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.

2/ now, how can we get the adapter module name from sysfs ?
Why do you need it?
Anyway, try lsscsi, it walks the sysfs tree:
[elm3b79 patman]$ lsscsi -H [0] qla1280 [1] qla1280 [2] qla2xxx [3] qla2xxx
Or, script it:
[elm3b79 tmp]$ more xx.sh #! /bin/sh
hdir=/sys/class/scsi_host
for i in ${hdir}/host* do host_dir=$(cd ${i}/device;/bin/pwd) driver_dir=$(cd ${host_dir}/../driver;/bin/pwd) module=$(basename ${driver_dir}) # echo ${i} is in: ${host_dir} echo "${i} module (driver) is: ${module}" done
[elm3b79 tmp]$ sh ./xx.sh /sys/class/scsi_host/host0 module (driver) is: qla1280 /sys/class/scsi_host/host1 module (driver) is: qla1280 /sys/class/scsi_host/host2 module (driver) is: qla2300 /sys/class/scsi_host/host3 module (driver) is: qla2300
Patrick, lsscsi currently uses proc_name so it needs to be changed to use the above logic (if LLDs are going to stop populating proc_name).
It has been suggested that I extend lsscsi to show transport info (as seen from the HBA) found in the various *_transport directories in sysfs.
Also I have been thinking about ways to list less tha all scsi devices. For example: "lsscsi 1:0:3:0" to look at one device and "lsscsi 1:-" for all scsi devices hanging off host1. I'm not sure whether "lsscsi /dev/sda" is a good idea. Any suggestions?
