Configuring EMS Communication
To automate the process of mounting and dismounting virtual tapes, you must configure the
Event Management System (EMS) on Virtual TapeServer (VTS). The EMS service starts the
EMS distributor on the NonStop 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 NonStop server. These EMS messages relate to mount requests, VTSPolicy
commands, TACL heartbeat messages, and critical and error event messages.
Perform the following steps for each NonStop server to which VTS will send messages.
Requires the Edit VTS Configuration File access right to edit the configuration file, and
System Maintenance Functions or Virtual Tape Mounts and Locks access right to restart the
EMS service
To configure EMS
1. On the NonStop server, create a user account that VTS can use for the EMS distributor.
2. On VTS, modify the VTS configuration file to configure EMS, as follows.
Note A default configuration file is defined for each VTS server. To override the default
settings, you must define settings as described below. Technically, you do not edit
the VTS configuration file; you simply define parameters that override those set in
the configuration file.
a. Click Supervisor Functions on the navigation pane.
b. Click Edit VTS Configuration File.
