In theServiceguard with IntegrityVM environment, you can usethe following network configurations:
— Heartbeat LAN
Serviceguard nodes useheartbeat LANs to maintain communicationwith one another.Whether
Serviceguard is installed on the VM Host system or on the guest, HP recommends that you
configure every LAN as a heartbeat LAN.
— Primary and standby LANs
For local LAN failover, a Serviceguard node must have both a primary and standby LAN. In
both Serviceguard in Guest and Serviceguard in Host configurations, use vswitches or hubs to
connect two pNICs to the same network broadcast domain.
For Serviceguard in Host configurations, Serviceguard monitors the physical connections and
the vswitch monitor moves the vswitch between pNICs automatically.
In a Serviceguard in Guest configuration, the pNICs are connected to vswitches, which are
configured as vNICs in the guest. In this configuration, Serviceguard running in the guest
determines the primary and standby LANs and performs the failover in the guest.
— Autoport Aggregation (APA)
You can use HP-UX APA in the Serviceguard configuration on the VM Host systems. Use APA
in MANUAL or AUTO-FEC modes when running on the VM Host system. Do not use
LACP_AUTO mode link aggregates. For more information about APA, see the HP Auto Port
Aggregation (APA) Support Guide.
— Virtual LANs (VLANs)
VLANs can be configured on the vswitches or the physical switches. You can use VLANs on
the VM Host system (as described in the Using HP-UX VLANS manual). You can configure the
VLAN on vswitches used by guests (as described in “Configuring VLANs” (page 94)).
The following sections describe the configuration procedures and the specific requirements for each of
the Serviceguard configurations.
10.2 Serviceguard in Guest Configurations
You can install Serviceguard on an HP-UX guest to provide high availability for the applications running
on the guest. In this type of configuration, the guest is configured as a node in a Serviceguard cluster.
Depending on the configuration of the cluster, the application package can fail over from one guest to
another guest in the same VM Host system, from one guest to another guest in a VM Host system, or from
the guest on a VM Host system to a separate physical server or nPar. You can even mix and match
Serviceguard in Guest configurations to meet your specific requirements. The following sections describe
the Serviceguard in Guest configurations.
10.2.1 Cluster in a Box
Figure 10-1 shows the configuration of an application package that can fail over to another guest on the
same VM Host system.
