2.5.2.3 Problems with SCSI controllers and devices

 

   

Presented here are some of the most common problems with SCSI controllers and devices such as CD-ROMs, hard drives, and tape drives. If you are having problems getting Linux to recognize your drive or controller, read on.

The Linux SCSI HOWTO (see Appendix A) contains much useful information on SCSI devices in addition to that listed here. SCSI can be particularly tricky to configure at times.

If your SCSI controller is not recognized, you may need to force hardware detection at boot time. This is particularly important for BIOS-less SCSI controllers. Most distributions allow you to specify the controller IRQ and shared memory address when booting the installation media. For example, if you are using a TMC-8xx controller, you may be able to enter

boot: linux tmx8xx=,

at the LILO boot prompt, where is the IRQ of controller, and is the shared memory address. Whether or not you will be able to do this depends on the distribution of Linux you are using; consult your documentation for details.
