Rolling Software Upgrades
Steps for Rolling Upgrades
Appendix E 393
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.
See “Editing Security Files” on page 182 for more information about the
new access policies.
