Re: proc_name in sysfs

[Frederic TEMPORELLI <frederic.temporelli@bull.net>]

Hi,


Sorry, no such "driver" directory in /sys/class/scsi_host/hostX/
(checked: Emulex "lpfc" 8.0.24 and LSI "mptscsih" 3.01.18)

note: there's also a "proc_name" interface for LSI "mtpscsih", located in 
/sys/class/scsi_host/hostX/, which is reporting "mptscsih" string.

Any other ideas ?

Best regards.
