These systems require a four or five-level address consisting of the bus converter number, the channel adapter module number (interface slot number), the device adapter number the device address, and possibly a unit address. HP-FL, HP-IB and some SCSI devices are supported.

Bus Converter

To configure a bus converter number of 6:

   APATH 6,ID=nnnnn

where nnnnn is a bus converter identifier such as HPA1105A.

Channel Adapter

To configure a channel adapter module number of 4:

   APATH 6/4,ID=nnnnn

where nnnnn is a channel adapter module identifier such as HP19744A.

Device Adapter

To configure a device adapter with an address of 3 to the channel adapter module identifier:

   ADEV PATH 6/4.3,ID=nnnnn

where nnnnn is a device adapter identifier such as HP28616A.

HP-FL/HP-IB Devices

To configure a device with an address of 1 to the device adapter:

   ADEV PATH 6/4.3.1,ID=nnnnn

where nnnnn is a device identifier such as HP7937FL or HP7937H.

NOTE: For reasons relating to backward compatibility, optical disk library (SCSI device) configuration for CIO does not utilize the following PSEUDO device identifier. Instead, optical disk libraries are configured with a valid device identifier similar to HP-FL and HP-IB devices. For more information refer to the installation documentation for the device.

SCSI Devices

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

   PATH 6/4.3.1,ID=PSEUDO

Unit Identifier

The fifth-level provides the unit address for multi-unit devices (such as the Magneto Optical Device or a Cascade Disk Drive). It is required for SCSI devices regardless of whether they are single or multi-unit. It is required for HP-FL devices only when they are configured as multi-unit devices.

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

   ADEV 6/4.3.1.3,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 6/4.3.1.0,ID=nnnnn

where nnnnn is a valid device identifier.
