ESS (Enterprise Survivable Server)
Issue 1 June 2005 1149
At the Main:
1. Use display system-parameters ess to verify that the ESS server is properly
administered. A ESS server must be administered on the Main before it can register with
the Main. Record these values for use when troubleshooting the ESS server.
2. Use the SAT ping ip-address board <location> nnn.nnn.nnn.nnn command
to verify connectivity between the Main server and the ESS. Where board is the location
of the CLAN board the ESS server is trying to register with and nnn.nnn.nnn.nnn is
the IP address of the ESS server.
3. Use the display events command with a category of denial to display denial events
related to ESS. The ESS registration denial events are in the 36xx range. See ESS
Denial Events on page 254 for descriptions of individual ESS denial events.
4. Use the list trace ras ip-address command to monitor registration requests
from the ESS. This command will display registration requests from the ESS server and
the associated response from the Main server. Note that under normal operation a
Keep-Alive (KA) message is periodically sent from the ESS server to the Main server.
This should not be confused with a registration failure.
5. Firewalls or other security measures may preclude the Main server and ESS server from
communicating. Verify that these ports are open through the network between the Main
and the ESS:
● 1719 Registration between the ESS server and the Main.
● 21874 Filesync (rsync) between the Main server and ESS.
At the ESS server that is not registered:
!
CAUTION:
CAUTION: In the next steps be careful to use the Close Window button to cancel out of the
Configure Server page to avoid a reboot of the ESS. Do not Update the
system.
6. Use the bash ping nnn.nnn.nnn.nnn command to verify connectivity between the
ESS server and Main servers. Where nnn.nnn.nnn.nnn is IP address of the CLAN in
the Main that the ESS server is trying to register with. To determine which IP address the
ESS server is attempting to register with use the Configure Server command from
the Maintenance Web Interface on the ESS server to display the configure ESS
screen.
7. Firewalls or other security measures may preclude the Main server and ESS server from
communicating. Verify that these ports are open through the network between the Main
and the ESS:
● 1719 Registration between the ESS server and the Main.
● 21874 Filesync (rsync) between the Main server and ESS.
