Adding hard disks

Configuring a SCSI hard disk

  1. Obtain the following information about the SCSI hard disk:

    See ``SCSI addresses'' and ``Adding a SCSI peripheral device'' for an explanation of what this information means and how to obtain it.

    If the disk is the first peripheral device that you are adding to the SCSI bus, you must also supply the following hardware configuration information about the host adapter:

  2. Log in as root and put the system into maintenance mode.

  3. Select Hard Disk from the devices listed by the Hardware/Kernel Manager, or enter the command mkdev hd. (Enter mkdev hd -u or mkdev hd -h if you require detailed usage and help information for mkdev.)

  4. If your root disk is attached to an ST506, IDE, EIDE, UDMA, ESDI, or USB-interface controller, specify that you want to add a hard disk to the SCSI bus.

    If your root disk is attached to a SCSI controller, specify that you want to add another SCSI disk.

  5. Enter the SCSI host adapter type, and the number of the host adapter.

  6. If you are adding the first device to a host adapter, confirm that you wish to change its setup parameters, enter the hardware details about the host adapter card and confirm that you want to save these values.

    You can exit at this point if you have entered the wrong details.

  7. To install a controller on a host adapter that controls two SCSI buses, specify to which bus (0 or 1) the controller is connected.

  8. Enter the SCSI bus number, target ID of the controller and the LUN of the disk on the controller.

    The information you have supplied is displayed:

       Adapter		Adapter
       Type    Device  Number  ID      LUN     Bus
       ad      Sdsk    0       1       0       0
    This example shows a SCSI hard disk with controller ID 1 being added to the first Adaptec AHA-154x host adapter on a system. The bus number is shown as 0 as this is a single bus host adapter.

    If the information is correct, confirm that it should be used to update the SCSI configuration. Otherwise, start the configuration again, or exit.

  9. You are given the option of relinking the kernel. If you have more devices to add, you can defer doing this until later.

  10. When you have relinked the kernel, use the System Shutdown Manager or the shutdown command to shut down the system, then reboot.
After rebooting the system, you must run mkdev hd or the Hardware/Kernel Manager a second time to partition the disk as described in ``Installing a hard disk''.
