Synchronizing the MPP or auxiliary EPM clock with the primary EPM

Procedure

If you are working with an MPP server and the MPP software is running, stop it using the EPM web interface:
1. Log on to the EPM web interface by using an account with the Administration or Operations user role.
2. From the EPM main menu, select System Management > MPP Manager.
3. On the MPP Manager page, click the selection box associated with the MPP that you want to stop, then click Stop in the State Commands group.
4. Confirm the action when requested.
5. Wait until the operational state changes to Stopped.
  
  To check this, click Refresh and look at the State field.
  
  Note:
  
  The operational state changes when the last active call completes or the operational grace period expires, whichever comes first.
If necessary, log in to Linux on the server.
- If you are an Avaya Services representative, and use Avaya Enterprise Linux, or if the Avaya Service accounts are installed on this server, log on to the local Linux console as root.
- Otherwise, log on remotely as a non-root user, and then change the user to root by entering the su - root command.
If you are working with:
- An MPP server, stop the mpp process by entering the /sbin/service mpp stop command.
- The auxiliary EPM server, stop the vpms service by entering the /sbin/service vpms stop command.
Restart the chronyd process by entering the systemctl restart chronyd command.

To verify that chronyd is operating properly, enter the chronyc tracking command.

The system displays a status message similar to the following:

Reference ID    : 0A868E42 (10.134.142.66)
Stratum         : 4
Ref time (UTC)  : Thu Sep 17 12:47:44 2020
System time     : 0.000000488 seconds fast of NTP time
Last offset     : +0.000008485 seconds
RMS offset      : 0.000039525 seconds
Frequency       : 24.108 ppm slow
Residual freq   : +0.001 ppm
Skew            : 0.030 ppm
Root delay      : 0.147401720 seconds
Root dispersion : 0.003942181 seconds
Update interval : 1037.7 seconds
Leap status     : Normal

Verify that the Reference ID points to the Primary EPM server.

If you are working with:
- An MPP server, start the mpp process by entering the /sbin/service mpp start command.
- The auxiliary EPM server, start the vpms service by entering the /sbin/service vpms start command.
Verify the service has started by entering the /sbin/service mpp status or /sbin/service vpms status command.

	Note:
	The operational state changes when the last active call completes or the operational grace period expires, whichever comes first.
