HP Serviceguard Storage Management Suite Version A.02.00 for HP-UX 11i v3 Release Notes, April 2008

• Large File Systems and Large File Support — with the HP Online JFS license you can create
file systems over 2 TB and under 32 TB. The EBFS license is required to create file systems
over 32 TB. The EBFS license is bundled with the HP Serviceguard Storage Management
suite. Contact your HP sales representative for information on obtaining this license. For
information on supported file systems and large file support, see the Supported File and File
System Sizes for HFS and JFS white paper available at:
http://docs.hp.com/en/oshpux11iv3.html#VxFS
• Cross Platform Data Sharing (CDS) — allows data to be serially shared among heterogeneous
systems, where each system has direct access to the physical devices that hold the data. This
feature can be used only in conjunction with VxVM
• Concurrent I/O — allows multiple processes to read or write to the same file without blocking
other read(2) or write(2) calls
• Nested Mounts — allows mounting a VxFS file system on any VxFS mount point. A directory
on a shared VxFS file system can be used as a mount point for a VxFS file system, enabling
nested mounts of shared file systems. NOTE: HP Serviceguard does not support CFS nested
mounts.
• Multi-volume File System Availability — allows you to mount a multi-volume file system
even if a component “data-only” volume is missing, or becomes unavailable
• Dynamic Storage Tiering (DST) — allows administrators of multi-volume VxFS or CFS file
systems to manage the placement of files on individual volumes in a volume set by defining
placement policies that control both initial file location and the circumstances under which
existing files are relocated
• 2K Volumes in a Volume Set — the number of volumes allowed in a volume set is now 2048,
increased from 256
• File Placement Policy Administration Improved — 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
• Load Balancing — allocation policy where the distribution of extents between volumes is
mostly equal, if none of the volumes are full or disabled
• File System Reorganization Prevention — applications that require prevention of extent and
log reorganization can disable file system reorganization using the fsadm command by
creating the /etc/fs/vxfs/vxfs_noreorg_config file (see the fsadm_vxfs(1M)
manual page)
NOTE: For more information on VxFS features that are supported with SG SMS version 2.0 for
HP-UX 11i v3 bundles, see the Veritas™ File System Release Notes HP-UX 11i v3 available on the
HP Serviceguard Storage Management Suite media and also at:
