Web interface
If the web interface stops responding, verify the following:
• Access the interface from a different workstation.
• Ping the address.
• Check the Ethernet cable.
• Check Ethernet connectivity and activity LEDs.
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...
You can reboot VTS to attempt to solve the problem.
SCSI converter
During normal operation, the LEDs on the SCSI converter blink every 3-5 seconds. During
backups, the activity LED is almost solidly lit.
• Is the power turned on?
• Are all of the cables secured tightly?
• Are any pins bent on any of the cables?
• Are all four ports in use?
• Is normal communication occurring while SCF is running?
Be sure to stop the tape drive in SCF on the host server and power off the SCSI converter
before disconnecting cables.
External storage or the SAN
Verify the following:
• Is the storage array powered on?
• Are the lights on?
