Enabling a Partition Image

Enabling is a process in which the allocated resources are reassigned to the partition image and it is brought to the stopped state and can be started. This process also allows you to make changes to the resources associated with the partition image such as processor, number of cores, ports, and memory. Once the partition image is enabled, the assigned hardware resources are unavailable for other chassis.

Notes:

  • The Fabric Manager does not allow you to enable a partition if the required resources are not available.

  • The partition image is enabled by default when it is commissioned. You can enable the partition image if it is in disabled state.

To enable a partition image

  1. On the Fabric Manager user interface, point to System Administration, and then click CPF System.

  2. Click Platforms and Partitions.

    The Details: Platforms and Partitions screen appears.

  3. Click Partitions tab.

    The list of partition images appears.

  4. Double-click the partition image that you want to enable.

  5. On the Summary tab, click Enable.

    The Enable Partition Image window appears.

  6. In the Partition Attributes tab, enter the following details and click Next:

    • Partition Image Name: Type a name for the partition image. This should be unique across the fabric since it is required for monitoring the state and health of the partition images within FM-LAN subnet. This field is mandatory.

    • Host Computer: Type the name of the host computer. This field is mandatory.

    • Initial State on Platform Reboot: Enables you to identify whether or not the partition image is started after a platform reboot. The available values are Running and Stopped. The default value is Running.

    • Description: Type description for the partition image.

  7. In the Cores & Memory tab, edit one or more of the following fields as needed:

    • Partition Chassis: If the assigned partition chassis is not available, you can assign another available partition chassis.

      Note: The alternate partition chassis may not have the same resources as the previously assigned partition chassis.

    • Cores: Select the required number processor cores for the partition image. The number of cores available for selection depends up on the partition chassis and the number of cores available on the platform.

    • Enable Hyper-Threading: If you select this check box, two logical processors per core are selected. By default, the HT option is disabled for 4S platforms and enabled for 2S platforms.

    • Memory: Select the required memory for the partition image.

  8. Click Next.

  9. In the I/O Port Details tab, you can do the following:

    • Assign/Release/Disable the Dedicated NIC ports, logical ports of shared ports and HBA ports.

      Note: When you Assign a Disabled port, the reserved BDF is now assigned to the port.

    • If you have associated an HBA port with the partition image, then you can edit the values in the Target WWPN, and Target LUN No. fields.

  10. Click Next.

  11. In the Secure Fabric tab, you can do the following:

    • You can select new secure fabrics to associate with the partition image, or clear the previous selection of secure fabrics to disassociate them from the partition image.

    • (Optional) You can enable the FM-LAN by selecting the FM-LAN check box. Once enabled, the health of the partition changes to Ok, Warning or Unknown.

      If you have already enabled the FM-LAN, you can disable it by clearing the FM-LAN check box and the health of the partition changes to Monitoring Disabled (FM-LAN Disabled).

       Caution

      Before you enable the FM-LAN option, it is important that you understand the security risks associated with the use of the FM LAN. It is possible for an FM LAN Ethernet switch monitored by the Fabric Manager to have an access vulnerability. For more information on the security risks associated with FM LAN, see Enabling and Disabling the FM LAN.

  12. In the Storage tab, you can change the previous selections of Data LUNs. You can view the Partition SCSi No. The OS identifies the LUN by the Partition SCSi no.

  13. Click Enable.

    The status of the partition image changes to Stopped.

Notes:

  • Events for initiation and completion are logged and displayed in the event console.

  • For more information about the Configuration Details and I/O Ports tab, see Commissioning a Partition Image.
