Adding SCSI, ATAPI, and USB removable storage drives

The Sflp device driver is the SCSI peripheral driver for SCSI, ATAPI, and USB removable storage devices that are not recognized by the fd(HW) driver as a standard floppy drive. Such devices include:

• SuperDisk 240 (LS-240) drives

• SuperDisk 120 (LS-120) drives

• floppy drives

• floptical drives

The device files used to access these types of removable storage devices are documented on the Sflp(HW) manual page.

When installing a SCSI removable storage device (for example, an LS-120, LS-240, or floptical drive), you must use a SCSI host adapter supported by SCO OpenServer systems. You should also check with your hardware supplier that the drive will work with the host adapter. A maximum of seven drives on a single SCSI bus per system are supported.

To add a removable storage drive:

1. As root, put the system into maintenance mode.

   NOTE: For USB devices, it is recommended that you shut the system down before attaching the drive and then reboot and put the system into maintenance mode. You can hot-plug a USB removable storage device, but the drive's USB device ID could change when the system is rebooted next, requiring you to modify the drive's configuration. See the usb(HW) manual page for more details.

2. Select the desired removable storage drive from the devices listed by the Hardware/Kernel Manager, or enter the command mkdev flopti or mkdev ls120.

3. Select to install the appropriate removable storage drive type from the menu.

4. If the floppy driver is not already linked into the kernel, configure it for use.

5. Enter the required configuration information for the drive.

   For SCSI drives, enter the SCSI host adapter type, the host adapter number, target ID, and logical unit number (LUN), as described in ``SCSI addresses''. If this is the first SCSI peripheral that you are adding to the SCSI bus controlled by a host adapter, you may need to supply additional hardware information about the adapter as described in ``Adding a SCSI peripheral device''.

   For USB drives, enter the drive's USB device ID and LUN. You can determine the device ID by running hwconfig -h and locating the drive's entry in the list of hardware. The id= field indicates the assigned USB device ID. (If you hot-plugged the drive, the USB device ID is provided in the kernel configuration message displayed on the console.)

6. If prompted to do so, relink the kernel, then reboot the system. You can defer relinking if you have other devices to configure.
