smpartition Command

Manages the partition configuration.

Syntax

smpartition subcommand [-h]

This hardware command has subcommands that determine its functionality. This table describes the subcommands and provides their syntax.

where:

• partition_name is an alphanumeric tag to the InfiniBand partition (optional).

• p_key is the partition key (1 to 7fff or default).

  ---

  Note - You cannot delete the pre-defined partitions with P_Keys 1 and 7fff.

  ---

• mtu is the number that maps to the actual MTU (1 to 5).

  mtu Number 1 2 3 4 5 MTU Value 256 512 1024 2048 4096

• rate is the number that maps to the actual throughput of a link (link width + link speed) (2 to 10).

  rate Number 2 3 4 5 6 7 8 9 10 Rate Value in Gbps 2.5 10 30 5 20 40 60 80 120

• sl is the service level (0 to 15).

  ---

  Note - Use service level 1 (sl 1) only for low-latency, high-priority, small-message, low-bandwidth traffic. Use other service levels for regular, high-bandwidth traffic.

  ---

• scope is the multicast address scope value (1 to 14).

  ---

  Note - The mtu, rate, sl, and scope parameters are for the multicast group created when ipoib (IP over InfiniBand) is configured for the partition. Typically, these values are not specified as the defaults are sufficient for the fabric configuration.

  ---

• defmember is the default membership type (full, limited, or both) for the partition.

  ---

  Note - If ports are added to the partition without specifying the membership type, the default membership type is applied to the port

  ---

• port is the GUID of the port, or these special parameters, to add, remove, or modify:

  • ALL_CAS – All CAs in the InfiniBand fabric.

  • ALL_SWITCHES – All switches.

  • ALL_ROUTERS – All routers.

• member is the membership type (full, limited, or both) for the port.

Description

This hardware command is used to manage the InfiniBand partition and is available only on management controllers that are hosting the primary (or Master) Subnet Manager. There are two configurations for the InfiniBand partition, the active configuration and the modified configuration. When configuring a partition, you must initiate the configuration session with the smpartition start command. During the session, you create a modified copy of the active configuration. To end the session, you must use the smpartition commit 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 file.

The Subnet Manager nodes file must exist in every management controller file system. The file contains a list of 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.

Options

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

Example

This example shows how to display the active configuration of the InfiniBand partition with the smpartition command.

FabMan@switch_name->smpartition list active
# Sun DCS IB partition config file
# This file is generated, do not edit
#! version_number : 16
Default=0x7fff, ipoib : ALL_CAS=full, ALL_SWITCHES=full, SELF=full;
SUN_DCS=0x0001, ipoib : ALL_SWITCHES=full;
part1 = 0x9001,ipoib:
0x0002c90300089138=full, 
0x0002c9030008923b=full, 
0x0002c9030008923c=full, 
0x0002c90300089103=limited,
0x0002c90300089104=full, 
0x0002c90300089137=limited;
