packages running. The packages are no longer monitored by Serviceguard, but the applications
continue to run. Packages in this state are called detached packages. When you have done the
necessary maintenance, you can restart the node or cluster, and normal monitoring will resume
on the packages. For more information on the LAD feature, see “Managing Serviceguard A.11.20”

HP vPars and HP Integrity VM
Configuring virtual machine using HP Integrity Virtual Machines (VM) or HP-UX Virtual Partitions
(vPars 6) as a package (also for as a node) in Metrocluster or Continentalclusters provides remote
data protection of applications running inside the virtual machine. In addition, it simplifies the
geographical movement of the virtual machine from one site to another in case of site outages and
it ensures high availability of the virtual machine within the site.
Configuring virtual machine Integrity VM or vPars 6 as a node in Metrocluster or Continentalclusters
will help in reducing the startup of applications configured within the VM guest OS and provides
remote data protection of applications running inside the virtual machine. It also helps in
consolidation of physical hosts.
Both these configurations protect the VM environment from disasters that result in the failure of an
entire data center. For more information on the configuration, see the white paper “Implementing
disaster recovery in virtualized environment using HP vPars and HP Integrity VM with Metrocluster
and Continentalclusters on HP-UX 11i available at http://www.hp.com/go/hpux-serviceguard-docs
