Backup and Restore of HACMP Cluster 5
Networks: As an independent, layered component of AIX, the HACMP software
is designed to work with any TCP/IP-based network. Nodes in an HACMP cluster
use the network to:
- Allow clients to access the cluster nodes
- Enable cluster nodes to exchange heartbeat messages
- Serialize access to data (in concurrent access environments).
Types of Networks: The HACMP software defines two types of communication
networks, characterized by whether these networks use communication interfaces
based on the TCP/IP subsystem (TCP/IP-based) or communication devices based
on non-TCP/IP subsystems (device-based).
Clients: A client is a processor that can access the nodes in a cluster over a local
area network. Clients each run a "front end" or client application that queries the
server application running on the cluster node.
The entire cluster is accessed via a cluster host name which is referred as a
Virtual Environment Domain Name, which represents the complete HACMP
cluster over the network.
3. Installing Data Protector Agents in a HACMP Cluster
To back up an Informix Database running in a virtual environment in a HACMP
Cluster, Data Protector has to be installed on all the cluster nodes. The virtual
environment FQDN / virtual environment package IP address has to be imported
to the Data Protector cell.
Following are the steps that need to be executed in order to install Data Protector
in a HACMP Cluster:
Note: You must have root permissions on every target system.
3.1. Local Installation
In case there is no Unix Installation Server in the Data Protector cell, the Data
Protector Agent(s) need to be installed locally on all the nodes. Follow the
procedure below to install the agents locally:
1. Insert any HP-UX Installation Server installation CD-ROM.
2. From the <Mount_Point>/LOCAL_INSTALL directory run omnisetup.sh
command. The syntax of the command is as follows:
omnisetup.sh [-source <directory>] [-server <name>] [-install
<component_list>] where:
