The user preference for a persistent 'FCID' for
this Virtual Device.
The value of the corresponding instance of
cFcSdvVdVirtDomain specifies the Domain identifier
part of the FCID. When the values for both
cFcSdvVdVirtDomain and cFcSdvVdFcId are specified
during row creation, the Domain ID part of
cFcSdvVdFcId value should exactly match the value
of cFcSdvVdVirtDomain.
If the value of this object is not explicitly set
by the user, the system generates and uses a
FCID for this Virtual Device. The value of
'000000'h indicates no user preference.
