Disk Drives

Disk drives are common devices to add to a system. There are three major steps involved when adding a disk drive:

• Installing the disk (See ""To Add a Disk Drive"").

• Preparing the disk with the format utility (See "Preparing the Disk"").

• Creating and mounting the file systems (See "To Create a File System"").

The last step may not be necessary if you plan to use special (Redundant Array of Inexpensive Disks) applications such as Veritas Volume Manager or Solstice DiskSuite^TM software to manage the data on the disk.

To Add a Disk Drive

1. Shut down your system.

   See "Shut Down the System".

2. Check that the address switch for the disk drive has been correctly set.

   Each SCSI target ID determines the logical device name that the Solaris operating environment assigns to the drive. For more information about SCSI addressing refer to Appendix A, SCSI Addressing" in the appendix and to the System Administration Guide.

   Caution -

   Each disk drive must have a unique SCSI target ID setting.

3. Install the disk drive.

   For installation information, refer to the documentation that accompanies your hardware.

4. Turn the power on to the system and all the peripheral devices.

   In most cases, this will cause the system to boot. If the /reconfigure file is present (as described in "To Prepare the System"" in Chapter 1), then the operating system automatically assigns a logical device name and initializes the appropriate device drivers for the new device. If the /reconfigure file does not exist, you can achieve the same effect by performing a boot -r. See Appendix B, Booting Your System" for more information.

5. Prepare the disk, if necessary.

   See "Preparing the Disk".
