Continentalclusters for Linux Version B.12.00.00 Release Notes

Support for IPv6 protocol
Primary and recovery clusters in Continentalclusters can be configured with IPv6 address.
Additionally, notifications provided for cluster events can use an IPv6 address.
IMPORTANT: A mixed cluster configuration, in which one cluster is configured with the IPv4
protocol, and the other cluster with the IPv6 protocol, is not supported.
Support for Device Mapper multipathing (DM-Multipath)
Metrocluster for Linux supports configuring Device Mapper multipathing (DM-Multipath) for disks
used in Continentalclusters packages. All Serviceguard related restrictions and guidelines for
supporting DM-Multipath are also applicable for Continentalclusters configurations.
For more information on the restrictions, see the HP Serviceguard for Linux Certification Matrix
available at http://www.hp.com/go/linux-serviceguard-docs.
Support for VMWare virtual machines as Continentalclusters nodes
Continentalclusters for Linux includes support for configuring VMWare virtual machines as
Continentalclusters nodes. All Serviceguard related restrictions and guidelines for configuring
VMWare virtual machines as Continentalclusters nodes are also applicable for Continentalclusters
configurations.
In Continentalclusters configurations using pre-integrated data replication solution using HP 3PAR
Remote Copy, HP Storage Continuous Access P9000/XP, and Continuous Access EVA, you must
configure Fiber channel N-Port ID Virtualization (NPIV) for all the virtual machines. For more
information on configuring NPIV, see Using HP Serviceguard for Linux with VMware virtual machines
whitepaper available at http://www.hp.com/go/linux-serviceguard-docs.
