Serviceguard for Linux Version A.11.16 Release Notes
Compatibility Information and Installation Requirements
Chapter 136
NOTE Be sure to plan sufficient system capacity to allow moving the
packages from node to node during the process without an
unacceptable loss of performance.
If a cluster were to fail before the rolling upgrade was complete (perhaps
due to a catastrophic power failure), the cluster can be restarted by
entering the cmruncl command from a node which has been upgraded to
the latest revision of the software.
Keeping Kernels Consistent
If you change kernel parameters as a part of doing a rolling upgrade, be
sure to change the parameters similarly on all nodes that can run the
same packages in a failover scenario.
Migrating cmclnodelist entries to A.11.16 The cmclnodelist file is
deleted when you upgrade to Serviceguard Version A.11.16.
The information in it is migrated to the new Access Control Policy form.
All the
hostnode username pairs from the cmclnodelist file are now
triplets in the cluster configuration file, and all have the role of Monitor.
If you want to grant administration roles to non-root users, add more
entries in the configuration file.
The cmclnodelist will remain until all nodes in the cluster are at
Version A.11.16.
