Veritas Storage Foundation for Oracle 5.0 Administrator's Guide, HP-UX 11i v3, Second Edition, December 2008

To add a volume to a volume set
◆
Use the vxvset command as follows:
# /usr/sbin/vxvset [-g diskgroup] [-f] addvol volset \
volume
Warning: The -f (force) option must be specified if the volume being added,
or any volume in the volume set, is either a snapshot or the parent of a
snapshot. Using this option can potentially cause inconsistencies in a snapshot
hierarchy if any of the volumes involved in the operation is already in a
snapshot chain.
See the Veritas Volume Manager Administrator's Guide.
For example, to add the volume db02, to the volume set db01vset, use the following
command:
# /usr/sbin/vxvset -g PRODdg addvol db01vset db02
File system creation guidelines
Follow these guidelines when creating VxFS file systems:
■ Specify the maximum log size when creating file systems for databases.
■ Except for specifying the maximum log size and support for large files as
required, use the VxFS defaults when creating file systems for databases.
■ Never disable the intent logging feature of the file system.
■ For redo logs, create a single file system using a simple (and mirrored, if
necessary) volume. Put the other tablespaces and database files on separate
file systems created on striped, striped and mirrored, or RAID-5 volumes.
■ When using the command line, use the mount points to name the underlying
volumes. For example, if a file system named /db01 is to be created on a
mirrored volume, name the volume db01 and the mirrors db01-01 and db01-02
to relate to the configuration objects. If you are using the vxassist command
or the GUI, this is transparent.
■ If Quick I/O is supported, select vxfs as the file system type to take advantage
of the Quick I/O feature, online administration, fast recovery of the VxFS file
system, and superior reliability features.
Choose a file system block size that matches or is a multiple of the block size of
your Oracle database (db_block_size).
