Cambio de IP de las System Controller E4900

Hoy vamos a ver como cambiar las IP de las dos System Controller de un Sun Fire E4900. Deberemos modificar la IP de forma remota, reiniciar y posteriormente cambiar la VLAN. El motivo es el de aislar la red de consolas de la red de servicio. Esperamos que con esto se solucione un problema que tienen las system controller, al parecer y según Oracle de forma extraoficial; "Se han encontrado que las consolas en redes con mucho tráfico acaban dejando de responder por ssh". Al parecer es nuestro caso. Actualmente la System Controller Slave no repsonde y de forma periódica debemos de reiniciarlas. 

Pasos a seguir

1. Reboot de la Slave System Controller
2. Conectar a la Slave System Controller
3. Cambiar la IP y red de la Slave System Controller
4. Cambiar la VLAN de la Slave System Controller
5. Hacer un cambio de Slave to Main.
6. Conectar a la Main System Controller
7. Cambiar la IP y red de la Main System Controller
8. Cambiar la VLAN de la Main System Controller
9. Hacer un cambio de Slave to Main.

Rebooting the SC is required for changes in the above network
settings to take effect.
Idle connection timeout (in minutes; 0 means no timeout) [0]: 10

server_sc0:sc>reboot

Esperar 5 minutos.

Cambiar la VLAN.

Hacer ping a la nueva IP y conectarse.

server_sc0:sc>showfailover -v
server_sc0:sc>setfailover on
server_sc0:sc>showfailover -v

Hacer un failover de forma manual.

server_sc0:sc>setfailover force
server_sc0:sc>showfailover -v

Comprobar que sc0 es la SC Main.
