a) Remove power from the system. For details, see Stopping a system or logical partition
(http://publib.boulder.ibm.com/infocenter/systems/scope/hw/topic/p7haj/
crustopsys.htm).
b)
Go to step 6b5 on page 13.
v
If you are connecting your expansion units to a new system being installed, continue with
step 6b5 on page 13.
2) Verify the existing 12X configuration. If problems with the 12X loops are discovered in this
step, they must be corrected before continuing with this procedure. Follow the appropriate
step to determine if there are problems with the 12X configuration.
v If your system is managed by a Hardware Management Console (HMC) or Systems
Director Management Console (SDMC), see Verifying the 12X loops with an HMC or
SDMC (http://publib.boulder.ibm.com/infocenter/systems/scope/hw/topic/p7ham/
ipham_verifyriohslloopwhmc.htm). One of the steps in that task is to verify the status of
the links in the 12X loops. When you are instructed to use the
View Hardware Topology
task on the HMC, you can use the Save button to save the current hardware topology. This
action allows you to compare the topology that existed before the expansion units were
added with the topology that was created by adding the expansion units.
v
If your system is not managed by an HMC or SDMC, see Verifying the 12X loops without
an HMC or SDMC (http://publib.boulder.ibm.com/infocenter/systems/scope/hw/topic/
p7ham/ipham_verifyriohslloopwohmc.htm).
3) Verify the existing system power control network (SPCN). For details, see Verifying the
system power control network (http://publib.boulder.ibm.com/infocenter/systems/scope/
hw/topic/p7ham/verifyspcn.htm). If you discover a problem with the SPCN, you must
correct the problem before continuing.
4)
Set the SPCN Firmware Update Policy to prevent firmware updates over the serial SPCN
interface.
The SPCN Firmware Update Policy controls when and how SPCN firmware on expansion
units is updated. The default setting for the SPCN Firmware Update Policy is
Enabled
. This
setting allows for firmware updates to be completed over the 12X interface whenever an
update is required and does not allow updates over the slower serial SPCN interface.
a) Access the Advanced System Management Interface (ASMI) using an authority level of
administrator or authorized service provider. For details on using the ASMI, see
Managing the Advanced System Management Interface (http://publib.boulder.ibm.com/
infocenter/systems/scope/hw/topic/p7hby/asmi.htm).
b)
In the ASMI navigation area, expand
System Configuration
and select
Configure I/O
Enclosures
.
v
If the SPCN Firmware Update Policy shows
Expanded
, record the current setting so you
can restore it later. Then change the setting to
Enabled
.
v
If the SPCN Firmware Update Policy shows
Enabled
or
Disabled
, continue without
changing the setting.
c) Verify that no SPCN firmware updates are in progress by checking the Power Control
Network Firmware Update Status column. This column shows
In Progress and a percent
complete if an SPCN firmware update is in progress.
If an SPCN firmware update is in progress, check the Power Control Network Firmware
Update Status column to determine the type of update. Then choose one of the following
actions:
v
If the SPCN firmware update is an High Speed Link (HSL) update, wait for the update
to complete before continuing. An HSL update of the SPCN firmware completes
quickly.
v
If the SPCN firmware update is a serial update, either wait for the update to complete
or stop the update. A serial update of the SPCN firmware can take 20 minutes or more
depending on how many expansion units are in the configuration.
