Server pool {0} is internally managed as part of administrator-managed database configuration and therefore cannot be removed directly via srvpool object.
Cause
An attempt was made to remove configuration of an internally managed server pool that is hosting an administrator-managed configuration.
Action
Do not remove this server pool via srvpool object directly. Instead use the command 'srvctl remove service/database' to remove this server pool and any service/database hosted by the server pool.
