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, 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 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. Launch a web browser, if necessary, and access the VTS web interface.
3. If necessary, log in 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.
4. Enable EMS and configure the general settings, as follows:
a. Click Supervisor Functions on the navigation pane.
b. Click the Edit EMS Configuration link. The EMS Configuration page is displayed.
