Installing an IDE Device
This section outlines the procedure used to install an IDE device on your
system. The procedure has been divided into several tasks that must be performed
in order.
Prerequisites
Task 1 - Determine the Number and Location of the IDE Controllers
Determine how many IDE controllers are attached to your system unit and
where the IDE controllers are located. An IDE adapter may be in an adapter
slot or built into the system planar. Remember that IDE adapters have two
IDE controllers (IDE buses). Thus, two IDE controllers are found in an adapter
slot or built into the system planar.
You can obtain this information two different ways:
- Using a software configuration command. This method is available only
when the operating system has been installed on the system unit.
- Using the About Your Machine document shipped
with your system unit. This method is valid only for initial setup and installation
of a new system unit.
Using a Software Configuration Command
This method applies to a system that already has the operating system installed.
To list the IDE I/O controllers on the system, type the following commands:
lscfg -l ide*
Examine the list of IDE controllers that are displayed. The following sample
display from the lscfg -l ide command shows two IDE I/O controllers. Controller ide0 and ide1 are located
on the system planar. The planar indicator is the second digit in the location
value with a value of 1.
DEVICE LOCATION DESCRIPTION
ide0 01-00-00 ATA/IDE Controller Device
ide1 01-00-01 ATA/IDE Controller Device

slot number
Initial Setup
Use the About Your Machine document to determine
the IDE I/O controllers on the system if the device is being installed during
initial setup.
Note
Incorrect results are produced if controllers have been added
after the system was shipped from the factory.
Determine whether the system unit has an IDE controller built into the
planar board. A built-in IDE I/O controller is standard on some system units.
Your system unit has a built-in IDE controller if About
Your Machine document shows an internal media IDE device with a blank
slot number.
Task 2 - Select an IDE Controller and an IDE Address on the Controller
After identifying the IDE controllers attached to the system unit, select
the IDE I/O controller to which you want to connect a device. This IDE I/O
controller must have at least one IDE setting that is not already assigned
to another device.
Determine whether IDE device setting must be jumpered as master or slave.
If no device is currently attached to the controller, the IDE device jumper
must be set to master (some devices require no device ID setting in this situation).
If an IDE device is already attached, the type of device must be determined.
Disks are ATA devices. CD-ROM and tape are ATAPI devices. If ATA and ATAPI
devices are both attached to the same IDE controller, the ATA device must
be set to master ID and the ATAPI device must be set to slave ID.
Determine what IDE devices are attached to a controller by viewing information
about the devices already connected to the IDE controllers.
You can use two methods to select an IDE I/O controller and an IDE address
on the controller that is not already assigned to another device:
- Using a software configuration command if the operating system is already
installed on the system unit.
- Using the About Your Machine document for initial
setup and installation of a new system unit.
Using a Software Configuration Command
This method applies to a system that already has the operating system installed.
- Type the following command to list all the currently defined IDE devices:
lsdev -C -s ide -H
- Examine the list of devices already assigned to each IDE controller. Each
row in this display shows the logical name, status, location, and description
of an IDE device. The location for each device begins with the location of
the controller that the device is connected. In the sample below, the IDE
I/O controller with address 01-00-00 has two IDE devices attached. The IDE
I/O controller with location 01-00-01 has one IDE device attached.
name status location description
hdisk0 Available 01-00-00-00 720 MB IDE Disk Drive
hdisk1 Available 01-00-00-01 540 MB IDE Disk Drive
cd0 Available 01-00-01-00 IDE CD-ROM Drive

IDE controller address (6th digit)
- Select a controller that does not have two IDE devices already connected.
- If one device is already attached to the controller, determine the type
of the device. Also determine the type of device to be installed. Disk devices
are classified as ATA devices. CD-ROM and tape devices are classified as
ATAPI devices.
