Troubleshooting
This section includes information about how to troubleshoot problems and notes about items 
that may need clarification.
Installation, upgrades, updates, and restore
 No disk space available after an upgrade. After an upgrade, there exists the potential 
to exceed the amount of available disk space. (TL-3885)
WORKAROUND: Regularly remove unused files, such as those located in the /tmp and /
var/log directories.
 /usr/local/tape/log/vts-post-install.log contains FATAL error messages. The VTS 
installation log, /usr/local/tape/log/vts-post-install.log, contains FATAL error 
messages regarding missing modules.dep files. These messages can safely be ignored. 
(TL-2201)
Hardware and configuration
 Disk arrays are not properly detected after a rescan. Rescan of the buses fails to 
display the proper number of disks. This is a driver limitation; the QLogic driver shipped 
in the appliance is not detecting the device changes. (TL-5439)
WORKAROUND: Restart Tapeserver or reboot the server.
 Starting a VTD on the NonStop results in two errors logged to debug.log. 
Immediately after the NonStop command “SCF START TAPE $VTAPE00” is issued to 
start a virtual tape device, one or more of the following messages may appear on the VTS 
server in /usr/local/tape/log/debug.log:
Mon Jun 23 14:31:33 2008: [cli_tape 0x05000007] read ERROR on message 
rc = 1
These messages are benign and may be ignored. (TL-1802)
 Fibre Channel ports do not initiate link status and lasers are off if ports are set 
to target mode and VTDs are not defined. When a Fibre Channel port is enabled for 
target mode, the port will not initiate link status until a VTD has been defined on that 
port and the lasers will be off. The port will appear to be disconnected unless a VTD has 
been defined. Likewise, when Tapeserver is stopped, the Fibre Channel ports will drop 
link status, to emulate the function of a physical tape drive with the power turned off. 
(TL-2641)
 Must run /usr/local/tape/bin/grub-serial.bash to access GRUB from the console. 
When VTS boots, you must press a key when prompted if you wish to see the GRUB 
menu. The /usr/local/tape/bin/grub-serial.bash command will modify the system boot 
configuration to provide serial console access to the GRUB boot menu. This command 
must be run as root. In some cases, it may cause the system boot time to be greatly 
increased, although the normal boot time is only expected to increase by 10 seconds after 
running this command. (TL-2255)
 VTDs set as device type 519x show up as FUJITSU M2483B drives. According to 
the HP web site, the 5190 drive reports itself as a Fujitsu drive. (TL-1107)
