The following comments apply to the IBM System i models and IBM System p servers that have been
designated as conforming to NEBS (Network Equipment-Building System) GR-1089-CORE:
The equipment is suitable for installation in the following:
v Network telecommunications facilities
v Locations where the NEC (National Electrical Code) applies
The intrabuilding ports of this equipment are suitable for connection to intrabuilding or unexposed
wiring or cabling only. The intrabuilding ports of this equipment must not be metallically connected to the
interfaces that connect to the OSP (outside plant) or its wiring. These interfaces are designed for use as
intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation
from the exposed OSP cabling. The addition of primary protectors is not sufficient protection to connect
these interfaces metallically to OSP wiring.
Note: All Ethernet cables must be shielded and grounded at both ends.
The ac-powered system does not require the use of an external surge protection device (SPD).
The dc-powered system employs an isolated DC return (DC-I) design. The DC battery return terminal
shall not be connected to the chassis or frame ground.

One of the bulk power assemblies (BPAs) contained in the frame is in the
process of starting. The state of the other BPA cannot be determined.
Standby/Standby
Both of the bulk power assemblies (BPAs) contained in the frame are in the
standby state. A BPA in the standby state is operating normally.
Standby/Starting
One of the bulk power assemblies (BPAs) contained in the frame is
operating normally (in standby state). The other BPA is in the process of
starting.
Standby/Not Available
One of the bulk power assemblies (BPAs) contained in the frame is
operating normally (in the standby state), but the other BPA is not operating
normally.
Pending frame number
A change to the frame number is in progress. No operations can be
performed when the frame is in this state.
Failed Authentication
The HMC access password for the frame is not valid. Enter a valid
password for the frame. See “Overview of passwords” on page 21 for more
information about the HMC access password.
Pending Authentication - Password
Updates Required
The frame access passwords have not been set. You must set the required
passwords for the frame, to enable secure authentication and access control
from the HMC. See “Overview of passwords” on page 21 for information
about setting the required passwords.
No Connection
The HMC cannot connect to the frame.
Incomplete
The HMC failed to get all of the necessary information from the managed
frame. The frame is not responding to requests for information. See
Correcting the managed system operating state.
Note: For information about the operational states of the managed systems contained in the frame, see
“Managed system states” on page 18.
Working with managed systems and frames
Learn how to perform actions on the HMC that pertain to the managed system.
You can use the HMC to communicate with the managed systems and frames in your environment. For
example, you can use power-on options to start and shut down your managed systems, and to monitor
system states.
Use the information in this topic to learn more about the tasks that you can perform using the HMC to
work with the managed system and frames.

Powering on and off a managed system
Read about how to use the HMC to power on and off a managed system. Also find information about
scheduling managed-system power operations.
You can use the HMC to control the power on a managed system. The following tasks describe these
activities:
Note: For information about the power-on states that display for managed systems in the HMC, see
“Managed system states” on page 18.
Powering on a managed system:
Understand how to power on a managed system using the HMC.
You can use the HMC to power on a managed system and to monitor the power-on state.
To power on a managed system, you must be a member of one of the following roles:
v super administrator
v service representative
v operator
v product engineer
To power on a managed system, complete the following steps:
1.
2.
3.
4.
In the Navigation area, expand the Server and Partition folder.
Click the Server Management icon.
In the Contents area, select the managed system.
From the menu, click Selected → Power On.
5. Select the desired power-on mode and click OK.
For more information about each power-on mode, see “Managed system power-on and power-off modes”
on page 17.
Powering off a managed system:
Understand how to use the HMC to power off a managed system.
By default, the managed system is set to power off automatically when you shut down the last running
logical partition on the managed system. If you set the managed system properties on the HMC so that
the managed system does not power off automatically, you must use this procedure to power off your
managed system.
Attention: If possible, shut down the running logical partitions on the managed system before powering
off the managed system. Powering off the managed system without shutting down the logical partitions
first causes the logical partitions to shut down abnormally and can cause data loss.
For more information about shutting down your logical partitions, see the following topics:
v Shutting down AIX
v Shutting down i5/OS
v Shutting down Linux
To power off a managed system, you must be a member of one of the following roles:

