In a High Availability setup (HA) running LMI 6.4.0, enabling Advance Features from the 'root' console (CLI) using command:

> system logu enable

Above command will fail due to below error:

UPDATE command query on slave to user ''@<slave_ipv6_address> for table 'OverviewModule'
Error executing query on slave node: <slave_ipv6_address>
 

The definite fix for this issue will be included in HF1 for LMI 6.4.0. In the meantime, Administrators can apply below workaround:

1) Given a public IP like 'fd00::aaaa:a73:1a87' - run on Master and Vicemaster below commands:

# mysql -e "GRANT all privileges ON *.* TO 'root'@'fd00::aaaa:a73:1a87' WITH GRANT OPTION;"

and then:

# mysql  -e "flush privileges;"

2) Now go to Master or public IP and switch to root console ( type 'su' on the 'toor' shell) - then try to enable advance features with below command:

> using system logu enable.

It enables the advanced features without any error on CLI.

3) Login to the Web UI and make sure Advanced features are available and working.
