Veritas Volume Manager 5.0 Release Notes HP-UX 11i v3 (5992-1952, August 2011)

• Recommendation for Config Backup and Restore
The Config Backup and Restore (CBR) feature of VxVM allows the disk group configuration
to be backed up and restored if configuration information is lost or corrupted.
The backup directory should be large enough to accommodate copies of all the disk groups
present at any given point in time. With Veritas Volume Manager 5.0, it is recommended that
the backup directory be a minimum of “m x (n+1) MB”, where m is the private region size
and n is the number of disk groups. The default private region size is 32 MB. The extra storage
space is required to hold the temporary copy of the disk group configuration when a disk
group import or configuration change occurs.
The default backup directory is /etc/vx/cbr/bk. The location of the backup directory can
also be configured using the following command:
# vxconfigbackup -l backup_directory_path
• 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
