HP Serviceguard for Linux Version A.11.19 Release Notes, July 2009

::1 localhost ipv6-localhost ipv6-loopback
For more information and recommendations about hostname resolution, see
“Configuring Name Resolution” in Chapter 5 of Managing Serviceguard.
• You must use $SGCONF/cmclnodelist, not ~/.rhosts or /etc/hosts.equiv,
to provide root access to an unconfigured node.
See “Allowing Root Access to an Unconfigured Node” in Chapter 5 of Managing
Serviceguard for more information.
• 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.
This also applies if HOSTNAME_ADDRESS_FAMILY is set to IPV6. See “About
Cross-Subnet Configurations” (page 29) for more information.
• Virtual Machines are not supported.
You cannot configure a virtual machine as either a node or a package if
HOSTNAME_ADDRESS_FAMILY is set to ANY or IPV6.
Restrictions if You Have Not Applied the July 2009 Patch
A.11.19 without the patch supports only IPv4–only and mixed-mode clusters; you
cannot configure an IPv6–only cluster.
In addition, you cannot use cmquerycl -q to configure IPv6 addresses (or hostnames
that resolve only to IPv6 addresses) for QS_HOST and QS_ADDR. You must generate
a cluster template file, edit it to set the appropriate (IPv6) values for QS_HOST and
QS_ADDR and set HOSTNAME_ADDRESS_FAMILY to ANY, and then use
cmapplyconf to apply the configuration. See the latest version of the HP Serviceguard
