Veritas Storage Foundation 5.1 SP1 for Oracle RAC Release Notes (5900-1513, April 2011)

■ Veritas Volume Replicator (VVR) commands including vxibc, vxrlink,

vxrsync, vxrvg, vrport, vrstat, and vradmin.

■ The vxdisk command.

Changing the CVM master online

Cluster Volume Manager (CVM) now supports changing the CVM master from

one node in the cluster to another node, while the cluster is online. CVM migrates

the master node, and reconfigures the cluster.

Symantec recommends that you switch the master when the cluster is not handling

VxVM configuration changes or cluster reconfiguration operations. In most cases,

CVM aborts the operation to change the master, if CVM detects that any

configuration changes are occurring in the VxVM or the cluster. After the master

change operation starts reconfiguring the cluster, other commands that require

configuration changes will fail.

To change the master online, the cluster must be cluster protocol version 100 or

greater.

Dynamic Storage Tiering is rebranded as SmartTier

In this release, the Dynamic Storage Tiering (DST) feature is rebranded as

SmartTier.

Online migration of a native file system to VxFS file system

The online migration feature provides a method to migrate a native file system

to the VxFS file system. The migration takes minimum amounts of clearly bounded,

easy to schedule downtime. Online migration is not an in-place conversion and

requires a separate storage. During online migration the application remains

online and the native file system data is copied over to the VxFS file system.

See the Veritas Storage Foundation Advanced Features Administrator's Guide.

Cross-platform data sharing support for disks greater than 1 TB

Previous to this release, the cdsdisk format was supported only on disks up to 1

TB in size. Therefore, cross-platform disk sharing (CDS) was limited to disks of

size up to 1 TB. Veritas Volume Manager (VxVM) SF Oracle RAC 5.1 SP1 removes

this restriction. VxVM SF Oracle RAC 5.1 SP1 introduces CDS support for disks

of size greater than 1 TB as well.
