    Repare Broken RSCD Agent with Unified Install

      Hello,

      I have some broken RSCD agents in my infrastructure and I would like to use the unified installer to remove and install the same version of the RSCD agent. I cannot use standard upgrade job as the agent is not responding to BBSA.

       

      I noticed the "AgentInstallerScript.sh" created by the unified installer have some preinstall steps to check if there is already an RSCD agent installed. and there is an exit when a previous installation is detected.

       

      I would like to customize this script to permit a RE-Installation on an existing agent or a remove of the agent before the new installation.

       

      Can you tell me where this script is located ?

       

      Thanks  in advance.

      Eric

          this script is created on the fly, i don't think there is a way to change what it runs.

            In your opinion, do you think I can propose a RFE to ask the implementation of flag or a modification of these scripts to permit a forced BSA Agent installation.

              Bill,

              Any chance you know where these script snippets live? You mention it is "created on the fly" but where is it created from? IMO allowing users to slip in their custom code here would be immensely helpful.

               

              cat AgentInstallerScript.sh

              #!/bin/sh

              #

              # This shell script was generated by the BMC BladeLogic Server Automation Console.

              echo "Installation of the agent is starting."

               

              #

                probably in a jar in NSH/br/stdlib or in NSH/share somewhere.

                 

                 

                i've got to say it's not supported to go messing w/ these and they'll be wiped on upgrades.

                 

                 

                if you open a ticket and we find out it's because of some tinkering here, i'll call and yell at you that you shouldn't have messed around w/ it

                  Guys like me, keep guys like you in business

                  I think this is all about timing... If I can find a way to kick off the agent install job, and pause the job before it copies AgentInstallerScript.sh to the target, I can have another job go and update it. Kyle Sorg & I are stressing the limits of BSA every day, this is just a sampling... hahaha
