System Management Guide: Operating System and Devices
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.
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.
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.

ide0 01-00-00 ATA/IDE Controller Device
ide1 01-00-01 ATA/IDE Controller Device

the adapter
slot number
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.
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.
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.
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.
- 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.
- 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.
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.
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.
