ib-agent channel-adapter
Synopsis: The ib-agent channel-adapter command and its arguments are used to
configure the Subnet-Management Agent (SMA) node strings for channel adapters. A node string
is a descriptive string used to identify an object.
Syntax: ib-agent channel-adapter guid
The syntax is described in the following table:
Table B-48 ib-agent Command Syntax
DescriptionSyntax
Enter after the ib-agent command to configure a channel adapter.channel-adapter guid
Command Modes: Global-configuration mode.
Privilege Level: Unrestricted and InfiniBand read-write users.
Usage Guidelines: A subnet-management agent (SMA) is the intermediary between a network
manager and the network entities it manages, such as the internal InfiniBand switches and host
channel adapters. The subnet management agent maps the operations between managed
conceptual objects and the physical resources inside the system chassis, and routes event
notifications from locally managed objects to remote entities.
Each node in the fabric has a subnet management agent (SMA) to shuttle communication requests
between the node and the subnet manager. Communication between the subnet manager and
the subnet management agent is done using the common management datagram (MAD) message
structure. This structure entails the passing of subnet management packets (SMP).
The subnet management agent receives and transmits subnet management packets to and from
the subnet manager. The subnet management packets never extend beyond their respective local
InfiniBand subnet.
Internally, the InfiniBand switch is comprised of 36 switch chips. Each switch chip runs its own
subnet management agent and can be viewed by the subnet manager as a unique entity. Change
the node-string for a channel-adapter or switch to make it easier to identify.
Examples: The following example changes the node string of a channel adapter.
HP-IB(config)# ib-agent channel-adapter 00:05:ad:00:00:00:13:f7 node-string "primary HCA"
HP-IB(config)#
Defaults: This command has no defaults.
