If the iscsid_request call in iscsid_req_by_rec_async failed we would
return the err value here. Then in iscsiadm.c we do:
{
......
rc = iscsid_req_by_rec(MGMT_IPC_SESSION_LOGIN, rec);
In the line above we set rc to the err value returned when
iscsid_req_by_rec called iscsid_req_by_rec_async and failed.
/* we raced with another app or instance of iscsiadm */
if (rc == MGMT_IPC_ERR_EXISTS) {
if (async_req)
free(async_req);
return 0;
} else if (rc) {
And then right here we see rc is a error.
iscsid_handle_error(rc);
Finally here we print out the initiator reported error XYZ here.
if (async_req)
free(async_req);
return ENOTCONN;
}
} else if (rc) {
iscsid_handle_error(rc);
if (async_req)
free(async_req);
return ENOTCONN;
.....
}
If the iscsid_req_by_rec call to iscsid_req_by_rec_async is successful
then we will return the error value of that below. And then again we
would set rc to that return value and evaluate like it above in the
iscsiadm.c snippet.

For your #2 issue you are right that is messed up.
