The following example shows how to check if the relevant processes aksusbd and hasplmd are active:

...

...

...

$ ps -ef | grep -i aksusb

...

root 728 1 0 13:08 ? 00:00:00 /usr/sbin/aksusbd

...

$ ps -ef | grep -i hasplmd

...

root 740 1 0 13:08 ? 00:00:00 /usr/sbin/hasplmd -s

You can also check the status of the services using the systemctl command. Please note that in the current versions of the license drivers, there are two services. Older versions only used one systemd service (aksusbd).

# systemctl status aksusbd
# systemctl status hasplmd

If you do not see the two processes in the output, the license drivers are not in the correct state. Please restart them as described below.

Linux Tasks

Current Versions

The current versions of the runtime drivers use two systemd services: aksusbd.service and hasplmd.service.

You can start, stop, and restart the service.

Starting and stopping the services (as the root user:

• The two services have a dependency such that starting one of them will start the other, stopping one of them will stop the other, and restarting one of them will restart the other.
  
  
• Starting the services:
  # systemctl start aksusbd
  # systemctl start hasplmd
  
  
• Stopping the services:
  # systemctl stop aksusbd
  # systemctl stop hasplmd

Older Versions

The script to start and stop the license drivers is /etc/init.d/aksusbd.

If you need to start the license drivers, execute the following command as the root user:

If you need to restart the Sentinel license drivers, perform the following steps:

Important: any running emulators will be stopped if the license service is forced to stop despite existing service dependencies (i.e., running emulators). So any running guest systems must be cleanly shutdown before restarting the license service in order to avoid data loss.
