SUMMARY OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
Patch ID: VRTSvxfen-6.0.500.100
* 3387018 (3471571) Cluster nodes may panic if you stop the HAD process by force on a node and 
reboot that node.


DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: VRTSvxfen-6.0.500.100

* 3387018 (Tracking ID: 3471571)

SYMPTOM:
Cluster nodes may panic if you stop the HAD process by force on a node and 
reboot or shutdown that node.

DESCRIPTION:
When you execute the following steps on any of the nodes in a cluster, the 
kernel may panic on any of the nodes in the cluster:

1.      Stop the HAD process with the force flag:
# hastop -local -force or
# hastop -all -force

2.      Reboot or shut down the node.

Cluster nodes may panic because forcefully stopping VCS on a node leaves all 
the applications, file systems, CVM, and other processes on that node online. 
If you reboot the node with applications and processes in online state, VCS 
triggers a fencing race  to avoid data corruption. The sub-cluster that loses 
the race panics. To ensure that rebooted node loses the race, increase LLT 
peerinact timeout on that node by running the lltconfig command.

RESOLUTION:
Symantec has fixed this issue such that rebooted node loses the 
fencing race and panics. The fix prevents the case where the rebooted node can 
win the fencing race and therefore cause other nodes in the cluster to panic.
