Configuring and Installing I/O Domains
12c Release 2 (220.127.116.11.0)
This guide provides an end-to-end example for how to use Oracle Enterprise Manager Ops Center.
Using Oracle Enterprise Manager Ops Center, you can configure and install I/O domains on Oracle VM Server for SPARC systems.
A logical domain is a virtual machine with resources, such as CPU threads, memory, I/O devices, and its own operating system. An I/O domain is a logical domain that has PCIe Endpoint devices assigned to it in Oracle Enterprise Manager Ops Center. Therefore, the I/O domain is defined as Physical I/O Domain in the UI. The PCIe Endpoint devices are manually released from the PCIe bus using the CLI.
The released PCIe Endpoint devices are then available for creating I/O domains. The PCIe bus must be allocated to primary or root domain before releasing the PCIe Endpoint devices.
The number of I/O domains that you can create depends on the number of PCIe Endpoints that are available in a PCIe bus.
In this how to, the following scenario is set to create an I/O domain:
Oracle VM Server for SPARC 3.1 version installed on Oracle SPARC T4-2 server.
A PCIe bus pci_1 is detached from the primary domain while provisioning Oracle VM Server for SPARC.
A root domain is created with the detached PCIe bus. The OS is provisioned on the root domain.
The PCIe Endpoint devices are released from the PCIe bus pci_1.
Use the released PCIe Endpoint and create the I/O domain. Then, provision OS on the domain.
You need the following to configure and deploy an I/O domain:
Oracle VM Server for SPARC system
A server installed and configured with Oracle VM Server for SPARC 3.1 version using Oracle Enterprise Manager Ops Center. Refer to the guide Oracle Enterprise Manager Ops Center Configuring and Deploying Oracle VM Server for SPARC.
Root domain installed and provisioned with OS. Refer to Configuring and Installing Root Domains for detailed procedure.
Obtain the details of the Ethernet devices connected to the PCIe bus that will be assigned to the root domain. You must acquire the network interfaces in the PCIe Endpoint device that are physically connected to the network.
The network to which the network interface is physically connected must be discovered and managed in Oracle Enterprise Manager Ops Center.
An IP address to be assigned to the I/O domain OS.
The local library is used for virtual disks of the I/O domain. The I/O domain is not migratable and hence the I/O domain metadata is stored in the local library automatically. In this example, 20 GB of virtual disk is created for the I/O domain.
You must install and configure Oracle Enterprise Manager Ops Center in Oracle Solaris 11 OS and populate the Oracle Solaris 11 Library with SRUs. You can select an Oracle Solaris 11 OS of particular SRU version.
Refer to Oracle Enterprise Manager Ops Center Feature Reference Guide for more information about uploading or importing OS images.
Roles and Permissions
A user with the following roles:
Virtualization admin role to create I/O domains and server provisioning.
Plan/Profile admin role to create profiles and plan for I/O domain creation and OS provisioning.
In this example, the I/O domain is installed on Oracle VM Server for SPARC 3.1 version. The control domain is configured and deployed in stand-alone mode and it is not placed in a server pool. The PCIe Endpoint for the I/O domain is from the PCIe bus allocated to the root domain. In the Oracle VM Server for SPARC system, the root domain is first created and provisioned with OS. The root domain is displayed in the UI as follows:
From the root domain, a PCIe Endpoint device is released manually and assigned to the I/O domain. Refer to Oracle VM Server for SPARC documentation at
http://www.oracle.com/technetwork/documentation/vm-sparc-194287.html">>http://www.oracle.com/technetwork/documentation/vm-sparc-194287.html for more information about the commands for releasing the PCIe Endpoint devices.
The steps to configure and install I/O domain are as follows:
Create an I/O domain with the following resource requirements:
Two CPU Threads
4 GB of memory. You must provide 4 GB of memory for each I/O device.
Native CPU architecture
Local filesystem library for the virtual disks
In this example, virtual network connection is not provided for the I/O domain. Instead, an Ethernet connection to one of the PCIe Endpoint device assigned to the I/O domain will be used for providing the physical network connection for OS provisioning.
You can provide virtual network connection to I/O domain when the I/O domain does not have Ethernet device and has only storage device such as Fibre Channel cards.
In Oracle Enterprise Manager Ops Center, you create I/O domains that have physical resources assigned to them and hence the option Physical I/O Domain in the Subtype of Create Logical Domain profile creation.
Select the Plan Management section.
Expand Profiles and Policies and select Logical Domain.
Click Create Profile from the Actions pane.
The Create Logical Domain Profile wizard is displayed.
Enter a name and description to identify the profile.
Retain the option to create a deployment plan for this profile. Select Physical IO Domain in the Subtype.
Enter the name of the I/O domain as io_domain and the starting number as 1. The I/O domain will be created with the name as io_domain1.
Provide description and add new tags for the I/O domain. All the logical domains created using this profile use the same description and tags.
Click Next to configure the CPU Threads and memory.
The threads in the physical CPU of the Oracle VM Server are dedicated to the logical domains. Select Virtual CPU as the CPU Model and enter the values for CPU Threads and memory to be allocated for the I/O domain:
2 CPU Threads.
4 GB of memory.
Do not specify a value for Crypto Units. Depending on the number of CPU threads, the Crypto units are assigned automatically.
Specify the PCIe Endpoint Type and number of devices that must be allocated to the I/O domain. The type can be Ethernet, InfiniBand, SCSI, Fibre Channel or Any type.
In this example, an Ethernet device is selected and one PCIe Endpoint device is allocated to the I/O domain.
Click Next to specify the storage for the logical domains.
Select the local file system storage library for the virtual disks. Enter the disk size as 20 GB. You can retain or edit the name of the virtual disk.
Click Next to specify the networks for the domains.
Skip this step to specify the networks that must be used for OS provisioning. The physical connection network is used from the Ethernet device in the PCIe Endpoints assigned to the I/O domain.
Click Next to view the summary of the logical domain details.
Review the information and click Finish to save the profile.
The profile to create to the I/O domain and the corresponding deployment plan are created. Apply the deployment plan to create the I/O domain.
Deploy the automatically created I/O domain plan to create I/O domain. The I/O domain is created without any OS provisioned on it.
Select the Plan Management section in the Navigation pane.
Expand Deployment Plan and select Create Logical Domains.
Select the plan from the list of plans and click Apply Deployment Plan in the Actions pane.
In the Select Targets window, select the Oracle VM Server for SPARC system on which you want to create the I/O domain.