Overview of passwords:
Managing your server, adapters, and devices
21
Describes the passwords that you need in order to access a managed system using your HMC.
The first time you access a managed system using an HMC, the system prompts you to enter passwords
for each of the following:
v Hardware Management Console: HMC access
v Advanced System Management Interface: General
v Advanced System Management Interface: Admin
If all required passwords are not set, the state of the managed system displays Pending Authentication –
Password Updates Required until these passwords are set.
To change the managed system’s password, see “Changing the managed system’s password.”
If you are using an HMC to access the managed system before all required passwords have been set,
enter the appropriate password for each password that is presented in the Update Password Pending
Authentication window. If another HMC subsequently needs access to this managed system, upon
attempting to access this HMC the user is presented with the Update Password Failed Authentication
window, which will prompt for the HMC access password you entered.
In the event that the HMC access password changes while you are logged in to the managed system,
your HMC will discover that it can no longer authenticate after it attempts to reconnect to that managed
system. This will result in a state of Failed Authentication for that managed system. You will be required to
enter the new password before any actions can be performed.
For more information about the Advanced System Management Interface (ASMI), see Managing your
server using the Advanced System Management Interface.
Changing the managed system’s password:
Update a managed system’s password using the HMC.
You can use the HMC interface to change a managed system’s HMC access password. If you change this
password, you must change the password for any other HMCs that connect to this managed system.
The super administrator user role is required to change this password.
To change the managed system’s HMC access password, complete the following steps:
1. In the Navigation area, expand the Server and Partition folder.
2. In the Navigation area, click the Server Management application icon.
3. In the Contents area, right-click the managed system and then select Update Managed System

