I have a machine running FC1 (kernel version 2.4.22-1.2188.nptl), and I want to use a Promise SuperTrak SX-6000. I downloaded the driver from Promise, compiled it, and loaded the resulting module. The module shows up as installed, the card is recognized according to dmesg, and it shows up in /proc/scsi/pti_st, denoted by scsi0. When I run scsi_info, I get the following: [root@nurban-temp pti_st]# scsi_info 0 could not get SCSI device info: Inappropriate ioctl for device My goal here is to find out what drives are connected to the device, or at least how to address the hardware-RAIDed drives such that I can format them. There was no documentation with the driver to help me accomplish this, and web searches have been fruitless. I am unsure if this is a problem with the interaction with the kernel and the driver, or I am issuing the wrong commands and/or parameters, or if it is something else entirely. Any help would be most appreciated. Regards, Rob