The Specify Domain Identity step is displayed. Confirm the given name in the profile.
Click Next to proceed.
Specify the PCIe Endpoint devices for the I/O domain. The PCIe Endpoints that are released from the root domain are listed in the Alias.
In the Storage Resource Assignments step, retain the storage library selected for the virtual disks from the profile.
There is only one path to access the backend storage and the multipathing group name is not entered. Therefore, multipathing group is not created for this virtual disk.
The virtual disk server is named as io_domain1-vds0 by default. If required, you can modify the name of the virtual disk server.
In the profile to create I/O domain, the network connections details were not provided. Therefore, the network connection settings step and network resource step are empty.
Schedule the job to run now.
Review the properties and click Apply to apply the deployment plan to create logical domain.
The I/O domain is created and is in installing state. The domain is displayed under the corresponding Oracle VM Server for SPARC system. Now, apply OS provisioning deployment plan to provision OS on the domain. The PCIe Endpoint device is assigned to the I/O domain. The PCIe slot status will be updated once the OS is provisioned on it.
Create a new OS provisioning profile for the Oracle Solaris 11.1 OS that must be provisioned on the I/O domain. You can also edit the default profiles that are created for the Oracle Solaris 11.1 OS. The procedure in this section describes about creating a new OS provisioning profile.
Select the Plan Management section in the Navigation pane.

Select the OS Provisioning Profile and the OS Configuration Profile created for provisioning OS on the I/O domain.
Click Save to save the deployment plan.
For provisioning OS on the I/O domain, two important parameters are required:
Boot interface details: The details can be either the network port number of the PCIe Endpoint device, or the MAC address of the interface.
OS Provisioning IP Address: The IP address that must be used on the OS. If you have more than one interfaces defined to be used on the OS, the network slot and the IP address for each network connection.
In this scenario, the I/O domain creation and OS provisioning plan are not combined in a single plan. Hence, the available PCIe Endpoint devices are filtered and provided in the boot interface list.
Select the I/O domain in the Assets tree of the Navigation pane.
Click Install Server in the Actions pane.
The Install Server window is displayed.
Select the OS provisioning plan created for deploying the OS and apply the plan in minimal interaction mode.

Click Next in the Introduction step.
The plan consists of the OS provisioning profile and OS configuration profile. The application of the plan starts with the Provision OS step.
Click Next to define the boot interface resources.
In the Boot Interface Resource Assignment step, enter the following details:
Select the network from the list. The networks that are discovered and managed in Oracle Enterprise Manager Ops Center are listed.
Select the PCIe Endpoint device that provides the network interface for the network connection.
In this example, select
PCIE9(pci_1) as the Controller. The Controller displays only those devices that are available for network connection. It does not display all the devices.
Select the interface from the list of interfaces available for that PCIe slot. In this example, the net_3 is the network interface that is physically connected to the selected network.
Provide the IP address for the boot interface.
(Optional) Provide the host name for the target.
Review the summary of information for OS provisioning and click Next.
The application of the OS configuration profile starts in the wizard. Click Next.
The boot interface network details are populated in this step. In this example, there was only one network interface selected to be configured on the OS. Therefore, the network resource is populated with the boot interface network details.
If you have selected more than one interface to be configured on the OS, the first interface is always overwritten by the boot interface network details. Always define the first interface as the boot interface. You can select the interface that you want to be the primary interface. Specify the network resources for the selected interfaces:
If you have selected more than one interface to be configured on the OS, then specify the network resources for the interfaces:
Select the network in the Network column.
Select the PCIe Endpoint device in the Controller column. The PCIe Endpoint device provides the network interface for communication.
Select the network interface.
Enter the IP address for OS provisioning.
Select the primary interface.
In this example, the OS is not placed in a server pool for zones.
Review the summary of OS configuration parameters and click Next.
Schedule the job to run now and click Apply.
The provisioning job is executed and the I/O domain is provisioned with the OS and displayed in the UI:
You can view the I/O Resources tab of the I/O domain that displays the details of the PCIe Endpoint device allocated to the domain:
From the control domain, smt4v2-3, you can also view that the PCIe Endpoint device allocated to the I/O domain is from the PCIe bus assigned to the root domain.
You can provide virtual I/O resource services to other guest domains in the control domain. You can also create zones on these domain and provide the resources to the zones.
