Reboot a Server

A server should not be rebooted until you have assessed the full impact on the system. This list describes what happens when servers of different roles are rebooted:

• OAM Server controlling GUI session: Reboot of OAM Servers ends all GUI sessions controlled by that server. Note that the reboot may reboot the server controlling your GUI session. After the reboot sequence completes, you can re-establish a GUI session with the rebooted server. You are presented with a login screen and need to re-authenticate to create a new session.
• Active OAM Server: Stopping and starting application software may cause a switchover. You have different capabilities on Active versus Standby OAM servers, depending on the feature. For example, provisioning is only allowed from the active NOAMP server.
• Other Servers: Rebooting Message Processing servers and Standby OAM servers without GUI sessions has no direct GUI impact. You can observe changes in the status of these servers.

Caution:

Do not click Reboot for a server until you have assessed the impact on the system. Reboot temporarily halts all services on the designated server; do not perform a Reboot unless other servers within the network element can take over the traffic load.

Use this procedure to reboot a server:

1. Click Status & Manage > Server.
2. Click to select the server you want to reboot.
   Alternately, you can select multiple servers to reboot. To select multiple rows, press and hold Ctrl as you click to select specific rows.
3. Click Reboot.
   A warning message appears:

   Are you sure you wish to reboot the following server(s)? <server name>

4. Click OK to continue.

The specified server is rebooted. Rebooting the server influences the High Availability subsystem. The rebooted server's mate no longer detects HA heartbeats and raises an alarm.
