Opened: Jul 31, 2019 Severity: 3-Major
On a VIPRION chassis provisioned as a vCMP host, mcpd on the secondary blades may restart and log errors similar to the following in /var/log/ltm: err mcpd[43273]: 01070734:3: Configuration error: DB validation exception, unique constraint violation on table (trunk_virtual_mbr) object ID (<guest_name> <PDE_interface>). A duplicate value was received for a non-primary key unique index field. DB exception text (Cannot update_indexes/checkpoint DB object, class:trunk_virtual_mbr status:13)... failed validation with error 17237812
All services on the affected secondary blades restart. vCMP guests running on those blades are disrupted until MCPD recovers
All of the following conditions must be met: - The VIPRION system is provisioned as a vCMP host with one or more deployed guests. - An abrupt loss of inter-blade connectivity occurs without a graceful secondary disconnect. - A secondary blade subsequently reconnects to the primary.
