Logical Partition creation

For implementation guidance about creating LPARs, refer to the IBM Redbooks publication LPAR Simplification Tools Handbook, SG24-7231.

Plan your layout...

If we plan to use a virtual device, install the virtual device and the VIO Server before creating the partition.

To create a logical partition...

  1. Log on to the HMC Console View

  2. In the Contents area, select the managed system.

  3. From the Selected menu, select Create.

  4. Select Logical Partition. The Create Logical Partition Wizard opens...

  5. 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 in length...

  6. Click Next.

  7. Select the desired, minimum, and maximum number of processors you want for this partition profile.

  8. Click Next.

  9. Select the desired and minimum number of memory...

  10. Click Next.

  11. The left side of the new window displays the I/O drawers available and configured for use.

    Expand the I/O tree to show the individual slots in each drawer. Because the HMC groups some slots, if we 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.

    Select 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.

  12. Select the slot you want to assign to this partition profile and click either required or desired. If we want to add another slot, repeat this process.

    The slots in the I/O drawers field are not listed in sequential order.

    Slots are added individually to the profile; you can add slots one at a time, unless they are grouped. Minimally, assign a boot device to the required list box. This might be real or virtual depending on the choice of your server.

    There are two groups to which you can add adapters:

    • desired group
    • required 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. Click Next.

  13. This window enables you to set service authority and boot mode policies for this partition profile. Select the boot mode that you want for this partition profile...

  14. Click Next.

  15. 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 we 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, appears under the Managed System tree in the Contents area. After you have created a partition, install an operating system and configure inventory data collection on the HMC and on the partition.
