What’s New with Veritas Storage Foundation 5.0
Veritas™ Storage Foundation 5.0 includes the Veritas™ File System (VxFS) and the Veritas™
Volume Manager (VxVM). New features and enhancements for VxFS and VxVM that are
supported in the SG SMS version 2.0 for HP-UX 11i v3 bundles are as follows:
What’s New with Veritas File System (VxFS)
As of April 2008, the following new features and enhancements included with VxFS are supported
in the SG SMS version 2.0 for HP-UX 11i v3 bundles:
• Support for Large Directories — VxFS 5.0 introduces an alternate indexing mechanism to
improve the performance of file system operations on directories with a large number of
entries.
• File Change Log — The VxFS File Change Log (FCL) tracks changes to files and directories
in a file system. The FCL can be used by applications, such as backup products, web crawlers,
search engines, indexing engines and replication software that typically scan an entire file
system searching for modification since a previous scan. This feature was introduced with
the VxFS 4.1 release on HP-UX 11i v3. FCL is supported only on file systems with Disk
Layout Version 6 or above.
• File-to-Volume and Volume-to-File Mapping in Multi-volume File Systems — supported
with two new commands:
— fsmap (reports the volume location of all data, or indirect extents associated with a file
in a multi-volume file system, and verifies that DST policies are working as requested)
— fsvmap (determines which data file is resident on a given volume for a multi-volume
file system and recovers only the affected files when an unprotected volume is
permanently lost)
