Troubleshooting the OSU Upgrade

Use these cphaosu commands if there are problems during the OSU upgrade process:

• If it is necessary to roll the update back, run the cphaosu cancel command on the new upgraded Cluster Member. The old Cluster Member processes all the traffic.
• After you run the cpshaosu finish command on the old Cluster Member, you can continue to process the old traffic on the old Cluster Member and the new traffic on the new upgraded Cluster Member. Run the cphaosu restart command on the old Cluster Member.
