Virtual TapeServer 6.03.42 Operations and Administration Guide

120 | Troubleshooting
Software features
Check the System Status page to confirm that all virtual tape devices are listed. This ensures
that VTS is presenting each virtual tape device and indicates which devices are running.
The following sections may help you diagnose problems with various software features of
VTS.
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 TACL user ID for access privileges.
• Check the Ethernet cable.
• Check Ethernet connectivity and activity LEDs.
• Click RESTART on Mount Maintenance.
• Verify that the virtual tape drives is 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 EMSDIST process
is active.
•Check /usr/local/tape/log/ems.log. Go to the bottom of the log to look for problems.
• A keying error occurred on the restore or backup.
• 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 SecureVTS 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 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).
