Domanda: Come faccio a cercare l'indirizzo wwn della mia scheda HBA installata sul sistema Linux. Ho bisogno di queste informazioni per creare la suddivisione in zone del mio switch Fibre Channel.
Risposta: Utilizzare uno dei metodi seguenti per visualizzare l'indirizzo WWN HBA su Linux.
Metodo 1:/sys/class/scsi_host/host{n}/device/fc_host:host{n}/file nome_porta
Su Redhat 5 e versioni successive (inclusi OEL e CentOS), il file /sys/class/scsi_host/host{n}/device/fc_host:host{n}/port_name contiene le informazioni HBA WWN come mostrato di seguito. Sostituisci n con 0, 1 o 2 in base al tuo sistema.
Ad esempio:
$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.3 (Tikanga) $ cat /sys/class/scsi_host/host1/device/fc_host:host1/port_name 0x2100001c111111c1
Metodo 2:/proc/scsi/{adapter-type}/{n} File
In Redhat 4 e versioni precedenti (inclusi OEL e CentOS), il file /proc/scsi/{adapter-type}/{n} contiene le informazioni HBA WWN come mostrato di seguito.
{adapter-type} può essere qlaxxxx per gli adattatori QLogic (o) lpfc per gli adattatori Emulex.
Per favore sostituisci n con 0, 1 o 2 in base al tuo sistema.
L'esempio seguente mostra il numero WWN dell'adattatore qlogic 2300 su RedHat 3.
$ cat /etc/redhat-release
Enterprise Linux Enterprise Linux AS release 3 (Update 9)
$ cat /proc/scsi/qla2300/1
