Manages the partition configuration.
smpartition sub-command [-h]
This hardware command has sub-commands that determine its functionality. This table describes the sub-commands and provides their syntax.
partition_name is the identifier of the InfiniBand partition.
p_key is the partition key (1 – 7fff or default).
mtu is the value of the MTU.
rate is the throughput of a link (link width + link speed) in Gbps from 2.5, 5, 10, 20, 30 to a maximum of 40.
sl is the service level.
scope is the multicast address scope value (0 – F).
Note - The mtu, rate, sl, and scope parameters are for the multicast group created when ipoib (IP over InfiniBand) is configured for the partition.
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 the special parameter, to add, remove, or modify:
ALL – All of the CAs, switches, and routers in the InfiniBand fabric.
ALL_CAS – All CAs in the InfiniBand fabric.
ALL_SWITCHES – All switches.
ALL_ROUTERS – All routers.
SELF – The Master Subnet Manager.
member is the membership type (full, limited, or both) for the port.
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.
Note - If the Subnet Manager nodes of your InfiniBand fabric ever change (disabled, added, and so on), you must update all copies of the Subnet Manager nodes file.
This table describes the options to the smpartition command and their purposes.
This example shows how to display the active configuration of the InfiniBand partition with the smpartition command.