- Determine the IDE jumper setting for the new device depending upon the
combination of devices to be connected to the IDE controller. If the new device
is the only device connected to the controller, the device jumper setting
must be set to the master position (some devices require no setting in this
case). If both devices are the same type, the new device jumper setting can
be set to the slave position. If there is a mix of devices (ATA and ATAPI),
the ATA device jumper must be set to the master position and the ATAPI device
jumper must be set to the slave position. If there is a mix of devices and
the new device is an ATA device (disk), the device jumper for the currently
existing ATAPI device must be changed to the slave position and the new ATA
device jumper must be set to master. If there is a mix of devices and the
new device is an ATAPI device (CD-ROM or tape), the device jumper for the
new ATAPI device must be set to slave and if the ATA device does not currently
have a jumper setting, it must be set to master.
Initial Setup
Use the About Your Machine document to determine
the devices assigned to the IDE I/O controllers on the system if the device
is being installed during initial setup.
Note
Incorrect results are produced if controllers have been added
after the system was shipped from the factory.
- To determine the IDE devices assigned to addresses on the IDE controllers,
see "Internal Media Devices" in About Your Machine.
- Select a controller that does not have two IDE devices already connected.
- If one device is already attached to the controller, determine the type
of the device. Also determine the type of device to be installed. Disk devices
are classified as ATA devices. CD-ROM and tape devices are classified as
ATAPI devices.
- Determine the IDE jumper setting for the new device depending upon the
combination of devices to be connected to the IDE controller. If the new device
will be the only device connected to the controller, the device jumper setting
must be set to the master position (some devices require no setting in this
case). If both devices are the same type, the new device jumper setting can
be set to the slave position. If there is a mix of devices (ATA and ATAPI),
the ATA device jumper must be set to the master position and the ATAPI device
jumper must be set to the slave position. If there is a mix of devices and
the new device is an ATA device (disk), the device jumper for the currently
existing ATAPI device must be changed to the slave position and the new ATA
device jumper must be set to master. If there is a mix of devices and the
new device is an ATAPI device (CD-ROM or tape), the device jumper for the
new ATAPI device must be set to slave and if the ATA device does not currently
have a jumper setting, it must be set to master.
Task 3 - Setting Up the Hardware
Prerequisites
- Do not begin this task until you have selected and recorded the following:
- Position of the IDE I/O controller where the device will be connected
(either built-in or identified by an adapter slot number).
- IDE address for the device.
- Determine the physical position on the system unit to connect the selected
IDE controller. For example, locate the position of the built-in IDE controller.
Refer to the operator's guide for help.
Procedure
- Shut down the system unit using the shutdown command after stopping all applications that are currently
running. Type shutdown -F to stop the system immediately
without notifying other users.
- Wait for the message Halt Completed or a similar
message to be displayed.
- Turn off the system unit and all attached devices.
- Unplug the system unit and all attached devices.
- Make the physical connections following the procedure described in the
setup and operator guide.
Note
Do not power on the system unit;
proceed to the next task.
Task 4 - Add the Device to the Customized Configuration Database
This task makes the device known to the system. During system unit startup,
the operating system reads the current configuration and detects new devices.
A record of each new device is added to the customized configuration database
and are given default attributes.
If the device is being installed on a new system unit, the operating system
must be installed. Instructions for installing the operating system are included
in the installation guide for the operating system.
Follow this procedure to add a device to the customized configuration database:
- Plug in the system unit and all attached devices.
- Turn on all the devices, but leave the system unit turned off.
- Turn on the system unit when all the attached devices have completed power-on
self-tests (POSTs).
Note
The startup process automatically detects
and records the device in the customized configuration database.
- Confirm that the device was added to the customized configuration database
using the Web-based System Manager (type wsm ), or the SMIT fast
path, smit lsdidea. A list of all defined devices is
displayed. Look at the location field for the IDE adapter and IDE address
values of the device you just installed.
Task 5 - Customize the Attributes for the Device (Optional)
Default attributes are assigned to a supported device when it is added
to the customized configuration database. These attributes are appropriate
for typical use of the device. Change the device attributes when the device
you are installing is not supported or when you need to customize some part
of the device's operation. For example, you might need to change your tape
drive to write tapes in a lower-density format.
To customize the attributes for a device use the SMIT fast
path, smit dev.
