HP Matrix Operating Environment 7.0 Recovery Management User Guide

Setting failover target type preference
During a site failover, for every logical server that has been configured with disaster protection,
Matrix recovery management activates a similarly configured peer logical server at the recovery
site. For this purpose, Matrix recovery management interacts with the Matrix OE logical server
management capability to determine a list of appropriate available targets, and chooses the most
suitable target to activate the logical server.
For a cross-technology logical server, the appropriate list of available targets may include both
physical servers and VM hosts. Matrix recovery management includes a Target type preferred
parameter in the Sites configuration tab, where you can specify the type of target preferred for
each site.
You must specify the target type preferred for all sites on the CMS at each site:
• If you specify Virtual as the target type preferred for a site, all cross technology logical servers
whose Recovery Groups prefer that site will be activated on VM hosts during an activate
operation at that site. A physical server will be chosen only if there are no VM hosts available.
• If you specify Physical as the target type preferred for a site, all cross technology logical servers
whose Recovery Groups prefer that site will be activated on physical servers during an activate
operation at that site. A VM host will be chosen only if there are no physical servers available.
By specifying appropriate target preferences for sites, you can setup a configuration where DR
Protected cross technology logical servers run on Physical servers at one site and on VM hosts at
the other site. For example, you might choose to have DR Protected cross-technology logical servers
running on physical servers at the preferred site, but running on VM hosts when they failover to
the secondary site.
