Redhat AS 4.O, emulex fiber channel hba and Hitachi

[Stephane Branchoux]

Hello,

I installed last emulex driver on a Redhat AS4.0 box (kernel 2.6.9-5.ELsmp )

Driver is loaded but i cant access Lun. All seems OK (Hitachi model, Lun 
number ...)
cat /sys/class/scsi_host/host6/port_name returns : 0x10000000c94a23d1 
(the good WWN)

When i run lun_scan 6, i have :

Any idea ?

Many thanks in advance.
