HP Serviceguard Version A.11.19 Release Notes, July 2009

Table Of Contents
NOTE: This also applies if HOSTNAME_ADDRESS_FAMILY is set to ANY. See
Allowing Root Access to an Unconfigured Node” in Chapter 5 of Managing
Serviceguard for more information.
If you use a Quorum Server, you must make sure that the Quorum Server hostname
(and the alternate Quorum Server address specified by QS_ADDR, if any) resolve
to IPv6 addresses.
IMPORTANT: You must use Quorum Server version A.04.00 or later. See the latest
Quorum Server release notes for more information; you can find them at
docs.hp.com under High Availability > Quorum Server.
The Quorum Server itself can be an IPv6–only system; in that case it can serve
IPv6–only and mixed-mode clusters, but not IPv4–only clusters.
If you use a Quorum Server, and the Quorum Server is on a different subnet from
cluster, you must use an IPv6-capable router.
Hostname aliases are not supported for IPv6 addresses, because of operating
system limitations.
NOTE: This applies to all IPv6 addresses, whether
HOSTNAME_ADDRESS_FAMILY is set to IPV6 or ANY.
Cross-subnet configurations are not supported in IPv6-only mode.
NOTE: This also applies if HOSTNAME_ADDRESS_FAMILY is set to ANY. See
About Cross-Subnet Configurations” (page 37) for information about this type
of configuration.
CFS, CVM, VxVM, and VxFS are not supported in IPv6–only mode.
NOTE: CFS and CVM should not be installed on any system in an IPv6–only
cluster, even if they are not configured.
This also means that the Serviceguard component of bundles that include
Serviceguard cannot be configured in IPv6 mode.
HPVM is not supported in IPv6-only mode. You cannot configure a virtual machine
either as a node or a package in an IPv6-only cluster.
Serviceguard Manager does not yet support IPv6-only mode; see “Current
Limitations of Serviceguard Manager (page 33).
