Remove SLC

Before you start

Goal

  • Updated Altair SLC Hub configuration for removed Altair SLC installation.

Prerequisites

  • A configured Hub server.
  • A configured worker node.
  • Altair SLC Hub configuration privileges for the server host and worker node.

Removing Altair SLC

Remove Altair SLC in the normal way from the worker node.

Update Altair SLC Hub configuration

When an Altair SLC installation has been removed from a worker node, it should then be removed from the list of Altair SLC installations for the Altair SLC Hub worker. To do this run the following command: 

hubctl slcinstall rm /opt/altair/slc/2023

The /opt/altair/slc/2023 path might need to be replaced with the installation path for the version of Altair SLC to remove.

At this point, you may wish to add tags to a different Altair SLC installation for the Altair SLC Hub worker. For example, if the Altair SLC instance removed from /opt/altair/slc/2023 was tagged as default and there is another installation at /opt/altair/slc/2024, you may wish to tag the /opt/altair/slc/2024 Altair SLC instance as default. To do this run the following command: 

hubctl slcinstall addtag /opt/altair/slc/2024 default

The /opt/altair/slc/2024 path might need to be replaced with the location of your remaining Altair SLC installation.

When an Altair SLC installation has been removed from a worker node, it should then be removed from the list of Altair SLC installations for the Altair SLC Hub worker. To do this run the following command: 

hubctl slcinstall rm "C:\Program Files\Altair\SLC\2023"

The C:\Program Files\Altair\SLC\2023 path might need to be replaced with the installation path for the version of Altair SLC to remove.

At this point, you may wish to add tags to a different Altair SLC installation for the Altair SLC Hub worker. For example, if the Altair SLC instance removed from C:\Program Files\Altair\SLC\2023 was tagged as default and there is another installation at C:\Program Files\Altair\SLC\2024, you may wish to tag the C:\Program Files\Altair\SLC\2024 Altair SLC instance as default. To do this run the following command: 

hubctl slcinstall addtag "C:\Program Files\Altair\SLC\2024" default

The C:\Program Files\Altair\SLC\2024 path might need to be replaced with the location of your remaining Altair SLC installation.

Update execution profiles

Having removed an Altair SLC installation, it is likely that some tags have been removed and/or updated. If you have set up execution profiles to reference specific Altair SLC version tags, you will need to update the execution profiles, otherwise Altair SLC Hub workloads may fail to run. For more information on execution profiles, see Execution Profiles.

Verification

Verify Altair SLC installations

  • run the hubctl verify slc command
  • run the hubctl slcinstall list command

To verify Altair SLC registration settings, use the command: 

hubctl verify slc

To list the registered Altair SLC installations and view their associated version tags, use the command: 

hubctl slcinstall list
