[MasthanUsha]

Hi All,
 
Any one og you have any idea on scsi inquiry command ?
 
I want to send an Inquiry command to a scsi device through sd path (.i.e.
/dev/sda or /dev/sdb) by using SG_IO ioctl. Please explain me...
 
 
Your help is appreciated

Masthan

If you look at http://www.torque.net/sg/sg3_utils.html
and fetch a tarball (e.g. sg3_utils-1.23.tgz) then have
a look at the examples/sg_simple1.c file.

In the lk 2.6 series, it will also work for "sd" devices
(and "hd" devices if they happen to be cd/dvd drives).

You have one already. Actually you have lots of examples there.

yes, in the lk 2.6 series.

 I am not sure.. I think it will work only for sg driver. Am I correct ?.

That was correct several years ago, not now.

download sg_utils3 and use the sg_inq command to do so
