For more information about managed system states, see Managed System Operating States.

Creating Logical Partitions

  1. In the Contents area, select the managed system.
  2. From the selected menu, select Create.
  3. Select Logical Partition. The Create Logical Partition and Profile wizard opens.
  4. 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.
  5. Click Next.
  6. Type the name of the profile you are creating for this partition.
  7. Click Next.
  8. 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.

  9. Click Next.
  10. 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.

  11. Click Next.
  12. 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.
  13. 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.

  14. 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.

  15. Click Next. This window supplies you with summary information about this partition.
  16. Review the information to ensure that you have the appropriate resources assigned to this partition.
  17. If you want to change the configuration, click Back. Otherwise, click Finish to create the partition and profile.
  18. 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.

Creating Affinity Partitions

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:

  1. In the Contents area, select the managed system.
  2. From the selected menu, select Affinity Logical Partition.
  3. Select Create to open the Affinity Partition Setup wizard.
  4. In the first window of the Create Affinity Partition wizard, select the type of affinity partition you want to create.
  5. Click OK.
  6. 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.

  7. Click Next.
  8. 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.
  9. 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.

  10. Perform steps 6-9 for each affinity partition tab shown at the top of the screen.
  11. If you want to change the configuration for any affinity partition, click Back. Otherwise, click Finish to create the group of affinity partitions.
  12. 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.
  13. 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.

Updating Affinity Partitions After Adding or Removing Managed System Resources

To update affinity partitions after adding or removing managed system resources, do the following:

  1. In the Contents area, select the managed system.
  2. From the selected menu, select Affinity Logical Partition.
  3. Select Update.
  4. 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.

Activating 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'..

  4. After confirming that the affinity partitions listed are the ones you want to remove, click OK. The affinity partitions are removed from the Contents area.

Restarting the Operating System

When a partition is running an operating system and the system hangs, use the HMC to restart the operating system.

Attention: This operation can corrupt data. Perform this procedure only after you have attempted to restart the operating system manually.

Soft and Hard Resets

You can perform either a "hard" and "soft" reset.

To restart the operating system, you must be a member of one of the following roles:

To restart the operating system you have installed on a partition, do the following:

  1. In the Contents area, select the partition you want to reset.
  2. In the menu, click Selected.
  3. Select Operating System Reset.
  4. Decide if you want a hard or soft reset. Select the appropriate check box and click Yes.

Managing Partition Profiles

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.

Creating Additional Partition Profiles

To create partition profiles, you must be a member of one of the following roles:

To create a partition profile, do the following:

  1. 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.
  2. In the menu, click Selected.
  3. Select Create.
  4. 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.

Viewing Partition Profile Properties

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:

  1. In the Contents area, select the profile.
  2. In the menu, click Selected.
  3. Select Properties.

Setting Service Authority

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:

To set service authority, do the following:

  1. In the Contents area, select the profile.
  2. In the menu, click Selected.
  3. Select Properties to open the Properties window.
  4. Click the Other tab.
  5. Click Set Service Authority.
  6. Click OK.

Copying Partition Profiles

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:

To copy a partition profile, do the following:

  1. In the Contents area, select the existing profile that you want to copy.
  2. In the menu, click Selected.
  3. Select Copy.
  4. Type a unique name for the new copy.
  5. Click OK.

Changing Default Partition Profiles

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:

To change the default partition profile, do the following:

  1. In the Contents area, select the default partition profile that you want to change.
  2. In the menu, click Selected.
  3. Select Change Default Profile.
  4. Select the profile that you want to make the default profile from the list.

Understanding Partition Boot Errors

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:

To review a partition boot error, do the following:

  1. In the Contents area, right-click the partition that is in the Error state.
  2. Select Read Boot Error Value. A window opens that gives you more information about why the boot failed.

Deleting Partition Profiles

To delete partition profiles, you must be a member of the System Administrator role.

To delete a partition profile, do the following:

  1. 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.
  2. In the menu, click Selected.
  3. Select Delete.

Managing System Profiles

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.

Note:
This validation is approximate, and depends on which part of the memory block is being allocated to the current running partitions.

Activating System Profiles When Other Partition Profiles Are Running

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.

Powering On Using a System Profile

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.
