APAR Error Description / Circumvention

-----------------------------------------------
The IBM i cluster technology makes use of user registered
cluster node monitors to determine whether a system has truly
failed when communication is lost to the system.  When a user
registers a cluster node monitor on a node the node will
register a Common Information Model (CIM) indication handler
program in Cluster Resource Services with the CIM server
supported by a specified Hardware Management Console (HMC).
Should a node managed by the monitored HMC suffer a failure or
crash the HMC will send a message (via the CIM server) to all
registered CIM indication handlers containing data on the nature
of the failure and the node affected by the problem.  Cluster
Resource Services will take appropriate action based on the
nature of the reported failure.

The HMC is being updated to replace the existing CIM server with
a new representational state transfer (REST) based interface.
HMC version V8R8.5.0 will be the last version of HMC to support
the CIM server, and will also be the first version of HMC to
support all REST API functionality required by the IBM i cluster
monitor.

Existing cluster node monitors using the CIM server will not be
able to communicate with the HMC if the HMC version is V8R8.6.0
or later.  For later versions of the HMC the CIM cluster node
monitors must be replaced with REST cluster node monitors.

CORRECTION FOR APAR SE65416 :
-----------------------------
Cluster node monitors can be either CIM monitors or REST
monitors.  In the past only CIM cluster node monitors were
supported.
