Solaris 11 : configuration du pool racine ZFS en miroir
Cette procédure détaille la configuration en miroir du pool racine ZFS d’une installation de Solaris 11 x86 et reproductible pour un Solaris 10. L’installation du système a été réalisée sur le premier disque dur c4t0d0. Voici un mémo des commandes nécessaires.
