Implementing disaster recovery for HP Integrity Virtual Machines with Metrocluster and Continentalclusters on HP-UX 11i

Metrocluster/Serviceguard can monitor only the status of the VM guest running as a Serviceguard
packagenot the applications running within the VM. To monitor the applications running within a
VM, custom application monitoring can be implemented in one of the following ways:
Guest-based monitoring: A program or agent runs within the VM and monitors the status of the
application running within the same VM. Apart from monitoring whether the application is running
fine, the monitoring program can also undertake some recovery actions in case there is any
problem with the application.
Host-based monitoring: In this method, a service defined within the Serviceguard VM guest
package can be used to monitor an application running within the VM. It can do so by interacting
either with the application directly or with a customized monitoring program running within the VM
guest.

Configuring Integrity Virtual Machines as packages in
HP Continentalclusters
Overview
HP Continentalclusters supports the deployment of HP Integrity VM guests as packages. The following
provides an overview of the supported configuration types, types of backing stores, supported array-
based physical replication, and online virtual machine migration feature of HP VM.
In Continentalclusters, HP VM guests can be configured as packages for disaster recovery.
HP VM packages in Continentalclusters are supported in both bi-directional Continentalclusters
configuration and N-1 Continentalclusters configuration.
The following array-based physical replication solutions are supported:
HP Metrocluster with Continuous Access XP/P9000
HP Metrocluster with Continuous Access EVA
HP Metrocluster with EMC SRDF
The following backing stores are supported while configuring HP VM guests in Continentalclusters:
LVM
VXVM
SLVM
CVM/CFS
Whole disks
Notes:
1. CVM/CFS will be supported as a backing store only when configured with SADTA.
2. When a whole disk is used as a backing store, only modular HP VM packages are supported in Continentalclusters.
In Continentalclusters, the backing stores will be replicated using supported physical data replication
solutions or using data sender/data receiver packages. There are two approaches to replicating
backing stores:
1. All the backing stores used by the guest are replicated.
