Virtual TapeServer 8.0 Configuration Guide

Troubleshooting | 131
Event Management System (EMS)
Verify the following:
• Has the EMS logon expired?
• Is there network connectivity between VTS and the NonStop server?
• Was the VTS operating system or the EMS template upgraded?
• Is VTS up-to-date with the latest product enhancement code?
• Is there a typographical error in the VTS configuration file?
You can check the EMS log file for the last timestamp of messages.
If EMS auto-mounting is not functioning, perform the following:
• Check the TACL user ID for access privileges.
• Check the Ethernet cable.
• Check Ethernet connectivity and activity LEDs.
• On the Manage System Tasks page of the VTS web interface, click Stop EMS Service, and
then click Start EMS Service to restart the EMS auto-mounting service.
• Verify that the virtual tape drives are available and that the virtual tape exists and is not
in use. The requested virtual tape may be in an autoloader that is currently in use.
• From the NonStop server, enter STATUS *, USER (username) to see if the EMSDIST
process is active.
•Check /usr/local/tape/log/ems.log. Go to the bottom of the log to look for problems.
• View the Virtual Media - Mounts and Locks page. View the list of locked virtual tapes. If
you are certain that a particular virtual tape is not in use but VTS indicates that it is
locked, remove the lock here.
Virtual tape operations
If you are unable to manually mount a virtual tape, perform the following:
• Check the color of the virtual tape label. Gray indicates the virtual tape is in use by
Import/Export or is remotely mounted.
• Verify that the autoloading library containing the virtual tape is not in use.
• Verify that Data Encryption is enabled and configured properly in a cluster environment.
The mount will fail, for example, if the key server is not configured on all servers.
If virtual tapes are mounted as read-only or write failures occur, verify that licensing has not
been exceeded (for the VTD or Capacity license).
If you cannot import a physical tape, perform the following:
• Check the tape drive for power.
• Check the tape drive for tape ready indicators.
• Check the SCSI cable to the tape drive.
• Check file system Free (Pct).
If you cannot export a virtual tape or an export failed, perform the following:
• Check the tape drive for power.
• Check the tape drive for tape ready indicators.
• Check the SCSI cable to tape drive.
