Metrocluster with Continuous Access EVA P6000 for Linux Version B.01.00.00 Release Notes

Support for failover polices site_preferred and site_preferred_manual
Metrocluster for Linux supports Serviceguard failover policies: site_preferred and
site_preferred_manual. These failover policies are supported for failover packages configured in
a Metrocluster with sites defined in the Serviceguard cluster configuration file.
For more information on the site_preferred and site_preferred _manual failover polices, see Building
Disaster Recovery Serviceguard Solutions Using Metrocluster with 3PAR Remote Copy for Linux
B.01.00.00 available at http://www.hp.com/go/linux-serviceguard-docs.
NOTE: You must install the Metrocluster Add-ons for Linux RPM and Serviceguard for Linux
A.11.20.10 to use the site aware failover policies.
Support for persistent reservations
Metrocluster for Linux supports configuring persistent reservations (PR) in Metrocluster packages to
control access to LUNs. For more information on persistent reservations, see Managing HP
Serviceguard A.11.20.10 for Linux available at http://www.hp.com/go/linux-serviceguard-docs.
NOTE: The support for site_preferred and site_preferred_manual failover policies and persistent
reservations is available with Serviceguard version A.11.20.10.
Support for Device Mapper
Metrocluster for Linux supports configuring Device Mapper for disks used in Metrocluster packages.
All the Serviceguard related restrictions and guidelines for supporting DM-Multipath are also
applicable to Metrocluster configurations.
NOTE: Persistent Reservations cannot be used with Metrocluster for Linux when Device Mapper
(DM) is enabled.
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 Metrocluster nodes
Metrocluster for Linux includes support for configuring VMWare virtual machines as Metrocluster
nodes. All the Serviceguard related restrictions and guidelines for configuring VMWare virtual
machines as Serviceguard nodes are also applicable to Metrocluster configurations. In Metrocluster
configurations, Raw Device Mapping (RDM) is not supported. You must configure the 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.
