Site-based allocation of storage to volumes
Examples of storage allocation using sites
The examples in the following table demonstrate how to use site names with the
vxassist command to allocate storage. The disk group, ccdg, has been enabled
for site consistency with disks configured at two sites, site1 and site2.
Command Description
# vxassist -g ccdg make vol 2g \
nmirror=2
Create a volume with one mirror at each
site. The value of nmirror must be greater
than or equal to the number of sites unless
allsites is set to off.
# vxassist -g ccdg -o ordered \
make vol 2g \
layout=mirror-stripe ncol=3 \
ccdg01 ccdg02 ccdg03 ccdg09 \
ccdg10 ccdg11
Create a mirrored-stripe volume specifying
allocation order to validate redundancy
across the sites. The named disks must be
tagged with the appropriate site name, and
there must be sufficient disks at each site to
create the volume.
# vxassist -g ccdg make vol 2g \
nmirror=2 mirror=site \
site:site1 site:site2
Create a volume with one mirror at each of
the named sites. All sites must be named
and the value of nmirror must be greater
than or equal to the number of sites unless
allsites is set to off.
# vxassist -g ccdg make vol 2g \
nmirror=2 ccdg01 ccdg09
Create a volume with one mirror on each of
the named disks. The named disks must be
tagged with the appropriate site name, and
there must be sufficient disks at each site to
create the volume.
# vxassist -g ccdg make vol 2g \
nmirror=2 siteconsistent=off \
allsites=off
Create a mirrored volume that is not site
consistent. Both mirrors can be allocated
from any available storage in the disk
group.
# vxassist -g ccdg make vol 2g \
nmirror=2 site:site2 \
siteconsistent=off \
allsites=off
Create a mirrored volume that is not site
consistent. Both mirrors are allocated from
any available storage in the disk group that
is tagged as belonging to site2.
# vxassist -g ccdg make vol 2g \
nmirror=2 !site:site1 \
siteconsistent=off \
allsites=off
Create a mirrored volume that is not site
consistent. Both mirrors are allocated from
any available storage in the disk group that
is tagged as not belonging to site1.
# vxassist -g ccdg mirror vol \
site:site1
Add a mirror at a specified site. The
command fails if there is insufficient
storage available at the site.
