see Managed System Operating States.
- In the Contents area, select the managed system.
- From the selected menu, select Create.
- Select Logical Partition. The Create Logical Partition
and Profile wizard opens.
- In the first window of the Create Logical Partition and Profile wizard,
provide a name for the partition profile that you are creating. Use a
unique name for each partition that you create. Names can be up to 31
characters long.
- Click Next.
- Type the name of the profile you are creating for this partition.
- Click Next.
- Select the desired, minimum, and maximum number of processors you want for
this partition profile. The HMC shows you the total number of
processors configured for use by the system, and prompts you to enter your
desired, minimum and maximum processor
amounts for this partition profile. The following is a description of
each term:
- Desired
- Desired amounts are used if they are available at the time of
activation.
- Minimum
- Minimum amounts define the processors you require for this
partition. If these processors are not available at the time you
attempt to activate the profile, the partition does not activate.
- Maximum
- Maximum amounts define the largest number of processors you can assign to
this partition. If you attempt to dynamically move an amount of
processors to this partition that exceeds this number, an error message
displays, and the operation stops.
- Click Next.
- Select the desired and minimum number of memory. The HMC shows you
the total amount of memory configured for use by the system, and not the
amount that is currently available. The HMC prompts you to enter your
desired, minimum and maximum memory amounts
for this partition profile. The following is a description of each
term:
- Desired
- Desired amounts are used if they are available at the time of
activation.
- Minimum
- Minimum amounts define the memory amount you require for this
partition. If this memory amount is not available at the time you
attempt to activate the profile, the partition does not activate.
- Maximum
- Maximum amounts define the largest amount of memory you can assign to this
partition. If you attempt to dynamically move an amount of memory to
this partition that exceeds this number, an error message displays and the
operation stops.
Enter the amount of desired and required memory in 1 gigabyte (GB)
increments and 256 megabyte (MB) increments. You must have a minimum of
1 GB for each partition.
Some special memory issues must be considered when you assign memory
to partitions. For more information about these memory issues, see Memory.
- Click Next.
- The left side of the new window displays the I/O drawers available and
configured for use. To expand the I/O tree to show the individual slots
in each drawer, click the icon next to each drawer. Because the HMC
groups some slots, if you attempt to assign a member of one of these "grouped"
slots to a profile, the entire group is automatically assigned. Groups
are indicated by a special icon named Group_XXX.
Click on the slot for details about the adapter installed in that
slot. When you select a slot, the field underneath the I/O drawer tree
lists the slot's class code and physical location code.
- Note:
- The slots in the I/O Drawers field are not listed in sequential order.
- Select the slot you want to assign to this partition profile and click
Add. If you want to add another slot, repeat this
process. Slots are added individually to the profile; you can add
slots one at a time, unless they are grouped. Minimally, add a boot
device to the required list box.
There are two groups to which you can add adapters: a
Required and a Desired group. Desired adapters
will be used if they are available at the time of activation. Required
adapters are adapters that you require for this partition. If the
adapters in this group are not available at the time of activation, the
partition does not activate.
If you want to install an operating system on this partition using
the managed system's CD-ROM drive, assign the CD-ROM to this partition
profile.
- Click Next. This window allows you to set service
authority and boot mode policies for this partition profile.
If you want this partition to be used by service representatives to perform
system firmware updates and set other system policy parameters, select the
Set Service Authority check box.
Select the boot mode that you want for this partition
profile. For a description of each boot mode, see Power-On Options.
- Click Next. This window supplies you with summary
information about this partition.
- Review the information to ensure that you have the appropriate resources
assigned to this partition.
- If you want to change the configuration, click Back.
Otherwise, click Finish to create the partition and profile.
- The new partition, along with the default profile you just created,
displays underneath the Managed System tree in the Contents area.
After you have created a partition, you must install an operating
system and configure Inventory Scout Services on the HMC and on the
partition. To install an operating system on the partition and
configure Inventory Scout Services on that partition, refer to the
installation information shipped with your operating system. To
configure Inventory Scout Services for this partition on the HMC, see FORM='TEXTONLY'..
- Note:
- If you want to use the managed system's CD-ROM to install
operating systems on your partitions, it is recommended that you create at
least two profiles for each partition. Create one profile that has the
managed system's CD-ROM assigned to it, and another profile without the
managed system's CD-ROM. Using this method, you can release the
managed system's CD-ROM by deactivating the profile that has the CD-ROM
and activating the profile that does not have the CD-ROM. For more
information about creating partition profiles, see Creating Additional Partition Profiles.
Depending on your managed system's configuration, you may be able to
create a special group of logical partitions called affinity
partitions. The process of creating a group of affinity
partitions is similar to the process of creating logical partitions.
The only difference is that the system does the processor and memory
assignment for you.
To determine if your managed system is capable of running affinity
partitions, check your managed system's properties. For more
information about viewing your managed system's properties, see Viewing Managed System Properties.
To create an affinity partition, do the following:
- In the Contents area, select the managed system.
- From the selected menu, select Affinity Logical
Partition.
- Select Create to open the Affinity Partition Setup
wizard.
