|Sun Datacenter InfiniBand Switch 36 HTML Document Collection for Firmware Version 2.0|
You can partition your InfiniBand fabric using the smpartition command and its subcommands. The smpartition command is issued from the switch that has the master Subnet Manager and acts upon the partition configuration. There are two configurations, the active configuration is the one currently in use, and the modified configuration is the one which you can affect.
You begin a configuration session with the smpartition start command. You then make changes to the modified configuration with the smpartition create, smpartition add, smpartition remove, smpartition modify, and smpartition delete commands. You finally make the modified configuration into the active configuration with the smpartition commit command.
See Switch Reference, smpartition command, for more information.
Note - There is a hardware limitation of 127 user-defined and 1 default partition for each port of the ConnectX2 chips (in HCAs) and for each InfiniBand port of the BridgeX chips (in gateways).