Setting huge-page memory values
Specify the number of 16-GB pages to allocate to a huge-page memory pool.
On managed systems that support huge-page memory, you can use the Hardware Management Console
(HMC) to set the value for the huge-page memory pool. You can also specify values for the number of
huge pages to allocate to logical partitions.
Managing your server, adapters, and devices
23
Using huge pages can improve performance in specific environments that require a high degree of
parallelism, such as in DB2® partitioned database environments. You can specify huge-page memory that
can be used for the shared-memory buffer pools in DB2. For logically partitioned systems, you can
specify the minimum, desired, and maximum number of huge pages to assign to a partition when you
create the partition or partition profile. See Creating logical partitions and partition profiles.
To set the huge-page memory values, the system must be in the powered-off state. The new value will
take effect when you restart the system.
Use the following information to determine the requirements and appropriate values for your specific
application, and to set the huge-page values.
Calculating huge-page memory requirements:
Calculate the value for the number of pages to allocate to a huge-page memory pool.
To use huge-page memory, you must ensure that your system has adequate memory resources to
dedicate to the huge-page memory pool. The huge-page memory pool is a region of system memory that
is mapped as 16-GB page segments and is managed separately from the system’s base memory. Before
you can specify the value for huge-page memory, you must determine which applications you are
running and what the huge-page requirements are for your applications.
Determining huge-page memory requirements for your application
The huge-page memory pool can be used to enhance performance for DB2 partitioned database
environments in AIX operating systems. For DB2 applications, you would typically use huge pages for
large DB2 multipartitioned database environments to efficiently support the degree of parallel activity
required of shared memory buffer pools. To determine this value, calculate the amount of memory
required for the shared buffer pool to support your DB2 applications. Refer to the DB2 recommendations
for buffer pool memory for your particular application.
In logically partitioned systems, you can assign huge-page memory when you create the partitions. This
value is separate from the value that you specify for the configured-partition memory region. You can
specify a minimum, desired, and maximum value. To determine the number of huge pages needed for
your logical partitions, see the section below that discusses calculating huge page values.
Note: The huge page memory allocation cannot be changed dynamically. Changing the number of huge
pages on the server requires a server reboot, and changing the number of assigned huge pages for a
partition requires a partition reboot.
Considerations for calculating the huge page values
The amount of huge-page memory that you can allocate is dependent on the following factors:
v Total amount of licensed memory for your server
v Amount of available memory after configured memory resources are accounted for
v Number of physical IO connections to the server (each IO connection requires memory for the IO
tables, which can be distributed among the physical memory regions and reduces the memory
available for huge pages)
v Base memory configuration for logical partitions (huge pages are not calculated as part of the
configured-partition memory allocation)
v The requirements that define a huge page, that is each huge page requires 16 GB of contiguous real
memory and must start on a 16-GB memory boundary
v Huge pages cannot span memory affinity nodes. Each memory affinity node requires 32 GB to ensure
at least one 16 GB huge page when all of the other considerations listed above are taken into account.
24
System i and System p: Managing your server using the Hardware Management Console
Note:
1. For the 9133-52A, 9133-55A, 9116-561, 9406-550, 9406-570, and 9117-570 a physical processors card is
a memory affinity node, so the 32 GB must be put on a single 2-way processor card.
2. For the 9119-590, 9119-595, and 9406-595 each 4-way processor on the 16-way processor backplane is
a memory affinity node, so the 32 GB must be put into the slots on the same 4-way processor on
the backplane.
Attention: The server firmware will reduce the huge-page pool size to satisfy some of these
dependencies. When this occurs, error log entries are generated to indicate that the huge-page pool size
was reduced. The error log reference code is B700 5300. The reference code details will indicate
hexadecimal values that indicate why the huge-page pool size could not be satisfied. The following
example shows the possible entries and how to interpret the additional words in these entries:
v word 3 = 0x0000000100000106 - huge page pool reduced to satisfy system hardware configuration
– word 4 = number of user-configured huge pages
– word 5 = number of huge pages that could be provided
v word 3 = 0x0000000100000105 - huge page pool reduced to satisfy the memory configuration of
partitions
– word 4 = number of huge pages before partitions were created
– word 5 = firmware calculated number of huge pages after satisfying partition memory requirements
– word 6 = number of huge pages in the pool
Calculating huge-page memory values
To calculate the server memory requirements to support huge pages, use the following steps:
1. Determine the amount of base system memory and round that figure to the next 16-GB value. To
determine the base server memory requirements, which includes the POWER® hypervisor and
partition, but not huge pages, use the LPAR Validation tool (LVT) or System Planning Tool. See
Planning for logical partitions for information about using these planning tools.
2. Determine the number of IO connection loops on your system and multiply the number by 16 GB.
This calculation is required because the server needs a memory table for each IO connection, and a
16-GB huge page cannot be located where an IO table exists.
3. Take the larger of the values determined in step 1 and step 2. This will be your base memory value.
4. Determine the number of huge pages that will be required for your AIX applications. To determine
this value, use the guidelines provided by your application documentation and the AIX Performance
Management Guide. Multiply the number of anticipated huge pages by 16 GB. Add this figure to the
base figure determined in step 3. The resulting figure provides an estimate of the amount of licensed
memory required to satisfy partition and huge-page pool memory requirements for your system.
Viewing and setting huge page memory values:
View and set values for huge-page memory allocation.
On systems that support huge-page (16 GB) memory allocation, you can view and set the current value
in the huge-page memory table. On a new system you must set this value initially to establish the
huge-page memory pool. You must set the value when the managed system is in the powered-off state. If
this value is already set, you might need to change the value to adjust for performance needs based on
the applications that you are running and your partitioning configurations. You can also change the
values set for the number of huge pages allocated to your logical partitions.
Use this task to view huge-page values and to set or adjust the number of 16-GB pages for the huge-page
allocation according to your needs. Before setting a value, review the information in “Calculating
huge-page memory requirements” on page 24.

