Experiment name: Leveraging DPM on zHMC to Create, Modify and Delete the Host Partitions of IBM LinuxONE DPM

Experiment content:
Dynamic Partition Manager (DPM) is an application in zHMC, and this application can help you to manage and configure the Linux environment running on LinuxONE. This experience will guide you to experience how to leverage DPM to create, modify and delete the logic partitions (LPAR) on LinuxONE.

Leveraging DPM on zHMC to Create, Modify and Delete the Host Partitions of IBM LinuxONE DPM

The following content is displayed on the same screen for your experiment so that you can make any necessary reference in experiment. Start your experiment now!

  1. Log onto the zHMC Management Interface(Duration: 3 min)
    In the Firefox browser, click LOGIN to log onto zHMC.
  2. Create a new LPAR(Duration: 5 min)
    1) Click the menu System Management > BZ05 at the left, and you will see the system name and all the LPARs in the system. In this experiment, the host name is "BZ05". See the figure below for details:

    2) At the lower right corner, click +Configuration to open it as shown below:

    3) Click the option New Partition for creating a new LPAR, and the system will run an intelligent wizard to guide you on setting up the new LPAR. See the figure below for details:

    Before going to the next step, you should define the specific parameters of the LPAR to be created by completing all the information of LPAR as prompted in the intelligent wizard, then click Next.
    - Name: the name of LPAR; for ease of maintenance, we name it in the form of TMP-????, where ? is the initials of your name plus ID, e.g. TMP-Tony01.
    - Processors: the number of CPUs, e.g. 2.
    - Memory: memory/max. memory, e.g. 16 GB / 32 GB.
    - Network: click + at the upper left corner to add a network adapter to enter the menu "Next".
    Name: type the name of network adapter here, e.g. NIC001.
    Adapter Ports and Switch: select the information of the OSA card used; in this case, we select "OSD 0110 A13B-06" or "OSD 0170 A13B-35".
    Return back to the previous menu, check the network adapter just created, e.g. NIC001.
    - Storage: click + at the upper left corner to add a HBA card to enter the menu "Next".
    Name: type the name of HBA card, e.g. HBA001.
    Adapter Port: select the information of FC card; in this case, we select "FCP 0118 A13B-08" or "FCP 0119 A13B-08".
    Return back to the previous menu, check the HBA card just created, e.g. HBA001.
    - Boot: select None because it is impossible to obtain the WWPN of HBA card before creating LPAR.
    After the intelligent wizard ends, click Finish in the tab Summary, as shown in the figure below:

    Tips: After the LPAR is created, the WWPN of its HBA card can be exported through the option "Export WWPNs", or you may search it in the option "LPAR properties".
  3. Modify LPAR parameters(Duration: 3 min)
    1) In the page Home > System Management > BZ05, click the LPAR just created, e.g. TMP-Tony01, as shown in the figure below:

    2) Open the dialog box "Partition Details", and you may modify any parameter of the LPAR, as shown in the figure below:

    Once the modifications are completed, click "OK" or "Apply" to confirm such modifications.
  4. Delete the LPAR (Be cautious here to avoid wrongly deleting any other LPAR)(Duration: 6 min)
    1) In the page System Management > BZ05 under the page Home, select the LPAR just created, e.g. TMP-Tony01, and then select Delete Partition in the tap Configuration after clicking the arrow that follows it, as shown in the figure below:

    2) After re-confirming, click Delete at the lower right corner to delete the LPAR, and then click Close when a prompt message pops up.
