If the p_key table information of an HCA ports changes, for example, additional p_keys are enabled or disabled, InfiniBand Transport Framework (IBTF) and IBDM need to be notified so that their internal p_key databases are updated. The cfgadm command helps update the p_key databases of IBTF and IBDM. For more information, see ibtl(7D) and ibdm(7D).
