control the order of service initialization in the Debian 9

[Marcio Demetrio Bacci <marciobacci@gmail.com>]

Hi,

I need to control the order of service initialization in my Debian 9 Server.

The problem is the following:

I beliave that my DRBD service don't start because the iscsi doesn't ready. This way, I intend to change priority of DRBD initialization  to initialize after iscsi service.

Where can I change the order of services initialization ?

Regards,
