Demand test descriptions and error codes - Avaya Support

CAUTION: Entering
Note: ATM
ESS (Enterprise Survivable Server)
6. Use either Avaya Fault and Performance Management or the SAT commands
status ess port-network and status ess clusters to verify that all servers
and network resources are operational.
! CAUTION:
the commands below will cause a service interruption. When Port
Networks switch to either a Main server or ESS server, a level 2 restart is initiated
on the Port Network, and service will be interrupted to the entire Port Network.
Note that shuffled IP to IP calls will not be dropped, but during the restart, they will
not have any access to features (Hold, Transfer, Conference, etc.).
7. When the Main server(s) and network are operational and stable, schedule or initiate
an on-demand switchback of Port Networks to the Main server. On the Main server,
use these commands:
Note:
PNC
When a Port Network which is providing control for other sub-tending Port
Networks via an ATM Expansion Interface (ATM-EI) circuit pack switches to a
server, the other sub-tending Port Networks may or may not end up being
controlled by the same server. All IPSI controlled Port Network(s) in the
configuration will vie for control of the sub-tending Port Networks. The only way to
guarantee that ATM-EI controlled Port Networks will be controlled by the same
server is if all IPSI controlled Port Networks are controlled by that same server.
● Schedule a switchback to the Main with the change system-parmeters ess
command. See Using Avaya Enterprise Survivable Server (ESS) for more
information. The Auto Return field may be set to scheduled or no. If no is used,
the only way to initiate a switchback is by using an on-demand command (See
below). The survivable-processor and system-parameters
port-networks administration screens may be displayed on all ESS servers but
may only be changed on the Main server.
● Initiate an on-demand switchback by entering the get forced-takeover
ipserver-interface port-network N command. This command may be
issued with a qualifier for all Port Networks or a single individual port-network
N.
b. Error Type 257: This error applies to a Main or ESS server. This error is generated when an
ESS server is translated on the Main but is NOT registered with the Main.
