After head less , if SC is starting ,
I can see some code in IMMD Waiting 3 seconds to allow IMMND MDS attachments to
get processed.
============================================================================
if (cb->mScAbsenceAllowed && cb->ha_state == SA_AMF_HA_ACTIVE) {
/* If this IMMD has active role, wait for veteran payloads.
* Give up after 3 seconds if there's no veteran payloads. */
LOG_NO("Waiting 3 seconds to allow IMMND MDS attachments to get
processed.");
if (osaf_poll_one_fd(m_GET_FD_FROM_SEL_OBJ(immd_cb->veteran_sync_sel),
3000) != 1) {
TRACE("osaf_poll_one_fd on veteran_sync_sel failed or timed
out");
} else {
LOG_NO("Received intro message from veteran payload, stop
waiting");
}
m_NCS_LOCK(&immd_cb->veteran_sync_lock, NCS_LOCK_WRITE);
m_NCS_SEL_OBJ_DESTROY(&immd_cb->veteran_sync_sel);
m_NCS_UNLOCK(&immd_cb->veteran_sync_lock, NCS_LOCK_WRITE);
}
/===========================================================================
Ideally this should be timer insted of poll like AMFD node_sync_tmr
============================================================================
if (rc_node_up == sync_nd_size) {
if (cb->node_sync_tmr.is_active) {
avd_stop_tmr(cb, &cb->node_sync_tmr);
TRACE("stop NodeSync timer");
}
cb->all_nodes_synced = true;
LOG_NO("Received node_up_msg from all nodes");
} else {
if (avnd->node_up_msg_count == 1 &&
(act_nd ||
n2d_msg->msg_info.n2d_node_up.leds_set)) {
// start (or restart) timer if this is the
first message
// from amfnd-active-SC or amfnd-green-leds-PL

** [tickets:#1955] imm: Fail to detect veteran node when NCSMDS_UP event comes
late**

Sometimes, the NCSMDS_UP event comes after the messages.
In this case, IMMD received the IMMD_EVT_ND2D_INTRO message before the
NCSMDS_UP event.
IMMD failed to process the intro message because the node info had not been
added to cb->immnd_tree.

~~~
IMMND on SC-1 was elected as coordinator insted of the veteran.
The MDS messages come from 'Dsock' socket and MDS events come from 'BSRsock'.
Since MDS uses two different sockets so I think we can't fix this problem in
MDS.
IMM has to somehow handle this case.
