All services on one or all secondary blades in a VIPRION chassis restart, and MCPD logs errors similar to the following: -- err mcpd[9063]: 01070734:3: Configuration error: DB validation exception, unique constraint violation on table (sflow_vlan_data_source) object ID (1168). A duplicate value was received for a non-primary key unique index field. DB exception text (Cannot update_indexes/checkpoint DB object, class:sflow_vlan_data_source status:13) -- err mcpd[9063]: 01070734:3: Configuration error: Configuration from primary failed validation: 01070734:3:Configuration error: DB validation exception, unique constraint violation on table (sflow_vlan_data_source) object ID (1168). A duplicate value was received for a non-primary key unique index field. DB exception text (Cannot update_indexes/checkpoint DB object, class:sflow_vlan_data_source status:13)... failed validation with error 17237812. In versions prior to v11.6.0, the error is: 'Can't save/checkpoint DB object,' rather than 'Can't update_indexes/checkpoint DB object'.
MCPD restart on all secondary blades results in partial service outage.
Multi-bladed VIPRION system, where the 'if-index' value for VLANs differs between blades. You can check the 'if-index' value by running the following command on each blade: tmsh list net vlan all if-index.
Reactivate the license only on a system that is standby/offline.
Reactivating the license on a VIPRION system no longer causes MCPD process restart on one or all secondary blades.
