None of the bundles can be installed at the same time with or on top of stand-alone CVM (either
version 3.5 or 4.1). If CVM 3.5 (product number B9117AA) is already installed, it must be removed
before installing any of the bundles. Non-bundle installations of Serviceguard A.11.17 continue to
interoperate with stand-alone CVM 3.5 in the same way as with previous versions of Serviceguard.
Stand-alone CVM 4.1 can also be installed with non-bundle distributions of Serviceguard A.11.17
(that is, stand-alone, AR, or MCOE) and is supported without any changes to Serviceguard/CVM
capabilities (a small configuration change is required in this case, as described later in this
document).
CVM and CFS do not support rolling upgrade. But because CVM and CFS cannot be configured until
the upgrade is complete, it is possible to perform a rolling upgrade to any of the bundles as long as
all packages that use CVM are removed first and CVM is uninstalled, as described later in this
document.
Networking considerations
With CVM 3.5, only one heartbeat network (with standby LANs or Auto Port Aggregation [APA]) is
supported by Serviceguard because of restrictions in CVM 3.5. With Serviceguard A.11.17 and
CVM 4.1 (when used either only for CVM or for CVM and CFS), at least two Ethernet networks are
required. Because APA is not supported for heartbeat with CVM 4.1, one or more of these networks
must be configured as heartbeat LANs, and any remaining networks may be configured as standby
LANs. Neither Infiniband nor serial connections are supported for heartbeat with CVM. The need for
at least two networks could require modifications to the current Serviceguard network configuration,
which might require additional network hardware to be installed. The only configuration that is
supported with both CVM 3.5 and CVM 4.1 without changes is a single heartbeat network with
standby LANs.
The following table summarizes the supported heartbeat configurations for CVM 3.5 and 4.1.

The Infiniband and APA restrictions apply only to heartbeat and only with CVM. Using Infiniband,
APA, or both for data and application connectivity (and for heartbeat, when CVM is not used) is fully
supported.
HP recommends making the needed networking changes before configuring the new Serviceguard
installation. The Serviceguard cluster ASCII configuration file might need to be modified to reflect
these changes. Network configuration recommendations and configuration steps are discussed in
detail in the Managing Serviceguard Twelfth Edition manual.
