Logical address format

Use the logical address to identify the resource entry.

To sort by logical address, select the Analyze log option on the product activity log display. Then select the F9 key (Sort by...) and sort by logical address. For more information on the address, use the address information function.

The logical address format, A/B/C/D-E/F/G/H/J/K, has the following definitions:

A
Type of I/O bus (transport)
B
System bus number
C
System board number (for busses that connect card enclosures)
D
System card (bus unit) number
-
Separates the bus address from the unit address
E
Unit address type
FGHJK
Unit address data

The values of F, G, H, J, and K vary, depending on the unit address type (E). Use the following information to determine the unit address data (FGHJK) representation.

Table 1. Unit address (E) definitions

3 Workstation I/O bus Adapter Port Device Session
4 Auxiliary processor I/O bus Auxiliary processor Adapter Port -
5 Library I/O adapter I/O bus Library Controller Device
6 Cryptography I/O bus Adapter Device - -

The Logical address field contains the bus address and the unit address. The bus address describes the hardware bus, board, and card information. The unit address describes the subsystem and identifying data (see Table 1).

Note: To locate a device or card that is within the system unit, use the physical address information.
