Users Affected
--------------
Customers may be exposed to this problem if they have the bos.clvm.enh
fileset at a level of 5.3.0.62 through 5.3.0.64.  They must also be
using Concurrent LVM, which is utilized by HACMP Resource Groups using
Fast Disk Takeover or the 'Online on All Available Nodes' Startup Policy.


Problem Description
-------------------
On extremely busy clusters, or clusters experiencing poor network
communication, the concurrent LVM daemon (gsclvmd) on a node may fail
to respond to a responsiveness check issued by Group Services. In this
case, we will force the Volume Group offline on that node to ensure there
is no possibility that future LVM configuration changes will cause the
Volume Group definition to become out of sync between the two nodes.
However, forcing the VG offline could lead to unexpected downtime of
applications using that volume group, or potential problems during HACMP
failover.


Installation
------------
The fix needs to be installed on both nodes and then the cluster restarted
on each node to be effective.

- Download clvm_6_2.epkg.Z in binary format.

- Install the fix using the command:

  emgr -e clvm_6_2.epkg.Z

Replace this interim fix with APAR IZ13557 when available.
