** [tickets:#2391] IMM: OI should not receive callbacks on a locked node**

**Status:** fixed
**Milestone:** 5.2.RC2
**Created:** Wed Mar 22, 2017 09:08 AM UTC by Chani Srivastava
**Last Updated:** Mon Mar 27, 2017 05:46 AM UTC
**Owner:** Neelakanta Reddy


**Environment details**

OS : Suse 64bit
Changeset : 8701 ( 5.2RC1)
Setup : 4 nodes

**Steps to Reproduce:**
* Create a test class
* Node1 - Initialize OM with A.2.18
* Node2 - Initialize OI with A.2.18
* Node2 - Make OI implementer for the test class created
* Node2 - Call OiDispatch
* Lock Node2
* Node1 - Try creating an object for test class for which OI is an implementer

OI receives CreateCallback and responds with SA_AIS_OK

**Expected**: On a clm locked node, OI should not receive any callback when 
initialize with A.2.18

[tickets] [opensaf:tickets] #2391 IMM: OI should not receive callbacks on a locked node

[Neelakanta Reddy]

- **Part**: doc --> nd
- **Comment**:

>From The README:

IMMD is not yet integrated, as the IMMND has to services to clients with lesser 
versions.
IMMND has to be UP even if the CLM node is down. The IMMD integration has to be 
done along
with Enhanced cluster management(#439).

since IMMND is up, on the CLM locked node, OI is receiving callback and 
responds.

>From the IMM spec:
When the cluster node leaves the membership, the IMM Service executing on the
remaining nodes of the cluster behaves as if all processes that were using the 
IMM
Service on the leaving cluster node had been terminated. **In particular, if a 
process on
the leaving cluster node was registered as an Object Implementer, the IMM 
Service
will unregister it automatically**

Following is the observation:

1. since, to service clients with lesser version, IMMND is not down on the node 
the same has been updated in README.
2. when calling object implementer registered with A.02.18, the callback is 
allowed as there is no proper return code and implementers are not unregistered.

solution:
when the node is locked, and there are OI registered with A.02.18 with 
implementers, then these implementers will be unregistered.
