To configure a SCSI device, it must be physically connected to the specified path, it must be operational, and
there must be a device-defaults-data entry for the product ID (which is obtained from the device during
configuration). If you omit the ID parameter, the IOCONFIG utility interrogates the hardware to identify the
device. It then validates the ID that it retrieves by checking it against the list of supported devices.
When adding a printer to the configuration that has the class SPOOL, the spooler process for that device will
automatically be started and a message indicating this will appear on the console.
Listing One or More Devices with IOCONFIG
The system manager or operator can list all devices in the system or one or more specified devices along with
their configuration information using the LISTDEVICE or LDEV command. When you enter either command
without parameters, information about all devices currently configured in the system is listed. By providing
one or more parameters as the selection criteria, you can see information about particular devices.
The command syntax is as follows:
LISTDEVICE {[LDEV]=#/#,#,...}
[[ID]=product number]
[[TYPE]=device type]
[[CLASS]=classname,...]
[[DEST]=OFFLINE]
