The drive is a standard connector, 2.1 Gbyte SCSI low profile disk drive. It is
approximately 1 inch high and 3.5 inches wide. It supports fast SCSI at
10 Mbytes per second.
When you examine your 2.1 Gbyte disk drive, locate the label that has the Sun
part number to determine which vendor manufactured it. Disks with the
370-2067 part number are manufactured by Seagate, disks with the 370-1957
part number are from IBM. While all performance specifications are the same
for both drives, the jumper locations and settings are different. Once you have
identified which drive you have, follow the instructions for that specific drive
only.
Mounting Hardware
When you unpack the disk drive, remove the plastic bags that contain various
mounting brackets, screws, grommets and cables. The bags are labeled:
•Multi-Disk Pack
•Desktop Disk Pack
Open only the appropriate bag for your system. Put the other bags aside.

Before You Start 1-3

Tools and Equipment •Phillips screwdriver, #2
•Container for screws
•Needlenose pliers (for disk drive jumper settings)
•Antistatic mat or the antistatic bag in which the disk drive was shipped
•Disposable antistatic wrist strap
•SCSI regulated terminator
Verifying the Software Environment Version
Before you begin any procedures, verify which software environment you have
running on your system:
♦Type uname -rs and press Return.
Shutting Down the System
Before you can install the disk drive, you must shut down the system. If you
omit a step, the system may fail to boot, or fail to correctly configure the disk
drive.
•To shut down the Solaris 2.x software environment, proceed to the next
section.
•To shut down the Solaris 1.1.x software environment, see the section“Solaris
1.1.x Software Environment” on page 1-6.
If the message displayed is: Your software environment is:
SunOS 5.x Solaris 2.x
SunOS 4.1.3_U1 Version B Solaris 1.1.1 SunSoft Version B

Solaris 2.x Software Environment
1. Become superuser by typing su and your superuser password.
If you do not know your superuser password, contact your system
administrator.
The root prompt (#) is displayed.
Caution – The system will not recognize the new device unless you follow the
shutdown procedures for your operating system. Only Solaris 2.x software
uses the touch /reconfigure command to ensure autoconfiguration when
the system is powered on.
2. Type touch /reconfigure.
This command ensures that the operating system checks for the presence of
any newly installed peripheral devices when you power on or boot your
system later.
If you omit this step, you can still automatically configure the new drive
when the system boots by using the -r option:
Note – If your system is acting as a server, inform the mounted users that you
are shutting the system down as described in Step 3. If your system is a stand-
alone system, use the halt,shutdown,orinit 0 command instead.

Locating the Jumpers and Verifying their Settings
Each SCSI device in your system needs a specific and unique SCSI address.
This section identifies the 2.1 Gbyte disk drive jumpers and provides jumper
settings for all supported systems except the Multi-Disk Pack.
For Multi-Disk Pack disk drive jumper locations and settings, see “Setting
Jumpers and Preparing the Disk Drive for Installation” in Chapter 3, “Multi-
Disk Pack.”
Note – Make sure you are wearing a wrist strap when you handle the drive to
check the jumper settings. Make sure that the external power cord is connected
to the subsystem and power outlet. Do not have the subsystem powered on
when you do this.
1. Make sure the drive is on an antistatic surface with the PCB side visible.
2. Locate the jumper blocks on the drive and verify that the pins are
correctly jumpered.
•See Figure 1-1 on page 1-9 for the IBM drive.
•See Figure 1-2 on page 1-11 for the Seagate drive.
