• “Installing and configuring the cluster software” (page 25)
Checking the IP network setup and SAN configuration
RHCS and SLE HA require that a single IP subnet be dispersed over all sites in a disaster-tolerant
cluster setup. This enables all nodes in a cluster to exchange heartbeat (alive) messages.
Several VLAN technologies that can extend single subnets over long-distance connections are
available. For information about latency and distance support, see your Linux cluster software
documentation.
Configuring native multipath software
For information about installing and configuring the Multi-path Device Mapper for Linux Software,
see the Multi-path Device Mapper for Linux Software application and release notes. You can find
these documents on the Manuals page of the HP Business Support Center website: http://
www.hp.com/ support/manuals. In the Storage Software section, click Multi-path Device Mapper
for Linux Software.
To use an HBA driver's native multipath failover, follow the instructions in the documentation
provided by the manufacturer.
Load balancing affects multipath performance. To ensure optimal load balancing, see the installation
and configuration procedures in your multipath software documentation.
NOTE:
• For a list of supported multipath software, see the HP 3PAR array information on the HP SPOCK
website: http://www.hp.com/storage/spock.
• For more information on native device mapper, see HP 3PAR implementation guide for RHEL
and SUSE operating systems.
Configuring the HP 3PAR storage system
For detailed information on configuring the HP 3PAR storage system, see the 3PAR Management
Console User Guide or the 3PAR CLI Administrator’s Manual. You can also consult your HP service
representative for further assistance, including help with creating a geographically dispersed cluster
environment.
Creating hosts and setting host persona
Before you can assign disk storage to a cluster node, you must create a host entry for the locally
connected server/node on each HP 3PAR storage system. Each HP 3PAR storage system port
