Oracle I/O Domain Administration Guide

Create an I/O Domain With an OVM Template (Deprecated)

This feature is no longer available as of SuperCluster version 3.0 (or later). The following procedure applies to SuperCluster version 2.6 or earlier.

You can use a recipe to assign the amount of resources to the domain, or you can define the resources on the fly. If you plan to use a recipe, it must exist before you perform this procedure. See Choose an I/O Domain Creation Method.

The domain is not installed and available until you deploy it. When you deploy the domain, the OS and the application associated with the template are installed and configured. See Deploy an I/O Domain.

The assistant does not allow you to assign more resources than are available.

1. Access the SuperCluster Virtual Assistant.

   See Log In to the SuperCluster Virtual Assistant.

2. In the navigation panel, select I/O Domains.
3. Click Add.
   
4. Define these parameters to create a domain with an OVM template.

   • Domain Type – Choose an OVM template. If templates are available, they are listed under the OVM Template Domains separator.

   • Resource Recipe – Choose one of these options:

     • A Small, Medium, Large, or any other recipe – See Managing Recipes and Templates.

     • Custom – Enter resource allocations for cores, memory, and 10GbE interfaces. See Step 5.

       Note – If you want to assign a 10GbE NIC port pair to the I/O Domain, you must use this method. For information about port pairs, see Configure Port-Paired Networks (Administrators).

   • Network Recipe – Choose one of these options:

     • One of the network recipes – See Create a Network Recipe.

     • Custom Recipe – Enter the network parameters.

5. If you selected Custom Resource Recipe, define these resources and click Next.

   • Number of Cores – Choose a minimum of one core for domain.

   • Memory – Choose a minimum of 16 GB Memory for this domain.

   • Number of 10GbE Interfaces – Choose up to two 10GbE interfaces for this Domain.

   • Number of FC ports – Choose up to two assignable fibre channel ports for this domain.

6. If you selected Custom Network Recipe for the network, define these resources and click Next.

   • Domain Name – Type domain name, such as example.com, for this domain.

   • Name Servers – Type a list of comma or space-separated IP addresses of name servers for this domain.

   • Time Servers – Type a list of comma or space-separated IP addresses of time servers for this domain.

   • Time Zone – Choose a time zone for this domain.

7. Review the resources and click Next.

   ---

   Note -  If you requested more resources than are available, the assistant highlights the resources that are not available.

   ---

   
   
8. Choose a physical host and add network information.
   

   Configure these parameters:

   • Physical Host – Choose the compute node where this domain will reside.

   • Management Network – You can select the Management Network from which to assign an IP Address. All Management Networks defined in the Added Network Resources table of the Network Resources page with sufficient free IP Addresses can be selected. If the Resource Recipe for the I/O Domain that you are configuring contains two Management Interfaces, you will see two sets of inputs in order to provide two entries for the Management Network, IP Address, VLAN Tag, and Hostname. In this case, two Management interfaces will be configured in the I/O Domain after it has been deployed. If the I/O Domain has two Management Interfaces, then each of those Management Interfaces can use any Management Network with sufficient available IP Addresses.

   • Management Hostname – Type a unique name for this domain.

   • Network Endpoint – This option is only displayed when port pairs are configured (see Configure Port-Paired Networks (Administrators)).

     If port pairs are configured, select the network endpoint that you want the I/O Domain to use.

     
     

   • Client (10Gb) Network – You can select the Client Network from which to assign an IP Address. All Client Networks defined in the Added Network Resources table of the Network Resources page with sufficient free IP Addresses can be selected. If the Resource Recipe for the I/O Domain that you are configuring contains two Client (10Gb) Interfaces, you will see two sets of inputs in order to provide two entries for the Client Network, IP Address, VLAN Tag, and Hostname. In this case, two Client (10Gb) interfaces will be configured in the I/O Domain after it has been deployed. If an I/O Domain has two Client Interfaces, then each of those Client Interfaces can use any Client Network with sufficient available IP Addresses.

     

   • Client (10Gb) Hostname – Use the default, or type a unique name for the client network for this domain.

   • Client (10Gb) IP Address – Displayed only if the IP Address assignment is set to manual. See Configure How IP Addresses are Assigned (Administrators). When this setting is enabled, you see a drop-down list of IP Addresses from the selected Client (10Gb) Network and you can select the desired IP Address.

   • Client (10Gb) VLAN Tag – This field is always present on the I/O Domain configuration page, even if you did not define any VLAN tags in the Network Resources section. The default is no VLAN tag, which is indicated by ---.

   • Storage IB Network – Depending how the assistant is configured, the IP address might be automatically assigned or you might be able to choose an available IP address for the ZFS Storage Network. See Configure How IP Addresses are Assigned (Administrators).

   • OVM Template Properties – Parameters that might be displayed here are based on information specified in the OVM template. For more information, see Upload an OVM Template (Deprecated).

9. Click Allocate to create the domain using an OVN template.

   The SuperCluster Virtual Assistant reserves the system resources but does not deploy the configuration. You can deploy the domain at your convenience. See Deploy an I/O Domain.

   This process takes time. Watch the status in the I/O Domain screen and check the queue for progress.

   If the assistant detects a resource configuration issue, the assistant displays a message:

   • Insufficient resources. For example:

     Insufficient Unallocated Cores available on the chosen Compute Node. 10 Requested, 
     8 Remaining
     

   • Configurations that might have performance issues. For example:

     Error: VF allocation requires dedicated core in the same locality group for
     performance reasons.
     requested core count: 1  optimal core count based on number of requested VFs: 2
     

   If you receive one of these messages, click Cancel and configure a new domain using a recipe that requests fewer or different resources.

10. Verify that the domain allocation completed.

    A confirmation panel is displayed at the top of the I/O Domains screen. The State column displays the status of the allocation.

    ---

    Note -  Domains that are created from an OVM template might take extra time to reach the Resources Allocated state because additional application installation and configuration activities are performed.

    ---

    
    
11. Add the management and client networks to DNS.

    The network host names and IP addresses are displayed in the confirmation panel in the I/O Domains screen, and available when you view the domain's details.

12. Consider your next action.

    • Deploy the domain – See Deploy an I/O Domain.

    • Go to the Domain Configuration Task Overview – See Domain Configuration Task Overview.

    • Monitor activity – See Monitoring Activity, Resource Alterations, and Health.
