Exemple: T2000 fourni avec 2 disques 73Go, on va les mettre en miroir (RAID1)

Le RAID HW se configure avant que l’OS ne soit installé sur le disque. On boote en single-user, soit depuis le CDROM, soit sur le net, si un serveur Jumpstart est disponible.

A partir de là, et comme l’explique le document 85320, il faut re-”labeler” le disque avec la commande format, sinon ce message apparaitra:

WARNING: /pci@780/pci@0/pci@9/scsi@0/sd@0,0 (sd1):

        Label says 143359488 blocks; Drive says 143112591 blocks

Si vous utilisez Jumpstart, et avez oublié de re-labele le disque, le client Jumpstart va s’arrêter et vous aurez la main pour lancer la commande format. Ensuite, plutôt que de redémarrer la machine et recommencer le jumpstart depuis le début, taper simplement:

# install-solaris

Une fois que l’OS a été installé, on peut vérifier que le RAID est toujours actif:

t2000-root% raidctl -l