- In the first window of the Create Affinity Partition wizard, select the
type of affinity partition you want to create.
- Click OK.
- In the second window of the Create Affinity Partition wizard, type a name
for the first affinity partition that you are creating. Use a unique
name that is up to 31 characters long.
In the second field, type a name for the default profile.
Then select which boot mode this affinity partition will use when you
activate it.
Select the Set Service Authority check box if you want this
partition to be used by service representatives to perform system-firmware
updates and set other system policy parameters.
Enter this information for each of the affinity partitions you want to
create. To select another affinity partition, click on the appropriate
ALPAR tab on the top of the window.
- Click Next.
- The left side of the new window now displays the I/O drawers available and
configured for use. To expand the I/O tree to show the individual slots
in each drawer, click the icon next to each drawer. Because the HMC
groups some slots, if you attempt to assign a member of one of these "grouped"
slots to a profile, the entire group is automatically assigned. Groups
are indicated by a special icon named Group_XXX.
Click on the slot for details about the adapter installed in that
slot. When you select a slot, the field underneath the I/O drawer tree
lists the slot's class code and physical location code.
- Note:
- The slots in the I/O Drawers field are not listed in sequential
order.
- Select the slot you want to assign to this default affinity profile and
click Add. If you want to add another slot, repeat this
process. Slots are added individually to the profile; you can only
add slots one at a time, unless they are grouped. Minimally, add a boot
device to the required list box.
If you want to install an operating system on this partition using
the managed system's CD-ROM drive, assign the CD-ROM to this partition
profile.
- Perform steps 6-9 for each affinity partition tab shown at the top of the
screen.
- If you want to change the configuration for any affinity partition, click
Back. Otherwise, click Finish to create the group
of affinity partitions.
- The new affinity partitions, along with the default profiles you just
created, display underneath the Managed System tree in the Contents
area. A System Profile is also created and is displayed underneath the
managed system tree.
- After you have created a partition, you must install an operating system
on the partition. To install an operating system on the partition,
refer to the installation information provided with your operating
system.
- Note:
- If you want to use the managed system's CD-ROM to install
operating systems on your partitions, it is recommended that you create at
least two profiles for each partition. Create one profile that has the
managed system's CD-ROM assigned to it, and another profile without the
managed system's CD-ROM. Using this method, you can release the
managed system's CD-ROM by deactivating the profile that has the CD-ROM
and activating the profile that does not have the CD-ROM. For more
information about creating partition profiles, see Creating Additional Partition Profiles.
To update affinity partitions after a service representative has added or
removed resources on the managed system, you must be a member of one of the
following roles:
- System Administrator
- Advanced Operator
To update affinity partitions after adding or removing managed system
resources, do the following:
- In the Contents area, select the managed system.
- From the selected menu, select Affinity Logical
Partition.
- Select Update.
- The HMC will then assess what resources have been added or removed, and
will ask you if you would like to add or remove affinity partitions as
appropriate. For more information about adding new affinity partitions,
see Creating Affinity Partitions. If you have removed resources from your managed
system, the HMC lists the affinity partitions associated with the removed
resources. Click OK to remove these affinity
partitions.
To activate a partition, select the partition itself, and click
Activate from the Selected menu. A window opens that lists
activation profiles. The default partition profile is automatically
highlighted, but you can activate the partition with any of the listed
profiles.
If the required resources you specified in the partition profile that you
are using to activate the partition exceed the amount of available resources,
this partition does not activate. All resources currently not being
used by active partitions are considered available resources. It is
important that you keep track of your system's resources at all
times.
For service, you must also configure Inventory Scout Services for each
partition you activate. For more information about configuring
Inventory Scout, see FORM='TEXTONLY'..
To activate partitions, you must be a member of one of the following
roles:
- Operator
- Advanced Operator
- System Administrator
- Service Representative
To activate a partition profile, do the following:
- In the Contents area, select a partition profile.
- On the menu, click Selected.
- Select Activate.
- The profile name is highlighted. Click OK to activate

check box and click Yes.
A partition profile defines the set of resources that you need to create a
partition. You can create more than one partition profile for a
partition, but you can activate only one partition profile for a
partition at a time.
When you create a partition profile, the HMC shows you all the resources
available on your system. The HMC does not, however, check to see if
another partition is currently using a portion of these resources. For
example, the HMC might show 16 processors on your system, but will not
indicate that other partitions are using nine of them. You can
conceivably create two partition profiles, each using a majority of system
resources. However, you can do this only if you do not intend to use
them at the same time. If you attempt to activate both of these
partition profiles, the second activation attempt will fail.
To create partition profiles, you must be a member of one of the following
roles:
- System Administrator
- Advanced Operator
To create a partition profile, do the following:
- In the Contents area, select the partition for which you want
to create a profile. If you select the managed system, you create a new
partition, not a profile.
- In the menu, click Selected.
- Select Create.
- Select Profile from the menu. A profile creation wizard
opens and guides you through the creation of a new profile.
You can now begin to assign resources to the new partition profile.
This partition profile does not take effect until you use it to activate the
partition.
You can view partition profile information from your HMC. Depending
on your access levels, you can also restore, back up, and remove this data
from the local file system.
