SCSI Linux
« on: July 25, 2020, 05:56:24 pm »
 have installed sg3 utils software.

I want to send a command to the SCSI device (/dev/sr0).

command = ef 01 ff ff ff ff 01 00 03 01 00 05

How can send above command to the SCSI device using
sg_raw?

Thank you for your help.

As man sg_raw says,
    sg_raw /dev/sr0 ef 01 ff ff ff ff 01 00 03 01 00 05

That means that the sequence either needs changing (because it requires data, or produces a response), or is incorrect for some other reason.

Why don't you tell us what it is you are trying to achieve by sending that command sequence?
