These machines support both CIO and NIO. This section deals with NIO configuration.

The first two configuration levels consist of the device adapter address and the device address. A third level is required for SCSI devices or multi-unit HP-FL devices.

Device Adapter

To configure a device adapter with a path of 48, for example, enter:

   APATH 48,ID=nnnnn

Where nnnnn is a valid device adapter identifier such as HP28616A or HP28642A-SCSI.

HP-FL Devices

To configure an HP-FL device use the ADEV command and the device address. For example, for a device address of 2, you would enter:

   ADEV 48.2,ID=nnnnn

where nnnnn is a device identifier such as HP7937FL or HPC2474R.

If you are configuring an HP-FL device that is not a multi-unit device, you are done.

SCSI Devices

For a SCSI interface you must use the word PSEUDO as the device identifier as follows:

   APATH 48.2,ID=PSEUDO

Unit Identifier

The third level provides the unit address for multi-unit devices. It is required for SCSI devices regardless of whether they are single or multi-unit.

To configure a unit address of 3, for example, on the device configured above, enter:

   ADEV 48.2.3,ID=nnnnn

where nnnnn is a valid device identifier.

If the device is not a multi-unit device or if a multi-unit device is being configured as a single unit, the device unit address of 0 is used to complete the address. For example, to use the device configured above as a single-unit device, enter the following:

   ADEV 48.2.0,ID=nnnnn

where nnnnn is a valid device identifier.
