Conecta un disco regional a una instancia de VM de Compute Engine en modo de lectura y escritura.
Conecta un disco regional a una sola máquina virtual que se ejecuta en Google Compute Engine. El sistema operativo también debe activar el disco antes de que se pueda usar.
El disco se conecta en modo de solo lectura. El disco se puede conectar a varias instancias de VM de forma simultánea.
