Upgrading Worker Nodes

Server and Worker node installed on the same machine

If your installation includes a Server and Worker installed on the same machine, you should only follow Upgrading the Server and Worker node on the same machine.

Before you start

Prerequisites

Upgrade

To update the Worker Node, copy the new RPM onto the target machine and update the slchub-worker using the following DNF command: 

sudo dnf upgrade -y slchub-worker_<version>-1_x86_64.rpm
The DNF command will give feedback on the update, concluding with a Complete! message and a summary of packages that have been updated.

Use the hubctl command to start the updated Altair SLC Hub services: 

hubctl service start

If slchub-worker package was installed in a custom location or with a custom [var directory] then during upgrade the custom locations need to be specified again.

To update the Worker Node, start by copying the new RPM onto the target machine.

Updating the slchub package is done with the RPM command. Optionally specify --relocate /opt/altair/slchub=<install location> if the installation root had been changed, and --relocate /opt/altair/slchub/var=<var location> if the [var directory] location had been changed. 

sudo rpm -U slchub-worker_<version>-1_x86_64.rpm

To update the Worker Node, copy the new MSI to the target machine. Launch the MSI and replace the existing slchub-worker installation.

Use the hubctl command to start the updated Hub services: 

hubctl service start

Verification
