## This test proves that group replication does not start on server when it's
## lower_case_table_names does not match with the group.
##
## Test:
## 0. This test requires 2 members.
## 1. Verify lower_case_table_names cannot be set while server is
## running and start GR on server-1.
## 2. Store variables of server-2 for restart.
## 3. Test GR does not start on server when lower_case_table_names
## does not match.
## 3A. Test GR does not start on boot when lower_case_table_names
## does not match.
## 3B. Test GR does not start with command when lower_case_table_names
## does not match.
## 4. Cleanup.