The HMC displays the system’s name, logical partition capability, state, serial number, model and type,
and policy information. A system that is powered on using the Partition Standby option displays this
information, as well as available and assigned processors, memory, I/O drawers and slots, power-on
parameters, reference codes, and policy information. The HMC also displays power-on parameters and
reference codes for a managed system in the power-off state.
The Processor tab displays information that is helpful when performing Dynamic Logical Partitioning
processor tasks. Use the Processor tab to view processor usage data for partitions and determine whether
a processor is assigned to a logical partition. The information in the Processor tab is also helpful when
you need to know if processors are disabled and therefore cannot be used by any logical partition.
The Memory tab shows deconfigured resources, as well as information about available and configured
memory. To view or change memory allocation on systems with huge page table support, use the
Memory tab and select Show details in the Advanced Options area. To change the requested value for
huge page memory, the system must be powered off.
The information provided in the memory tab (for example, deconfigured resources), along with the
information provided on the I/O tab, is useful for planning for processors and dynamic logical partitions.
Updating managed system or frame information:
Update the system information for a managed system or frame in the HMC that is in an Incomplete state.
Updating, or rebuilding a managed system or frame acts much like a refresh of the managed system or
frame information. Rebuilding the managed system or frame is useful when the system’s state indicator
in the contents area of the HMC GUI is shown as Incomplete. The Incomplete indicator signifies that the
HMC cannot gather complete logical partition, profile, or resource information from the managed system.
This operation is different from performing a refresh of the local HMC panel. When the managed system
is updated, the HMC reloads information stored on the managed system.

Disconnecting another HMC connection:
Read about how to manually unlock an HMC locked connection to the managed system.
If you have two HMCs connected to the managed system, one HMC temporarily locks the other out
while it is performing operations. This action prevents the other HMC from operating on the managed
system because simultaneous operations could cause conflicting results. If the interface is locked, most
console operations automatically wait for the lock to release.
However, in the rare event that an HMC has a problem that prevents the lock from being properly
released, you need to manually disconnect the connection to the managed system. Typically, if one HMC
has locked the connection, you must unlock it from the other HMC, which then allows other HMCs to
communicate with the managed system and run further commands.
To release a lock on a managed system requires the super administrator role.
To unlock an HMC connection, complete the following steps:
1. In the Contents area, select the managed system.
2. In the menu, click Selected.
3. Select Disconnect another HMC. The Disconnect Another HMC window opens.
4. From the list, select the HMC that you want to disconnect, and then click OK.
Recovering partition data on a managed system:
Learn how to recover the partition data on your managed system if it becomes corrupted.
Through the HMC interface, you can recover partition data on your managed system if the data becomes
damaged. This partition data includes information about logical partitions, partition profiles, and system
profiles. If the partition data on your managed system becomes damaged, the managed system is in
recovery state. You can either restore the partition data from a backup file that is saved automatically on
your HMC by selecting Restore profile data from the HMC backup data, or clear all partition
configuration with Initialize the managed system.
This procedure recovers the partition data in the service processor of your server. To recover the partition
data on your managed system, see Restoring profile data.

Managing frames using the HMC
Learn about the tasks that you can use to manage your frames in the HMC.
This topic describes how to perform various tasks related to managing your frame that is connected to
the HMC.
Adding a frame:
Use this procedure to add a frame manually to the HMC.
New frames are automatically detected, or discovered, by the HMC when the HMC is configured as a
DHCP server. For information about configuring your HMC as a DHCP server, see The HMC as a DHCP
server. Upon detection of a new frame, the DHCP server assigns an IP address to the frame. This newly
assigned IP address remains static as long as the MAC address remains unchanged. When a frame is
replaced, the DHCP server assigns a new IP address and broadcasts an update to all HMCs on the
network.
Note: Add a frame by configuring your HMC to automatically detect new frames. Use the instructions
provided at the link referenced in the preceding paragraph.
In addition to adding a frame automatically, the HMC allows you to manually add frames to the
managed frames of this HMC. You will need to provide the host name and IP address for each frame that
you want to add. You can also find a frame on the network within a specified IP address range. The
discovery processing time can vary depending on the range of IP addresses that you entered and your
network configuration.
To add a frame, you must be a member of one of the following roles:
v super administrator
v operator

