1 Continentalclusters for Linux Version B.01.00.00 Release Notes Announcements Continentalclusters for Linux is a Hewlett-Packard high availability solution that provides disaster recovery clustering with no distance limitation. Continentalclusters for Linux Version B.01.00.
◦ N-1 Configuration ◦ N-1 Bidirectional configuration For more details, see Understanding and Designing Serviceguard Disaster Recovery Architectures available at http://www.hp.com/go/linux-serviceguard-docs. • Continentalclusters works with any type of data replication. A set of guidelines for integrating your data replication technology can be found in the Building Disaster Recovery Serviceguard Solutions Using Continentalclusters for Linux B.01.00.00 available at http://www.hp.
◦ Console – ◦ The messages related to console notifications are written either to /dev/console or /dev/xconsole as available. OPC messages to OpenView IT/Operations – For OPC notifications, HP Operations Agent product must be installed. Continentalclusters uses the opcmsg command that is shipped as part of HP Operations Agent to send OPC notifications. Support for Serviceguard A.11.20.xx A.11.20.xx refers to Serviceguard version A.11.20.00 or A.11.20.10.
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.
Host Software Requirements • Serviceguard for Linux version A.11.20.xx • Continentalclusters requires SSH to be configured among all the nodes in the clusters. If SSH is not available on the cluster nodes, install the following RPMs on all the nodes in the clusters: ◦ openssh-4.3 or later on RHEL, and ◦ openssh-5.1 or later on SLES NOTE: SSH must not be configured to emit any banner messages on command execution.
/opt/cmcluster/doc 2. Run the following command to install Continentalclusters SNMP RPM. This RPM is required by Continentalclusters for sending SNMP notifications. For Red Hat: # rpm –i serviceguard-continentalclusters-snmpd-B.1.00.00-0.rhel5.x86_64.rpm (RHEL 5.x only) # rpm –i serviceguard-continentalclusters-snmpd-B.1.00.00-0.rhel6.x86_64.rpm (RHEL 6.x only) For SLES: # rpm –i serviceguard-continentalclusters-snmpd-B.1.00.00-0.sles11.x86_64.

Known Problems and Workarounds This section describes the known problems with the Continentalclusters for Linux version B.01.00.
But the cluster with the name exists in the configuration. • What is the workaround? This can happen when the Continentalclusters user, conclusr does not have MONITOR access in the cluster configuration. To assign a MONITOR role to conclusr, see section Setting up Security with Continentalclusters version B.01.00.00 in the Building Disaster Recovery Serviceguard Solutions Using Continentalclusters for Linux B.01.00.00 available at http:// www.hp.com/go/linux-serviceguard-docs.
