createfabric Command - Sun Datacenter InfiniBand Switch 36 HTML Document Collection for Firmware Version 2.1

Subcommand Syntax	Description
`start from-current\|empty`	Initiates a configuration based upon a currently used configuration or an entirely new one.
`add-element\|force-add-element -name hostname -ilomIp IP_address [-redundantIP IP_address`]	Adds a fabric element to the edited configuration. The `force` prefix adds the element without validation. Use this prefix when you are configuring an element without verification of bindings.
`modify-element\|force-modify-element -name hostname [-ilomIp IP_address][-redundantIP IP_address]`	The `force` prefix modifies the element without validation. Use this prefix when you are modifying an element without verification of bindings.
`delete-element -name hostname`	Removes a fabric element from the edited configuration.
`complete`	Completes the configuration process and commits the edited configuration to become the active configuration.
`list active\|modified`	Displays the active or modified configuration.
`abort`	Abruptly ends the configuration session. All edited configuration information is lost, and the active configuration remains unchanged.

where:

hostname is the host name of the element.
IP_address is the IP address for the element recognized by Oracle ILOM or IPoIB.

Description

This hardware command correlates the fully qualified domain names, the Oracle ILOM IP address, and redundant IP address of the fabric elements in the InfiniBand fabric into a fabric configuration file. Fabric elements are typically management controllers hosting Subnet Manager instances.

There are two configuration files, the active configuration and the modified configuration. When creating a configuration file, you must initiate the configuration session with the createfabric start command. During the session, you can create a modified copy of the active configuration or an entirely new configuration. To end the session, you must use the createfabric complete command to make the modified configuration the active configuration. Once committed, the active configuration is distributed to all Subnet Managers in the InfiniBand fabric where the management controller's IP addresses are listed in the Subnet Manager nodes (smnodes) list.

Like the smnodes list, the fabric configuration file must exist in every management controller filesystem. The file contains a list of Oracle ILOM IP addresses and redundant IP addresses of all active management controllers hosting a Subnet Manager in your fabric. The file should have an entry for every Sun Datacenter InfiniBand Switch 36 and Sun Network QDR InfiniBand Gateway Switch that runs a Subnet Manager in your InfiniBand fabric.

Note - If the Subnet Manager nodes of your InfiniBand fabric ever change (disabled, added, and so on), you must update all copies of the fabric configuration file.

This table describes each of the columns of the output of the createfabric list active and createfabric list modified commands.

Column Heading	Description
`Hostname`	Name of the element. The host name of the management controller hosting a Subnet Manager.
`ILOM IP Addr`	IP address of the element, recognized by Oracle ILOM.
`Redundant IP Addr`	IP address of the element, used by IPoIB.

The createfabric command is available from the /SYS/Fabric_Mgmt Linux shell target of the Oracle ILOM CLI interface.

Options

This table describes the options to the createfabric command and their purposes.

Option	Purpose
`-name`	Specifies the element host name.
`-ilomIp`	Specifies the IP address of the element recognized by Oracle ILOM.
`-redundantIp`	Specifies a second IP address of the element:
`-h`	Provides help.

Example

This example shows how to display the current fabric configuration file with the createfabric command.

FabMan@switch_name->createfabric list active
Hostname                                 ILOM IP Addr            Redundant IP Addr 
--------------------------------         --------------------    ----------------
mnm12-36p-1                              123.45.67.89            -
