Virtual TapeServer 8.0 Configuration Guide

Configuring EMS Communication
To automate the process of mounting and dismounting virtual tapes, you must configure the
Event Management System (EMS) on the Virtual TapeServer (VTS) server. The EMS service
for NonStop servers 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, heartbeat messages, and critical and error event
messages.
Note For a list of EMS messages, see EMS messages on page 152.
Perform the following steps for each NonStop server to which VTS will send messages. The
full procedure is documented in the online help, which is accessed by clicking the Help button
on the EMS Configuration page of the VTS web interface.
Requires the Edit Configuration File access right to edit the EMS settings, 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. Log in to the VTS web interface using an account that is assigned the access rights listed
above. Click the Log In button at the top of the page and enter a username and password.
