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.
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. A typical two-site remote mirror configuration is illustrated in Figure 5-
