Devices that are connected to the system can be in one of four states.

Devices that are connected to the system can be in one of the following states:

Item

Description

Undefined

The device is unknown to the system.

Defined

Specific information about the device is recorded in the customized database, but it is unavailable to the system.

Available

A defined device is coupled to the operating system, or the defined device is configured.

Stopped

The device is unavailable but remains known by its device driver.

If a tty device and a printer alternately use the same tty connector, both a tty device and a printer are defined on the same parent and port in the device configuration database. Only one of these devices can be configured at a time. When the tty connector is configured, the printer specific setup information is retained until it isconfigured again. The device is not removed; it is in the defined state. Maintaining a device in defined state retains customized information for a device that is not currently in use, either before it is first made available or while it is temporarily removed from the system.

If a device driver exists for a device, the device can be made available through the device driver.

To unconfigure a device and remove its definition from the Customized Devices object class in AIX, the commandrmdev -dl rmtOis used. The-doption indicates the removal of the device definition, and the-loption specifies the logical name of the device. This command ensures that both the device configuration and its definition are deleted from the system.References:= IBM AIX Documentation

The root user is not required to run SMIT, and the size of the window is the only factor that determines the minimum output display requirements. According to the IBM AIX v7 Administrator Specialty Study Guide (page 9-3), SMIT requires 24 lines and 80 columns for the output display for successful execution.

The error message1800-005 SMIT requires a minimum of 24 line by 80 column output displayindicates that the terminal window does not meet the minimum size requirements for runningsmit. To resolve this, the user needs to resize their terminal window to at least 24 lines by 80 columns. Ensuring the terminal meets this size requirement will allowsmitto display its interface properly.References: IBM AIX Documentation – SMIT
