$0 manages the VIM process as an HA resource

The 'start' ..... operation starts the vim in the active state.

The 'stop' ...... operation stops the vim.
|

The 'reload' .... operation stops and then starts the vim.
|
|
The 'status' .... operation checks the status of the vim.
|
|
The 'monitor' .... operation indicates the in-service status of the vim.
|
|
The 'validate-all' operation reports whether the parameters are valid.
|
|
The 'meta-data' .. operation reports the vim's meta-data information.
