--- Start phase 1 - Qmgr -------------------------------------------

1) Set timer 1 - TimeToWaitAlive

2) Send CM_REGREQ to all connected(and connecting) nodes

3) Wait until -
a) The precident answers CM_REGCONF
b) All nodes has answered and I'm the candidate -> election won
c) 30s has passed and I'm the candidate -> election won
d) TimeToWaitAlive has passed -> Failure to start

When receiving CM_REGCONF
4) Send CM_NODEINFOREQ to all connected(and connecting) nodes 
   reported in CM_REGCONF

5) Wait until -
a) All CM_NODEINFO_CONF has arrived
b) TimeToWaitAlive has passed -> Failure to start

6) Send CM_ACKADD to president

7) Wait until - 
a) Receive CM_ADD(CommitNew) from president -> I'm in the qmgr cluster
b) TimeToWaitAlive has passed -> Failure to start

NOTE:
30s is hardcoded in 3c.
TimeToWaitAlive should be atleast X sec greater than 30s. i.e. 30+X sec
to support "partial starts"

NOTE:
In 3b, a more correct number (instead of all) would be
N-NG+1 where N is #nodes and NG is #node groups = (N/R where R is # replicas)
But Qmgr has no notion about node groups or replicas

--- Start phase X - Qmgr -------------------------------------------

President - When accepting a CM_REGREQ
1) Send CM_REGCONF to starting node
2) Send CM_ADD(Prepare) to all started nodes + starting node
3) Send CM_ADD(AddCommit) to all started nodes
4) Send CM_ADD(CommitNew) to starting node

Cluster participant -
1) Wait for both CM_NODEINFOREQ from starting and CM_ADD(Prepare) from pres.
2) Send CM_ACKADD(Prepare)
3) Wait for CM_ADD(AddCommit) from president
4) Send CM_ACKADD(AddCommit) 
 
--- Start phase 2 - NdbCntr ----------------------------------------

- Use same TimeToWaitAliveTimer

1) Check sysfile (DIH_RESTART_REQ)
2) Read nodes (from Qmgr) P = qmgr president

3) Send CNTR_MASTER_REQ to cntr(P)
   including info in DIH_RESTART_REF/CONF

4) Wait until -
b) Receiving CNTR_START_CONF -> continue
b) Receiving CNTR_START_REF -> P = node specified in REF, goto 3
c) TimeToWaitAlive has passed -> Failure to start

4) Run ndb-startphase 1

--
Initial start/System restart NdbCntr (on qmgr president node)

1) Wait until -
a) Receiving CNTR_START_REQ with GCI > than own GCI
   send CNTR_START_REF to all waiting nodes
b) Receiving all CNTR_START_REQ (for all defined nodes)
c) TimeToWait has passed and partition win
d) TimeToWait has passed and partitioning 
   and configuration "start with partition" = true

2) Send CNTR_START_CONF to all nodes "with filesystem"

3) Wait until -
   Receiving CNTR_START_REP for all starting nodes

4) Start waiting nodes (if any)

NOTE:
1c) Partition win = 1 node in each node group and 1 full node group
1d) Pattitioning = at least 1 node in each node group
-- 
Running NdbCntr

When receiving CNTR_MASTER_REQ
1) If I'm not master send CNTR_MASTER_REF (including master node id)
2) If I'm master
   Coordinate parallell node restarts
   send CNTR_MASTER_CONF (node restart)
