Déterminer les chemins disques sur SAN et Veritas sur Solaris 10
Le sar utilise des références type ssdxx. Or avec Véritas les références disques apparaissent comme cxtyyyyyyydzsn avec la commande "vxdisk list", comment déterminer la correspondance avec les sddxx notifiés par le sar.
Premiere methode
La première commande permettant de faire une première correspondance est la conjonction entre iostat -nx et iostat -x.
iostat -nx :

0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.3 0 0 c1t5006048452A64456d14
0.0 0.6 0.3 3.4 11.8 0.0 20589.8 2.0 98 0 c0t5006048452A64459d9
iostat -x :

Seconde méthode
Il faut rechercher le device dans /etc/path_to_inst :
grep -w ssd path_to_inst | grep -w <no du ssd>
Le résultat rend une ligne du type : "/pci@1c,600000/lpfc@1/fp@0,0/ssd@w5006048452a64459,9" 58 "ssd"
Ensuite, il suffit de rechercher le lien correspondant dans /dev/dsk pour faire la correspondance avec les target lun cxtyyyyyyydzsn
