IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
CLI and remote deployment prerequisite scanning
You can use the remote deployment prerequisite scanning feature as part of a tacmd addSystem, tacmd createnode, or tacmd updateAgent command execution when deploying an agent.
Use the command in this way to run a prerequisite check in a single command-line execution. You have the option of allowing the deployment to continue only if the check is successful, or to ignore the results and attempt the deployment even if the Prerequisite Scanner fails. The valid options are: COLLECTALL, EXECPREREQCHECK, and IGNOREPREREQCHECK. The values are to be specified in KEY=VALUE format.
The prerequisite scanning feature is available only on Tivoli Enterprise Monitoring Agents at Tivoli Monitoring V6.2.3 or later. If prerequisite scanning is enabled during a tacmd addSystem or tacmd updateAgent command execution for a target that has a Tivoli Enterprise Monitoring Agent older than V6.2.3, the command fails with an error message.
An agent-specific Prerequisite Scanner is delivered as a bundle in the IBM Tivoli Monitoring agent media. The tacmd addBundles command is used to import an agent's Prerequisite Scanner bundle into the Tivoli Enterprise Monitoring Server depot if it exists on the agent media. No additional steps must be taken beyond adding the agent bundle to the Tivoli Enterprise Monitoring Server depot as was done for remote deployment in previous releases. Next, issue a tacmd addSystem, tacmd createnode, or tacmd updateAgent command with prerequisite scanning enabled (EXECPREREQCHECK=Y). The following outcomes are possible:
- If the tacmd addSystem command runs successfully, a new application agent is installed on the endpoint and connected back. If the tacmd createnode command runs successfully, a new OS agent is installed on the endpoint and connected back. If the tacmd updateAgent command runs successfully, a new version of the agent is installed on the endpoint and connected back.
- If the prerequisite check fails, review the prerequisite check results log located on the deploying Tivoli Enterprise Monitoring Server in the CANDLEHOME/logs/checkprereq_results directory.
- The prerequisite check might fail but the installation still continues (due to the IGNOREPREREQCHECK option), and the installation fails. In this scenario, the data is received through the tacmd getdeploystatus command or the Tivoli Enterprise Portal Deploy Status workspace.
