Enable multiple license server hosts

Configuring multiple license server hosts is optional. It provides a way to keep LSF running if a license server host goes down.

Distributing licenses over multiple server hosts provides a fallback, in case your license server daemons fail.

With this method, you run multiple license server daemons, each with its own license file. Each license file has a SERVER line keyed to the license server host it is assigned to. The cluster is partially licensed as long as any one license server daemon is running, and fully licensed when all license server daemons are running. When a license server host is unavailable, the licenses managed by that host are unavailable. You decide how many LSF licenses to put on each license server host.

  1. Obtain multiple license files, with your total number of licenses divided appropriately among the license server hosts. Provide the following information for each license server host:
    • Host name and FlexNet host ID

    • The products and number of licenses you want to be managed by this host

  2. Specify the location of all the licenses in LSF_LICENSE_FILE, not just one.

    Use a use a pipe (|) to separate the port@host_names distributed license servers on UNIX, Linux and Windows. List the primary license server host first (the one you want LSF to contact first)

  3. Start lmgrd on all license server hosts.
  4. To allow the new permanent licenses to take effect, reconfigure the cluster with the commands:

    lsadmin reconfig

    badmin mbdrestart
