About Remote Mirror solutions
The Remote Mirror feature of the Storage Foundation software mirrors volumes
at separate sites, which allows applications to be recovered at an alternate site in
case of site failure. An enterprise can thus continue to function despite the loss
of one site. This feature supports both non-ISP and ISP volumes. The solution
presented below is intended to highlight how to implement the remote mirrors
for ISP volumes.
Further information on the Remote Mirror feature including recovery procedures
can be found in the Veritas Volume Manager Administrator’s Guide.
Note: The Remote Mirror feature requires that the Site Awareness license has
been installed on all hosts at all sites that are participating in the configuration.
About Remote Mirror configurations
In a Remote Mirror configuration the hosts and storage of a cluster that would
usually be located in one place, are instead divided between two or more sites.
These sites are typically connected via a redundant high-capacity network that
provides access to storage and private link communication between the cluster
nodes.
Figure 5-1 illustrates a typical two-site remote mirror configuration.
