Hans, 

The purpose is to stall (MDS based) communication, with a node that has
exited cluster, as soon as possible.

-----------
Example:
Assume a system with nodes named A,B,C and D.  If the node D were to
exit the system, then "AVNDs" on A,B and C would get a message saying
"node D has left the cluster". This would cause invocation of
"tipc_reset.h" in A,B and C nodes to disconnect them from D. The
expected result is that the TIPC links towards D (viz A<->D, B<->D,
C<->D) get immediately disabled. 
-----------

This feature is useful if the TIPC link tolerance (== link health-check
timeout) is set to value higher than the default 1.5s. A higher TIPC
link tolerance avoids unnecessary TIPC connection failures in scenarios
where a temporary link failure (and its resolution) takes greater than
1.5s. Due to lack of a better link reset/disable support in TIPC,
"tipc_reset.sh" uses a workaround of temporarily bringing down the link
tolerance to a low value.

Hope this helps.

Regards, 
Phani

PS: AVND = Availability Node Director (part of SCAP/PCAP executables)

Subject: [Users] Purpose of tipc_reset.sh?

I currently don't have tipc_reset.sh working since tipc-config 
is not in 
/opt/TIPC (and it will never be). But what is the purpose of this 
script? I can see it is used by avnd when a node has left the cluster.

Regards,
Hans
