Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

Site-based allocation of storage to volumes
The vxassist command can be used to create volumes only from storage that
exists at a specified site, as shown in this example:
# vxassist -g diskgroup make volume size site:site1 \
[allsites={on|off}] [siteconsistent={on|off}]
The storage class site is used in similar way to other storage classes with the
vxassist command, such as enclr, ctlr and disk.
See “Mirroring across targets, controllers or enclosures” on page 296.
If the Site Awareness license is installed on all the hosts in the Remote Mirror
configuration, and site consistency is enabled on a volume, the vxassist command
attempts to allocate storage across the sites that are registered to a disk group.
If not enough storage is available at all sites, the command fails unless you also
specify the allsites=off attribute.
By default, the allsites attribute is set to on for volume in a site-consistent disk
group. The allsites and siteconsistent attributes must be set to off for RAID-5
volumes in a site-consistent disk group.
In a similar way to mirroring across controllers, you can also ensure that plexes
are created at all sites that are registered for a disk group:
# vxassist -g diskgroup make volume size mirror=site
The allsites and siteconsistent attributes can be combined to create a
non-site-consistent mirrored volume with plexes only at some of the sites:
# vxassist -g diskgroup make volume size mirror=site \
site:site1 site:site2 ... allsites=off siteconsistent=off
a non-site-consistent mirrored volume with plexes at all of the sites:
# vxassist -g diskgroup make volume size mirror=site \
allsites=on siteconsistent=off
a site-consistent mirrored volume with plexes only at some of the sites:
# vxassist -g diskgroup make volume size mirror=site \
site:site1 site:site2 ... allsites=off siteconsistent=on
or a site-consistent mirrored volume with plexes at all of the sites:
# vxassist -g diskgroup make volume size mirror=site \
allsites=on siteconsistent=on
