2665 * The following function comes from Adaptec:

2667 * Routine to be called during initialization of communications with

2669 * the adapter first boots up, it examines attached drives, etc, and
2670 * potentially comes up with a new or revised configuration (relative to
2671 * what's stored in it's NVRAM). Additionally it may discover problems
2672 * that make the current physical configuration unworkable (currently
2673 * applicable only to cluster configuration issues).
2674 *
2675 * If there are no configuration issues or the issues are considered
2676 * trival by the adapter, it will set it's configuration status to
2677 * "FSACT_CONTINUE" and execute the "commit confiuguration" action
2678 * automatically on it's own.
2679 *
2680 * However, if there are non-trivial issues, the adapter will set it's
2681 * internal configuration status to "FSACT_PAUSE" or "FASCT_ABORT"
2682 * and wait for some agent on the host to issue the "\ContainerCommand
2683 * \VM_ContainerConfig\CT_COMMIT_CONFIG" FIB command to cause the
2684 * adapter to commit the new/updated configuration and enable
2685 * un-inhibited operation. The host agent should first issue the
2686 * "\ContainerCommand\VM_ContainerConfig\CT_GET_CONFIG_STATUS" FIB
2687 * command to obtain information about config issues detected by
2688 * the adapter.
2689 *
2690 * Normally the adapter's PC BIOS will execute on the host following
2691 * adapter poweron and reset and will be responsible for querring the
2692 * adapter with CT_GET_CONFIG_STATUS and issuing the CT_COMMIT_CONFIG
2693 * command if appropriate.
2694 *
2695 * However, with the introduction of IOP reset support, the adapter may
2696 * boot up without the benefit of the adapter's PC BIOS host agent.
2697 * This routine is intended to take care of these issues in situations
2698 * where BIOS doesn't execute following adapter poweron or reset. The
2699 * CT_COMMIT_CONFIG command is a no-op if it's already been issued, so
2700 * there is no harm in doing this when it's already been done.
