Product and Software: This article applies to all MMS servers and appliances and ArubaOS 2.1.x and later.
After you are logged in to the MMS server via ssh as root, run the following command:
/opt/aruba/solid/solsql -e "admin command 'hsb state'" dba dba
The expected states are:
Active MMS: PRIMARY ACTIVE
Standby MMS: SECONDARY ACTIVE
Any other state means there is a problem with the HA redundancy.
