Veritas File System 5.0 Release Notes, HP-UX 11i v3, First Edition, May 2008

NOTE: To enable the DST feature an additional license is required. The DST feature is not
available with Base-VxFS and HP OnlineJFS. See Table 1-3 for the products which bundle
this license.
• 2K volumes in a volume set
The limit on the number of volumes allowed in a volume set is now increased from 256 to
2048.
NOTE: 2K volumes are not supported with Base-VxFS and HP OnlineJFS. See Table 1-3
for the products that bundle this license.
• File placement policy administration
The fsppadm command administers the file placement policies of the DST feature, and
replaces the functionality of the fsrpadm, fsmove, and fssweep commands.
See the fsppadm(1M) manual page.
• Pattern-based allocation policies
Pattern tables can be assigned to directories or file systems. A pattern table contains patterns
against which a file's name and creating process' UID and GID are matched as a file is created
in a specified directory. The first successful match is used to set the allocation policies of the
file.
• Load balancing
An allocation policy with the balance allocation order can be defined and assigned to files
that must have their allocations distributed at random between a set of specified volumes.
The effect is that the distribution of extents between the volumes is mostly equal if none of
the volumes are full or disabled.
• Support for Oracle Resilvering
VxFS is enhanced to prevent double re-syncs in the presence of Oracle resilvering. In addition,
this feature provides performance improvement to the Oracle recovery process on mirrored
volumes.
NOTE: To enable the Oracle resilvering feature an additional license is required. The Oracle
resilvering feature is not available with Base-VxFS and HP OnlineJFS. See Table 1-3 for the
products that bundle this license.
• File System Reorganization Prevention
Some applications may require preventing extent and log reorganization. such applications
can disable file system reorganization using the fsadm command by creating the /etc/
vx/vxfs_noreorg_config file.
For information on the syntax of the configuration file, see the fsadm_vxfs(1M).
• HP Integrity Virtual Machine Support
All HP Serviceguard Storage Management Suite products (or product bundles) support HP
Integrity Virtual Machine versions 3.0, 3.5, and 4.0. The Accelerated Virtual I/O (AVIO)
feature is not supported at this time, and must not be configured. AVIO will be supported
only when QXCR1000805037 is resolved.
