If the Detect duplicate agent registration option is selected on the management console, and then you reconfigure a managed Linux agent to add IPS over an IDS-only agent, or add IDS over an IPS-only agent, the SISFIM driver fails to load after the mandatory restart of the agent device.
Affected agent operating systems: All Linux operating systems
You can manually load the SISFIM driver after the agent restart. Use the following command to load the SISFIM driver manually:
insmod <location of sisfim.ko file>
For example, insmod /opt/Symantec/sescspagent/IDS/driver/sisfim.ko
Use the following command to verify that the SISFIM driver is loaded:
lsmod | grep sisfim