System i and System p: Managing your server using the Hardware Management Console
Adding managed systems to the HMC environment
Understand how to add managed systems to the HMC, so that you can manage them using the HMC
interface.
You can manage multiple systems from a Hardware Management Console (HMC). To add a managed
system to the HMC, you must establish a network connection between the HMC and the service
processor of the new system. Configuring the HMC to work with the new managed system depends on
how you have set up and configured the existing network connections between the HMC and the
already-installed managed systems, including connections to the logical partitions.
For more information about configuring network connections on the HMC, see HMC network
connections.
Use the following topics to determine how to add a managed system to your HMC environment based
on your existing network configuration. After completing the HMC connection, add the system to your
HMC environment by selecting the managed system connection in the HMC GUI and selecting Add
managed system from the Selected menu. Follow the instructions in the Add managed system window
by specifying the name or IP address of the managed system or specifying a range of IP addresses to find

Use a dedicated private network that you already have set up with the HMC acting as a DHCP server to
manage your system.
If your existing network is already set up as a ″private″ dedicated network with the HMC acting as a
DHCP server, then you must physically connect to the new system. For more information about
physically connecting to a new managed system, see Setting up the Hardware Management Console. If
you have an Ethernet switch with available ports connected to the HMC, connect the Ethernet cable from
the service processor of the new system to the Ethernet switch. When the connection is made, the HMC
automatically detects the managed system and adds it to the Contents area of the HMC interface.
Automatic detection does not occur if you removed the managed system prior to its availability.
Using an existing open network:
Understand the requirements for using the HMC in a configured open network.
If the HMC was connected to existing managed systems over an ″open″ (public) network, other types of
devices and systems can exist on the network. More specifically, the HMC is not acting as a DHCP server.
In this environment, you must take one of the following actions to use the HMC:
v Manually configure the new managed system’s service processor with a static (fixed) set of IP
parameters using the Advanced System Management Interface.
v Manually configure the IP address of the new system’s service processor, if there is an existing DHCP
server on the network.
When the connection is made, you can add the managed system by using the Add managed systems
function or the mksysconn command.
Deleting a managed system
Disconnect a managed system from the HMC before you physically detach it from the HMC.
If you no longer want to manage a particular system, you can delete it from the Contents area of the
HMC GUI.
Managing your server, adapters, and devices
33
Note: You must delete the managed system from the Contents area before you disconnect the Ethernet or
the network-attached cable from the hardware.
To delete the managed system from the Contents area, you must be a member of the super administrator
role.
To delete the managed system from the Contents area, complete the following steps:
1. In the Contents area, select the managed system.
2. From the menu, click Selected.
3. Select Reset or Remove Connection from the menu.
4. Click remove, then click OK.
After the managed system’s logical connection is removed, you can remove the managed system from the
network.
Moving the managed system from an open network to a private network
Learn how to move a managed system that is attached to an HMC on an open network to an HMC that
is located on a private network.
You can move a managed system from an open network to a private network. It is recommended that
you configure the HMC that is located on the private network as a DHCP server before you attach the
new managed system. This configuration will allow the HMC to automatically detect the newly added
managed system and assign it a unique IP address.
To perform this operation, you must be a member of one of the following roles:
v super administrator
v service representative
v product engineer
To move the managed system from an open network to a private network, complete the following steps:
1. Configure the HMC that is located on the private network as a DHCP server. For more information,
see Configuring the HMC as a DHCP server.
2. Remove the static IP address of the managed system that you want to move using the Advanced
System Management Interface (ASMI). For more information about how to use ASMI to configure the
HMC as a DHCP server, see Configuring network interfaces.
3. Disconnect the cable of the managed system that you want to move from the HMC that is located on
the open network.
4. Connect the cable of the managed system to the HMC located on the private network. Because you
previously configured the HMC that is located on the private network as a DHCP server, the newly
attached managed system is automatically detected and assigned a new IP address.
Servicing the managed system
Understand how you can use the HMC to perform service actions.
The Customer service, support, and troubleshooting topic provides an overview of the elements of the
service and support environment. It also describes the different functions and features of the environment
and the HMC applications that provide those functions.
Using the IBM Network Manager
Learn how to use the IBM Network Manager to manage InfiniBand networks.
The IBM Network Manager enables you to manage your InfiniBand network from the Hardware
Management Console (HMC).
34
System i and System p: Managing your server using the Hardware Management Console
Use the IBM Network Manager to manage IB switches, update switch software, view network topology
information, and view and modify management properties. You must enable the Network Manager from
