Configuring site consistency on a volume
To set the site consistency requirement when creating a volume, specify the
siteconsistent attribute to the vxassist make command, for example:
# vxassist [-g diskgroup] make volume size \
nmirror=4 siteconsistent={on|off}
By default, a volume inherits the value that is set on its disk group.
By default, creating a site-consistent volume also creates an associated version
20 DCO volume, and enables Persistent FastResync on the volume. This allows
faster recovery of the volume during the reattachment of a site.
To turn on the site consistency requirement for an existing volume, use the
following form of the vxvol command:
# vxvol [-g diskgroup] set siteconsistent=on volume
To turn off the site consistency requirement for a volume, use the following
command:
# vxvol [-g diskgroup] set siteconsistent=off volume
The siteconsistent attribute and the allsites attribute must be set to off for
RAID-5 volumes in a site-consistent disk group.
Setting the siteread policy on a volume
If the Site Awareness license is installed on all the hosts in the Remote Mirror
configuration, the disk group is configured for site consistency with several sites
enabled, and the allsites=on attribute is specified for a volume, the default read
policy is siteread.
If required, you can use the following command to set the siteread policy on a
volume:
# vxvol [-g diskgroup] rdpol siteread volume
This command has no effect if a site name has not been set for the host.
See “Changing the read policy for mirrored volumes” on page 335.
