are persistent across

reboots of the system. For more information, see the “Administering Dynamic Multipathing

(DMP)” chapter of the VERITAS Volume Manager Administrator’s Guide.

◆ With this release, the generic framework within the Device Discovery Layer (DDL) enables

Dynamic Multipathing (DMP) to coexist with other third party multi-pathing drivers such as

EMC PowerPath.

◆ Failback is now a cluster-wide operation that provides significant performance improvements.

◆ A/PF type arrays are now supported by DMP in a clustered environment.
