Issue/Introduction

• Restarting a GA_DaemonDriver using dmctl or from Command Line Interface (CLI).
• Check the status of the Event-Driver in Smarts SAM for an underlying domain.
• Check that the NL Driver is started and restart it if necessary.
• How to reconfigure Smarts SAM in different ways i.e restarting the hypernotif driver and NL driver.
• Stale notifications are not being cleared in the Smarts SAM Notification Log Console.

Environment

Smarts - 10.1.x

Cause

Restarting the Event Driver, Smarts SAM domain should re-synchronize all the CLEAR events that were missed during disconnect with underlying domain.

Resolution

1. Find the exact name of the GA_DaemonDriver that you would like to restart. You can do so by running the following dmctl getInstance (geti) command as follows:
   
   

   ./dmctl -s <SAM_Domain> geti GA_DaemonDriver

   ICS-Business-Impact-Driver       ICS-Group-Driver
   ICS-Impact-Driver                ICS-MaintenanceHandler-Driver
   OTM-SONET-Driver                 IC-ACM_Event-Driver
   IC-AM_Topo-Driver                INCHARGE-AM-PM_Event-Driver
   INCHARGE-AM-PM_Topo-Driver       INCHARGE-OI_DomainProxy-Driver
   INCHARGE-OI_NL-Driver            INCHARGE-OI_Topo-Driver
   
    
2. To determine if the driver is running, run the following command:
   

   ./dmctl -s <SAM_Domain> get GA_DaemonDriver::INCHARGE-AM-PM_Event-Driver::isRunning
   or
   ./dmctl -s <SAM_Domain> get GA_DaemonDriver::INCHARGE-AM-PM_Event-Driver::state

   A command output of TRUE/GA_DRIVER_RUNNING means the driver is running, and FALSE/GA_DRIVER_STOPPED means it is not running.
   
    
3. Run a dmctl getOperation (getOper) command against the GA_DaemonDriver class as follows: 
   

   ./dmctl -s <SAM_Domain> getoper GA_DaemonDriver

   The output of the getOper command will be a list of the operations that can be executed against the members of that class:
   
   Operations for class GA_DaemonDriver:
       <object> clone <string>clone_name
       <void> clearVariables
       <void> setVariable <string>varName <string>varValue
       <object> getMyParameters <string>mode
       <object> findMyParameters
       <unknown> createParser <object>params
       <void> start
       <void> startWithParameters <object>params
       <void> stop
   
    
4. To stop and restart the AM-PM event driver, run the following commands in sequence:

          ./dmctl -s <SAM_Domain> invoke GA_DaemonDriver::INCHARGE-AM-PM_Event-Driver stop
          ./dmctl -s <SAM_Domain> invoke GA_DaemonDriver::INCHARGE-AM-PM_Event-Driver start

Similarly, in same way any underlying domain driver can be restarted.