Any user can view profile properties.
To view a partition profile's properties, do the following:
- In the Contents area, select the profile.
- In the menu, click Selected.
- Select Properties.
Service representatives use the partition designated with service authority
to perform system firmware updates. If you set service authority for
one partition, a service representative can use this partition to perform
system updates without having to power off the managed system.
To set service authority, you must be a member of one of the following
roles:
- Advanced Operator
- System Administrator
To set service authority, do the following:
- In the Contents area, select the profile.
- In the menu, click Selected.
- Select Properties to open the Properties window.
- Click the Other tab.
- Click Set Service Authority.
- Click OK.
The HMC allows you to copy the contents of a profile that you have already
created. For example, you might decide that you need a partition
profile that is similar to one that you have already created, but with a small
change in resource allocation.
To copy partition profiles, you must be a member of one of the following
roles:
- System Administrator
- Advanced Operator
- Service Representative
To copy a partition profile, do the following:
- In the Contents area, select the existing profile that you want to
copy.
- In the menu, click Selected.
- Select Copy.
- Type a unique name for the new copy.
- Click OK.
When you create a partition, the HMC requires that you create at least one
profile called the default profile. In the Contents area,
the default profile is represented by an icon that looks similar to the
following illustration:
When activating a partition, the HMC highlights the default profile as the
one to use during activation unless you specify that it activate a different
partition profile.
To change default profiles, you must be a member of one of the following
roles:
- System Administrator
- Advanced Operator
To change the default partition profile, do the following:
- In the Contents area, select the default partition profile that you want
to change.
- In the menu, click Selected.
- Select Change Default Profile.
- Select the profile that you want to make the default profile from the
list.
If a partition is in an error state after you attempted to activate it, you
can perform this task to determine the boot error value, which indicates why
the boot failed.
For more information about boot error values, see Boot Error Values.
To review a partition boot error, you must be a member of one of the
following roles:
- System Administrator
- Advanced Operator
- Service Representative
To review a partition boot error, do the following:
- In the Contents area, right-click the partition that is in the
Error state.
- Select Read Boot Error Value. A window opens that gives
you more information about why the boot failed.
To delete partition profiles, you must be a member of the System
Administrator role.
To delete a partition profile, do the following:
- In the Contents area, select the profile.
- Note:
- Be sure to select the profile and not the partition itself, to avoid deleting
an entire partition.
- In the menu, click Selected.
- Select Delete.
System profiles are a collection of one or more partition profiles.
When you activate a system profile, you also activate each associated
partition profile. You can use a system profile at any time, including
when you power on the managed system.
For more information about partition profiles, see Managing Partition Profiles.
To create system profiles, you must be a member of one of the following
roles:
- System Administrator
- Advanced Operator
To create a system profile, do the following:
- In the Contents area, select the managed system.
- On the menu, click Selected.
- Select Create.
- Select System Profile.
- Name the system profile and select the available partition profiles that
you want to add to the new system profile.
- Click Add for each selected partition profile. Pick one
profile per partition to place into a system profile.
- Click OK.
Any user can view system profile properties.
To view the properties of the system profile, do the following:
- In the Contents area, select the system profile.
- On the menu, click Selected.
- Select Properties.
To modify system profiles, you must be a member of one of the following

- In the Contents area, select the system profile you want to modify.
- On the menu, click Selected.
- Select Properties from the menu.
- Change the system profile information as appropriate.
Because some system profiles are complex, the HMC allows you to copy the
contents of a profile you have already created.
To copy system profiles, you must be a member of one of the following
roles:
- System Administrator
- Advanced Operator
To copy a system profile, do the following:
- In the Contents area, select the existing profile that you want to
copy.
- On the HMC menu, click Selected.
- Select Copy.
- In the Copy Profile window, type the new profile name.
- Click OK.
To delete a system profile, you must be a member of the System
Administrator role.
To remove a system profile, do the following:
- In the Contents area, select the system profile.
- On the menu, click Selected.
- Select Delete. The Delete System Profile
window opens. Click Yes to delete the profile.
To activate system profiles, you must be a member of one of the following
roles:
- System Administrator
- Advanced Operator
- Operator
- Service Representative
To activate a system profile, do the following:
- In the Contents area, select the system profile.
- On the menu, click Selected.
- Select Activate.
If one of the partition profiles in a system profile requires a resource
that is currently in use by the system or another partition, the system
profile does not activate.
To validate system profiles, you must be a member of one of the following
roles:
- System Administrator
- Advanced Operator
- Operator
- Service Representative
To ensure that a system profile will activate successfully, do the
following:
- In the Contents area, select the system profile.
- On the menu, click Selected.
- Select Validate.
If a situation exists that prevents the profile from activating
successfully, a window displays that provides you with the details.
- Note:
- This validation is approximate, and depends on which part of the memory block
is being allocated to the current running partitions.
To activate a system profile, shut down the operating system for any active
partition, so that the partition's state changes from Running
to Ready.
You can power on your managed system by using a predefined system
profile. To learn more about powering on using a system profile you
have already created, read System Profiles.
