Solaris 11 : configuration du pool racine ZFS en miroir
Boris HUISGEN
|
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.
