66 Installing and configuring the VCS One client
Deciding about a credential installation
Right before the installation
Right before you install the VCS One client, do the following:
■
Set up ssh or rsh communications.
■ You must have ssh communications from the system where you run the
installation to the systems where you are installing the VCS One client
software.
■ Ensure that the specific ports needed for installing the VCS One client
are enabled. See “
Opening the required ports ” on page 21.
■ The ssh communication must be present on the system where the
installation is run and the Policy Master cluster systems.
See “ Setting up the Policy Master cluster hardware ” on page 20.
■ Make sure that the clock times for Policy Master systems in the same time
zone are within 30 minutes of one another or the installation may fail.
■ Make sure the Policy Master is running. On a Policy Master system, enter
the following:
#
haadmin -state
See “ Verifying the Policy Master installation ” on page 55.
■ Choose the appropriate installation software disc. Installation software
discs are provided for each platform type.
■
Mount the software disc on the system where you plan to run the
installation.
■
Have the VCS One Policy Master virtual IP address ready. Communication
must be enabled between the installer and the system with the Policy
Master virtual IP address.
Deciding about a credential installation
Installing the VCS One client using credentials is optional. However, if you
install the client without credentials, you must establish paswordless ssh
communication between the client and the active Policy Master system.
For more information on setting up ssh communication, see “ Configuring ssh,
rsh, or remsh before installing .”
For a credential deployment, you have the following options:
■ Install the client using a deployment credential. If you do not establish ssh
communications with the active Policy Master system, you must have a copy
of the deployment credential on the system from which you run the
installer.
See “ Installing the client using a deployment credential ” on page 67.
