Use this procedure to determine the IOP, IOA, or device address
from either a control panel or a console display.
Use this procedure
to determine the IOP, IOA, or device address from either a control panel or
a console display.
- Was the SRC and addressing information obtained either from a control
panel display, the Main Storage Dump Manager display, or the HMC Partition
Properties Reference Code words display?
- No: Continue with the next step.
- Yes: Addressing information is in the Bus-Bus-Bus-Bus/Card-card/board-board
(BBBBCcbb) format as follows:
- If characters 7 and 8 of the top 16-character line of function 12 (word
two) are 60:
- The direct select address is characters 1-8 of the bottom 16-character
line of function 12 (word four) in the format "BBBBCcbb".
- The device address is characters 9-16 of the bottom 16-character line
of function 12 (word five) in the format "abcd efgh".
- If characters 7 and 8 of the top 16-character line of function 12 (word
two) are 13, 17, 27, or 29:
- The direct select address is characters 9-16 of the top 16-character
line of function 12 (word three) in the format "BBBBCcbb".
- The device address is characters 1-8 of the bottom 16-character line
of function 12 (word four) in the format "abcd efgh".
- If characters 7 and 8 of the top 16-character line of function 12 (word
two) are 62:
- The direct select address may be characters 9-16 of the top 16-character
line of function 13 (word seven) in the format "BBBBCcbb".
- The device address may be characters 1-8 of the top 16-character line
of function 13 (word six) in the format "abcd efgh".
Go to step 9.
- Are you using the Service Focal Point on the HMC?
- No: Continue with the next step.
- Yes: Go to the i5/OS® partition
with the problem and use the Service Action Log (SAL) to find the entry related
to this problem (see Using
the Service Action Log), and then go to step 7.
- Are you using the Service Action Log (SAL)?
- No: Continue with the next step.
- Yes: Go to step 7.
- Are you using i5/OS communication-diagnostic
panels that are displayed by the commands VFYCMN, WRKPRB, or ANZPRB?
- Yes: Go to step 11.
- No: Continue with the next step.
- Addressing information is in the Bus/Board/Card format.
Note: This
format shows the system bus number in decimal form.
If no address
information is available in the console error message, check the Product
Activity Log (PAL)
entry that is associated with the console error message. Below is an example
of a PAL display
for a storage device. Other devices (for example, workstations or communications)
have similar displays. For more information about the PAL, see Product Activity Log in the Service functions.

In
the above example, the contents of "Storage" are defined as follows.
Table 1. Storage definitions| Reference |
Description |
|---|
| I/O Bus |
This is the SCSI bus to which the device is connected. |
| I/O Adapter |
This is the adapter that the I/O bus connects to on the I/O processor. |
| Controller |
This is the logical controller for the addressed device. |
| Device |
This is the logical device that is attached to the logical device
controller. |
- Use the figure below to understand how addresses
in the Bus/Board/Card format relate to the Bus-Bus-Bus-Bus/Card-Card/Board-Board
format. You can also use it to understand how addresses in the
Bus/Board/Card format relate to the direct select addresses used in Finding part locations.
Note: When converting from Bus/Board/Card format to Bus-Bus-Bus-Bus/Card-Card/Board-Board
format, the numbers must be converted from Decimal to Hexadecimal.
Go
to step 10 for IOA and device
address information.
- Display the FRU details for the problem that you
are attempting to fix. The location information in the field-replacable
unit detail is only available for IOPs, IOAs, and devices.
Is the FRU an
IOP, IOA, or device, and is there location information in the Location
field of the display?
- No: Continue with the next step.
- Yes: Use the location information and return to
the procedure that sent you here. This ends the procedure.
- There is no location information in the Location field. Are
there additional words displayed at the top of the screen?
- The BBBBCcbb format is the hexadecimal direct select
address of a card location in the system unit. The format definition
is:
- BBBB—System Bus
- Cc—System Card
- bb—System Board
Continue with the next step for IOA and device address information.
- Unit (Device) Address Definitions are explained
in an "abcd efgh" format. For example, if the unit address is
0001 00FF, the address relates to the "abcd efgh" format as follows:
Figure 3. Example of Unit (Device) Address definitions 0 0 0 1 0 0 F F
(a b c d e f g h)
The characters "abcd efgh" can have different meanings, depending
on the subsystem that reports the problem. However, they define the information
that is contained in the unit (device) address as follows.

Note: If the failing item or procedure that sent you here indicates
that the I/O adapter is the failing item, but you only have a device address,
convert the device address into an I/O adapter address by making the last
7 digits FFFFFFF so that the address becomes xFFFFFFF, where x is the I/O
adapter number.
Note: If the unit (device) address appears as FFFF FFFF,
the address cannot be determined.
This ends the procedure.
- i5/OS communication-diagnostic
panels that are displayed by the commands VFYCMN, WRKPRB, and ANZPRB use the
following address format:
x1 x2 x3x4
Table 3. Decimal address values| Value |
Description |
|---|
| x1 = System bus |
The one, two, or three digit decimal representation of the hexadecimal Bus
value of the Bus-Bus-Bus-Bus/Card-Card/Board-Board format Address at
the top of Figure 2. Format conversion. |
| x2 = System board |
The one or two digit decimal representation of the hexadecimal Board value
of the Bus-Bus-Bus-Bus/Card-Card/Board-Board format Address at
the top of Figure 2. Format conversion. |
| x3 = System card |
The one or two digit decimal representation of the hexadecimal Card value
of the Bus-Bus-Bus-Bus/Card-Card/Board-Board format Address at
the top of Figure 2. Format conversion. |
| x4 = Adapter location |
The one or two digit decimal representation of the hexadecimal b
Adapter value of the Communications unit address value
in step 9 (See step 10). |
- Return to the procedure that sent you here. This
ends the procedure.
