6.4.1 Installing HP Serviceguard for Linux using cmeasyinstall
The cmeasyinstall tool helps you to install HP Serviceguard for Linux and its components, such
as Serviceguard Manager, Toolkits, Extended Distance Cluster and Metrocluster except for SGeSAP.
You can also execute the cmeasyinstall tool from one of the nodes in the specified list and
has a capability to do a fresh installation on the remote nodes that are specified. It also provides
an option to install the software prerequisite along with HP Serviceguard for Linux and its
components.
Prerequisites
Before you begin to use cmeasyinstall tool, ensure that the following prerequisites are met:
• You must be a root user.
• You must have execute permission on the node specified.
• All nodes must be reachable using FQDN (Fully Qualified Domain Name) or PQDN
(Partially Qualified Domain Name).
• Ensure that all the nodes specified with cmeasyinstall are at same major version of the
operating system.
• Ensure that PERL is installed on all the systems where you intend to install Serviceguard using
the cmeasyinstall tool.
• Ensure that YUM (Yellowdog Updater Modified) update service on Red Hat Enterprise Linux
Server or Zypper on SUSE Linux Enterprise Server is configured if you intend to use the -a
option.
NOTE: The cmeasyinstall tool does not install HP Serviceguard Extension for SAP (SGeSAP)
A.06.00.20 automatically from the ISO or DVD. You must install SGeSAP manually using rpm
-ivh command. If you are already running SGeSAP A.06.00.20, then it is not required to install
the product.
Also, the cmeasyinstall tool does not install Quorum Server.
The cmeasyinstall tool has the following advantages:
• Checks for dependencies and prompts you to install the required software or packages, if not
already installed.
• Streamlines the installation of the several rpm packages that are included on the DVD or ISO
image.
• Reduces the installation from many commands to one command to invoke the tool.
• Takes the list of nodes that are expected to be part of the cluster and installs the software on
all the nodes.
The cmeasyinstall tool prompts for the directory path where the HP Serviceguard for Linux
DVD or ISO image is mounted. It checks for Linux packages that are required as prerequisites for
HP Serviceguard for Linux and its components. For more information about software prerequisites,
