Hoy vamos a crear un entorno de pruebas para cabinas de almacenamiento Netapp. Se trata de un simulador de Data ONTAP (Sistema operativo de Netapp) con el cual podremos disponer de una cabina 100% funcional sobre la que hacer pruebas y modificaciones sin necesidad de utilizar las cabinas de producción.
El simulador se puede descargar desde el sitio web oficial (con registro). Esta es la dirección.
Vamos a proceder a la instalación, es realmente sencilla. Descomprimimos el fichero descargado y ejecutamos el setup (como root) del simulador:
# gunzip 7.3.4-tarfile-v22.tgz # tar -xvf 7.3.4-tarfile-v22.tar # sudo ./setup.sh
La salida de la instalación es similar a lo siguiente, veréis que os hace una serie de preguntas. Tenemos la posibilidad de añadir los discos que estimemos necesarios, crear un cluster, etc.
Script version 22 (18/Sep/2007)
Where to install to? [/sim]:

Adding 9 additional disk(s).
Complete. Run /sim/runsim.sh to start the simulator.
Procedemos a arrancar el simulador:
sudo /sim/runsim.sh
En el primer arranque, se ejecutará el asistente al igual que en una cabina real, donde configuraremos la red, hostname y demás configuraciones iniciales:
