Veritas Storage Foundation 5.1 SP1 Cluster File System Release Notes (5900-1509, April 2011)

See the Veritas Storage Foundation Installation Guide for more information on
planning and upgrading VVR from a pervious version of IPv4 to IPv6.
Planning and upgrading VVR to use IPv6 as connection protocol
Storage Foundation High Availability supports using IPv6 as the connection
protocol.
This release supports the following configurations for VVR:
■ VVR continues to support replication between IPv4-only nodes with IPv4 as
the internet protocol
■ VVR supports replication between IPv4-only nodes and IPv4/IPv6 dual-stack
nodes with IPv4 as the internet protocol
■ VVR supports replication between IPv6-only nodes and IPv4/IPv6 dual-stack
nodes with IPv6 as the internet protocol
■ VVR supports replication between IPv6 only nodes
■ VVR supports replication to one or more IPv6 only nodes and one or more IPv4
only nodes from a IPv4/IPv6 dual-stack node
■ VVR supports replication of a shared disk group only when all the nodes in
the cluster that share the disk group are at IPv4 or IPv6
Changes related to Veritas File System
Veritas File System includes the following changes:
Autolog replay on mount
The mount command automatically runs the VxFS fsck command to clean up the
intent log if the mount command detects a dirty log in the file system. This
functionality is only supported on file systems mounted on a Veritas Volume
Manager (VxVM) volume.
Dynamic Storage Tiering is rebranded as SmartTier
In this release, the Dynamic Storage Tiering (DST) feature is rebranded as
SmartTier.
FileSnap
FileSnaps provide an ability to snapshot objects that are smaller in granularity
than a file system or a volume. The ability to snapshot parts of a file system name
space is required for application-based or user-based management of data stored
