Continentalclusters for Linux Version B.01.00.00 Release Notes

When using any of the pre-integrated physical replication such as Continuous Access XP, Continuous
Access EVA or 3PAR Remote Copy modular packages configured as primary or recovery packages
must include the appropriate replication specific module for the Continentalclusters for Linux
environment.
For more information on configuring modular packages in Continentalclusters, see Building Disaster
Recovery Serviceguard Solutions Using Continentalclusters for Linux B.01.00.00 available at
http://www.hp.com/go/linux-serviceguard-docs.
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.
There is no support for VMWare virtual machines as Continentalclusters nodes when using
pre-integrated data replication solution using 3PAR Remote Copy for Linux.
In Continentalclusters configurations using pre-integrated data replication solution using 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.
