Running the IBM License Metric Tool(ILMT) disconnected scans

Disconnected scans allow for discovering software and hardware inventory on computers that do not have connection to the BigFix server. Scripts that are provided in the disconnected scanner package initiate software and capacity scans, and create a package with scan results that you later upload to IBM License Metric Tool.

  1. Preparing the disconnected scanner package for the Linux on IBM Z, extract the file into a directory, e.g., /root/LMT. For further information, please refer to Downloading the disconnected scanner package.

  2. Before running the scanner, please make sure the Access global performance data option has been turned on from the Linux on IBM Z HMC, you can navigate to Partition Details-->Controls->Access global performance data to check its value.

  3. Installing the disconnected scanner and gathering initial data:

    [root@computenode1 LMT]# ./setup.sh

Note: z/VM® compute nodes need special environment viarable when license model is engine. The environment variable will be set while adding host. If the environment variable is not configured due to some reason, following command can be used to correct this issue:

[root@mgmtnode]#icic-config compute license --fix
Node BOEIAAS4
Environment variable is configured successfully!
Node BOEIAAS3
Environment variable is configured successfully!
