Mémo du SAN sous Linux

Il faut avoir le binaire : /usr/bin/systool

Vérification de la présence du package :

# rpm -qf /usr/bin/systool
sysfsutils-2.1.0-1.el5
 

# sinon :

yum install sysfsutils

Pour connaître les ports reconnu sur le serveur Linux :

# systool -c fc_host
Class = "fc_host"
 Class Device = "host3"

 Device = "host3"
 Class Device = "host4"

 Device = "host4"
