Configuring EMS Communication
To automate the process of mounting and dismounting virtual tapes on a NonStop host server, you
must configure the Event Management System (EMS) on VTS. The EMS service for host servers
starts the EMS distributor on the host server by issuing a Tandem Advanced Command Language
(TACL) command. The distributor notifies the VTS EMS service when an EMS message is posted on
the host server. These EMS messages relate to mount requests, VTSPolicy commands, heartbeat
messages, and critical and error event messages.
Note For a list of EMS messages, see "EMS messages" on page 199.
Perform the following steps for each NonStop host server to which VTS will send messages.
Before beginning
l Create a user account on the host server that can be used by the EMS distributor.
