• Erasing all virtual tapes in a pool on the Cartridge Maintenance page:
A message similar to the following is displayed on the web interface:
Erased 1 cartridge; Erasure of cartridge SH0002 in pool SHARE failed!
• Setting the virtual tape size on the Pool Maintenance page:
A message similar to the following is displayed on the web interface:
Unable to set size limit on SHARE:SH0001, rc=2. Operation aborted!
After the operation aborts for the encrypted tape, any tapes for which this operation is
attempted will also fail.
You can also check /usr/local/tape/log/SecureVTS.log, which logs all tape operations
associated with encryption. Go to the bottom of the log to look for problems.
Event log file
VTS provides many log files for troubleshooting issues with various functions of the system.
For example, the EMS log contains all messages (dependant on filters) received from the
NonStop server and the responses sent from VTS. VTS adds text that describes successful or
unsuccessful mounts, VTSPolicy commands that were interpreted, and so on. This file enables
you to diagnose the EMS configuration to and from the NonStop. For example, the log shows
the error that the password is invalid or the IP address did not connect. The event.log file
resides in /usr/local/tape/log on the VTS server.
The system event log file is generated by the VTS operating system (Linux) and records
information about events such as the creation and deletion of virtual tapes, failures of
processes and services, and the status of jobs and policies. The messages are stored in a single
log file, which is plain text and viewable from the user interface. The messages include
information about the time and date of the event as well as the name of the user who initiated
the event. Use the messages in this file to detect problems, track down the source of faults,
and audit users. In addition, information in the system event log can be retrieved by third-
party applications, such as Prognosis or Insight Manager, for notification purposes.
Requires the View log files access right

•Click Refresh to refresh the log.
•Click Top to view the top of the log (and the oldest entries).
•Click Download to save the entire file to a local directory.
•Click Previous or Next to page through the file.
Location, retention, and rotation
The /usr/local/tape/log directory contains the current log file, which is named event.log, as
well as the previous 30 log files. The event log is rotated, or “aged,” the same as the other log
files. Log aging is set up to check daily if a log file has reached a size greater than 10KB. If the
size limit is reached then the old log is renamed to a new name containing the rotation
