VIOS requirement for FC and ethernet


I have some unclear about how VIOS uses its resources.

Assume that VIOS lpar has only 1 physical FC, and we use that to connect to the Lun. Then we install VIOS for the lpar on that Lun.
So my question is, afterward, we can still use that physical FC for the virtual FC we create later?

This can be same mechanism with virtual ethernet?
I have 1 physical ethernet assigned to vios, and configure IP on that, everything is fine until I tried to map another virtual ethernet to it and got the issue below:

$ mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid 2
Adapter ent0 has an interface configured over it, or it belongs to another SEA, VLAN or EtherChannel
Command did not complete.

All of these mean that we have to use another physical device (FC, ethernet) for virtual devices??

Please advise me. Very appreciated Smilie

IFDHCreateChannelByName(3SMARTCARD)			    Smartcard Library Functions 		       IFDHCreateChannelByName(3SMARTCARD)

IFDHCreateChannelByName - create a communication channel with an IFD SYNOPSIS
#include <smartcard/ifdhandler.h> RESPONSECODE IFDHCreateChannelByName(DWORD Lun, LPSTR devicename); PARAMETERS
The IFDHCreateChannelByName() function takes the following parameters: Input Lun Logical Unit Number devicename Device name path DESCRIPTION
The IFDHCreateChannelByName() function opens a communication channel with a card terminal specified by devicename. This function can use open(2) or other system call to open the device and establish a communication path. The caller of this function (smart card framework) assigns a logical unit number Lun per card terminal and slot and passes this value to IFDHCreateChannelByName(). If the IFD handler sup- ports multiple terminals with one instance of the handler (as indicated by capability TAG_IFD_SIMULTANEOUS_ACCESS), it communicates with the card terminal corresponding to this Lun. If the IFD handler supports only one terminal with one slot per instance, it can choose to ignore the Lun. The Logical Unit Number, Lun is encoded as 0xXXXXYYYY, where YYYY represents the lower 16 bits that correspond to the slot number for terminals with multiple slots. Most of the readers have only one slot, in which case YYYY is 0. XXXX represents the next 16 bits that correspond to the card terminal and can range between 0 and a number returned by TAG_IFD_SUMULTA- NEOUS_ACCESS. RETURN VALUES
The following values are returned: IFD_SUCCESS Successful completion. IFD_COMMUNICATION_ERROR An error occurred. ATTRIBUTES
