Concurrently maintaining an Integrated xSeries Server

Before attempting to perform this procedure, download and install V5R2 PTFs MF32111 and

MF28881 on the iSeries primary partition.

To concurrently maintain an Integrated xSeries Server, enter the following commands on an

OS/400 command line:

1. Type go hardware. Press Enter.

2. Type 1 Work with communication resources. Press Enter.

3. Find the Integrated xSeries Adapter resource that you want to maintain. It has a Resource

name of LINxx, where xx is a decimal number, and a Type of 2689.

If you have multiple Integrated xSeries Servers, you need to determine the resource name

that corresponds to the physical xSeries server you want to maintain. If you know the

resource name, skip to the next step. To determine the resource name:

a. Remove the cover from the xSeries server you want to maintain.

b. Find the LED located on the Integrated xSeries Adapter adapter and record the hex

number displayed, for example, 06.

c. On the Work with Communication Resources display, type 7 against the resource

name LINxx, for example, LIN02. The resource must be of Type 2689.

d. Compare the Frame ID with the hex number displayed on the Integrated xSeries

Adapter LED. They must match. If not, you must find the correct LINxx resource that

matches the LED.

4. Once you have determined the correct resource name, check that there is no server

instance running on the xSeries server you want to maintain. You can check which

network server descriptions use this resource by typing 5 next to the LINxx resource. Use

the WRKCFGSTS *NWS command to check that the servers are varied off.

5. On the Work with Communication Resources display, type 7 against the LINxx resource

name. Record the Frame ID of the Integrated xSeries Adapter resource if you have not

done so already.

6. Exit to a command line and type STRSST. Press Enter.

7. Enter a service tools user ID and password. Press Enter.

Note that you need enough authority to run the Hardware service manager.

8. Type 1, Start a service tool. Press Enter.

9. Type 7, Hardware service manager. Press Enter.

10.Type 1, Packaging hardware resources. Press Enter.

11.Type 3, Concurrent Maintenance next to the System Expansion Unit with the same

Frame ID that you recorded in a previous step. Press Enter.

12.Press F9=Power off domain.

13.Enter to confirm.

14.You see a message that power off completed, but it may take a couple of minutes for the

xSeries to power down (the power light starts blinking). You may also see a break

message on the screen or in the QSYSOPR message queue that A critical system

hardware problem has occurred. You can ignore this message.

15.Remove the power cords from the xSeries.

16.Remove the HSL cables from the Integrated xSeries Adapter.

17.Remove the SPCN cable from the Integrated xSeries Adapter.

18.The xSeries can now be serviced and power cords reconnected if required.

19.After repairs are completed, make sure you clear the xSeries logs, save the settings, and

exit. Let the xSeries reboot to the install diskette screen.

20.Press the power button on the front panel to power off the xSeries.

21.Remove the power cords from the xSeries.

22.After you have removed the power cords, reconnect the HSL cables to the Integrated

xSeries Adapter.

23.Reconnect the SPCN cable to the Integrated xSeries Adapter. Make sure that all cables

are tight.

24.Reconnect the RS485 cable (if removed).

25.Reconnect the power cables.

26.The SPCN connection from the iSeries powers on the xSeries when it recognizes that the

Integrated xSeries Adapter is connected. The power light stops blinking. This may take a

few minutes. If you see the install diskette screen again, wait a few more minutes for the

xSeries to reboot. You should see a blinking cursor in the top left hand corner of the

xSeries console. If you do not, then additional problem determination is required. Note that

you may need to wait up to thirty minutes for the Integrated xSeries Adapter to be fully

recognized by the system, and the blinking cursor to appear.

27.At this point the Integrated xSeries Adapter should be operational. Enter the

WRKHDWRSC *CMN command and scroll down to the 2689 resource that you have been

maintaining. All resource levels should be “Operational”. Once this occurs the integrated

xSeries is ready for use.

Attention: Do not power on the xSeries using the xSeries power switch and do not use

the F10=Power on domain option of Hardware Service Manager.
