Using installvcs to Perform Unattended Installations
Using installvcs with the -responsefile option is useful not only for installing and configuring VCS within a secure environment, but for conducting unattended installations to other clusters as well. Typically, you can use the response file generated during the installation of VCS on one cluster to install VCS on other clusters. You can copy the file to a system in another cluster and manually edit the file to contain appropriate values.
Assuming the systems are set up and meet the requirements for installation, you can enter the following command from one of the cluster systems where you have copied the response file. For example, if /tmp/response_file is the response file's full path name:
# cd /cdrom/cluster_server
# ./installvcs -responsefile /tmp/response_file
Syntax Used in Response File
The syntax of Perl statements included in the response file varies, depending on whether "Scalar" or "List" values are required by the variables.
For example,
$CFG{Scalar_variable}="value";
or, in the case of an integer value:
$CFG{Scalar_variable}=123;
or, in the case of a list:
$CFG(List_variable}=["value", "value", "value"];
