Virtual TapeServer 6.04.01 Operations and Administration Guide
Troubleshooting | 151
The Apache web server is responsible for running the VTS web interface. To verify that 
Apache is running:
/etc/init.d/httpd status
A message similar to the following should be displayed:
httpd (pid 25380 25015 25014 25013 25012 25011) is running...
Use the following commands, respectively, to stop, start, or restart the web server (halt VTS 
before issuing these commands):
• /etc/init.d/httpd stop
• /etc/init.d/httpd start
• service httpd restart
Note If you restart the HTTPD service using the /etc/init.d/httpd restart command, 
the owner is set to “apache” not “bill” and the web service (and interface) stops 
responding.
You can also reboot VTS to attempt to solve the problem.
Log files
The following log files may help you diagnose problems.
Operating system:
• /var/log/messages
• /var/log/cron
• /var/log/boot.log
Apache web server:
• /var/log/httpd/error_log
• /var/log/httpd/access_log
VTS:
• /usr/local/tape/log/ems.* (available from the VTS web interface)
• /usr/local/tape/log/debug.* (available from the VTS web interface; set the severity level 
by selecting Factory Setup
→Administrator Utilities→Set current debug level)
• /usr/local/tape/log/mount.log
• /usr/local/tape/log/export.log (available from the VTS web interface)
• /usr/local/tape/log/event.log (available from the VTS web interface; see page 154 for 
more information)
• /usr/local/tape/log/scanat.log
• /usr/local/tape/log/vtape.log
• /usr/local/tape/log/upgrade.log
• /usr/local/tape/log/ems.lastmount.cmd
• /usr/local/tape/log/rescan.txt

Note Though you can change the log level of these files, the log level is reset to the default 
every time VTS is rebooted.
