You can configure or unconfigure an IB device on a system by using the cfgadm command. The command manages dynamic reconfiguration (DR) of the entire IB fabric as seen by a host. In addition, the command enables you to do the following:
Display the IB fabric
Manage communication services
Update P_key table databases
For more information, see the cfgadm_ib(1M) man page.
All the IB devices, such as Port, VPPA, HCA_SVC, IOC, and pseudo devices support cfgadm operations.
