HP Integrity Virtual Machines Installation, Configuration, and Administration Version A.03.50

11 Using HP Serviceguard with Integrity VM
After you have installed Integrity VM and created the guest, you can install Serviceguard on
either the VM Host system (to provide failover for the guest), or on the guest (to provide failover
for applications running on the guest). This chapter describes how to configure Serviceguard
with Integrity VM, including the following topics:
• Section 11.1: “Introduction to HP Serviceguard with Integrity VM” (page 153)
• Section 11.2: “VMs as Serviceguard Nodes Configurations” (page 154)
• Section 11.3: “Serviceguard in VM Host Configuration” (page 157)
• Section 11.4: “Upgrading from the Integrity VM A.01.20 Toolkit” (page 163)
• Section 11.5: “Troubleshooting Serviceguard with Integrity VM” (page 165)
This chapter assumes you are familiar with HP Serviceguard. The procedures in this chapter use
the HP Serviceguard commands to accomplish Serviceguard tasks. You can use Serviceguard
Manager instead. For more information, see the Managing Serviceguard manual.
11.1 Introduction to HP Serviceguard with Integrity VM
After you set up Integrity VM, you can install HP Serviceguard on either the VM Host or on the
HP-UX guest. Do not use Serviceguard on both the VM Host and the guest at the same time. The
following Serviceguard versions are supported on the VM Host and on the guests:
Table 11-1 Serviceguard Version Support
NotesSupported OnServiceguard Version
VM Host or HP-UX GuestA.11.16
VM Host or HP-UX GuestA.11.17
Requires HP-UX 11i V3HP-UX GuestA.11.18
The Serviceguard version must be appropriate to the version of HP-UX. For more information,
see the Managing Serviceguard manual.
• To protect guest applications, install Serviceguard on the HP-UX guest. Applications on a
guest can fail over to any of the following:
— Another guest configured as a Serviceguard node that is running on the same VM Host
system (see Section 11.2.1: “Cluster in a Box” (page 155))
— Another guest configured as a Serviceguard node running on a different VM Host
system (see Section 11.2.2: “Virtual-to-Virtual Cluster” (page 155))
— Another server or partition that is not running Integrity VM (see Section 11.2.3:
“Virtual-to-Physical Cluster” (page 156))
Windows guests do not support HP Serviceguard; therefore, Windows guest applications
cannot be configured as Serviceguard packages.
• To protect guests, install HP Serviceguard on the VM Host system. Guests configured as
Serviceguard packages (distributed guests) are subsequently managed using HP Serviceguard
commands. If the VM Host system fails, the distributed guest automatically fails over to
another node in the Integrity VM multiserver environment. Integrity VM guests which can
relocated between Integrity VM Hosts are configured into an Integrity VM multiserver
environment that contains the same set of servers as is in the Serviceguard cluster. (For more
information, see Section 11.3 (page 157)). Guests of any operating system (HP-UX and
Windows) can be configured as Serviceguard packages.
Each Serviceguard configuration provides a level of protection against failure. Choose the
configuration that best meets your needs, keeping the following requirements in mind:
