Setting Up a Disk Drive

2

Be sure to read the requirements before you start to configure the operating system for a new disk drive.

Requirements

Before you start to configure the operating environment for a new disk drive, you must have:
  • Installed the Solaris 2.4 operating environment
  • Shut down the system and those peripherals that are already connected as described in Chapter 1, "Before You Start"
Note - If you did not follow the procedures as described in Chapter 1, "Before You Start," the operating system may not recognize the presence of the new disk drive.
  • Installed the disk drive as described in the hardware installation manual that accompanies your disk drive. If you have not yet installed your disk drive, do so now before you proceed.

    This task includes finding the location of the address switch or jumpers on the disk drive as well as setting the SCSI target ID.

Note - When installing a fast SCSI drive, be sure to connect external drives with cables equipped with ferrite cores (for example, part number 530-1893 for desktop systems). Also, in SCSI chains with fast SCSI drives, be sure to use a regulated terminator (for example, part number 150-1785).
Information on how device addresses (or logical names) are assigned is shown in Table 2-1.

Configuring the System

When you boot the system after adding a disk drive, the Solaris 2.x operating environment automatically configures the system by assigning a device address to a disk drive if the:
  • SCSI switch or jumper settings are correctly set.
  • Operating environment has been properly shut down as described in Chapter 1, "Before You Start."
To configure the system for the addition of a disk drive:
  1. Note the address that is assigned to the disk drive.

    Refer to Table 2-1 to see how the SCSI address switch or jumper settings determine the device address that is assigned. You should already have correctly set the physical SCSI switch or jumpers on your disk drive, as described in your disk drive installation manual and Chapter 6, "Selecting Addresses."

    For example, the first internal disk drive usually has jumper settings that have been preset by the factory to SCSI target ID 3. If your system has a second internal disk drive, the factory usually sets the jumpers to SCSI target ID 1. External disk drives are usually preset to SCSI target ID 3 by the factory.

    Because the internal disk drive has been preset to SCSI target ID 3, you must change the default SCSI setting of your external disk drive to an unused target ID.

    Each SCSI target ID determines the device address the Solaris 2.x operating system assigns to the drive.

Note - If you have more than one SCSI device, such as a disk drive, you must set each SCSI address switch to a different address.
  1. Turn on power to all external peripheral devices, including the disk drive that you plan to configure, and then the system.

    The system automatically boots and configures the new drive.

CAUTION Caution - Since each disk drive must have a unique SCSI target ID setting, the SCSI address switches on your disk drives may need to be set to different numbers than those shown in Table 2-1. For further information on device addresses, go to Chapter 6, "Selecting Addresses" in this handbook.

  1. Type your superuser password and press Return.

    If you type the password correctly, you have superuser access to your system. The root prompt (#) is then displayed.

  1. Format the disk if necessary.

    For information on how to format this disk, go to Chapter 7, "Preparing Media" in this handbook.

Note - This task is optional; many disks have already been formatted at the factory.
  1. Partition the disk if necessary.

    For information on how to partition a disk, go to Chapter 7, "Preparing Media" in this handbook.

Note - This task is optional; many disks have already been partitioned at the factory.
  1. Label the disk.

    For information on how to label a disk, go to Chapter 7, "Preparing Media" in this handbook.

  2. Prepare a file system for each partition.

    For information on how to prepare a file system, go to Chapter 7, "Preparing Media" in this handbook.

  3. Mount each file system.

    For information on how to mount each file system, go to Chapter 7, "Preparing Media" in this handbook.

Note - Be sure not to mount any partition that you intend to use as swap space or as an unmounted partition.
This completes the tasks required to set up your disk drive.
