Using installvcs in a Secure Environment

In secure enterprise environments, ssh or remsh communication is not allowed between systems. In such cases, installvcs can install and configure VCS only on systems with which it can communicate (most often the local system only). When installation is complete, a "response" file is created. The Example Response File resembles the file created by installvcs. Note that a response file generated by installvcs contains descriptions and explanations of the variables and their values. By copying this file to the other systems in the cluster and editing it to reflect the current local system, you can use the installation program with the -responsefile option to install and configure VCS identically on each system without being prompted.

  To use installvcs in a secure environment

1. On one system in the cluster perform the steps listed in Starting Software Installation. In step 5, the inability to communicate between systems is detected.
     Checking system communication:
   
       Verifying communication with north .......... ping successful
       Attempting remsh with north ................ remsh successful
       Attempting rcp with north .................... rcp successful
       Checking OS version on north .................. HP-UX B.11.23
       Checking VRTSvcs package ...................... not installed
       Creating log directory on north ........................ Done
       Verifying communication with south .......... ping successful
       Attempting remsh with south ........... Cannot remsh to south
   
   CPI WARNING V-9-0-0
   slpas30 cannot communicate with or does not have remsh permissions with the following systems: south
   
   Would you like to install Cluster Server on systems north only and create a responsefile for systems south? [y,n,q] (y)
2. Enter all cluster information in the steps that follow step 5. VCS is installed and configured on systems where communication is possible. Once installation is complete, the installation program reports that the response file is stored within the file /opt/VRTS/install/logs/installvcsdate_time.response. Note that the date and time the installation began is part of the file's name.

     Note    Until VCS is installed and started on all systems in the cluster, the following appears when VCS is started: VCS:11306:Did not receive cluster membership, manual intervention may be needed for seeding

   ---

3. Using a method of your choice (for example, by using NFS, ftp, or a floppy disk), place a copy of the response file in a directory such as /tmp on the next system to install VCS.
4. On the next system, edit the response file. For the variables described in the following example, change the name of the system to reflect the current local system:
     .
     $CFG{INSTALL}{SYSTEMS} = ["south"];
     .
     .
     $CFG{KEYS}{south} = ["XXXX-XXXX-XXXX-XXXX-XXXX-XXX"];
     .

   For demo or site licenses, the license key need not be changed. When license keys are "node-locked" to specific cluster nodes, you must edit the license key.

5. On the next system, follow the steps listed in Mounting the Software Disc, but modify the command in step 2 by starting VCS installation using the -responsefile option:
     # ./installvcs -responsefile /tmp/installvcsdate_time.response
6. Repeat step 3 through step 5 until VCS has been installed on all systems in the cluster.
