Troubleshooting
This appendix provides information to assist you in addressing problems you may encounter
while installing and using Virtual TapeServer (VTS). If you cannot solve an issue using this
information or if you must contact Support, gather the following information:
• VTS model number
• The operating system and firmware versions of the VTS server
• The version of VTS, which can be found on the System Status page
• Whether external storage is attached to VTS (disk array, network attached storage, and
so on)
• The symptom of the problem
• The last time VTS functioned properly
• The task (backup, restore, export, and so on) that was occurring at the point of failure
• Debug, system, and EMS log files
Common issues and diagnostic techniques
The following sections provide general information to diagnose hardware components and
software features of the VTS system.
NonStop server
If error 190 occurs on the Subsystem Control Facility (SCF) on the NonStop server, perform
the following:
• Check power on VTS.
• Check SCSI converter. (Blue LED indicates power is on.)
• Check SCSI cable connections for bent or loose pins.
• QTOS users must stop QTOS process before stopping or starting a virtual tape drive from
SCF.
If error 224 occurs on the SCF, perform the following:
• Verify virtual tape is 519X or 5257 definition.
• Confirm emulation by checking debug.log for [filter] entry.
• Verify that the WWPN, SAC, and Module are correctly listed in SCF for the tape device.
If an “end of media” message is displayed on the host, perform the following:
• Check the System Overview page to find the virtual tape device in question.
• Erase expired virtual tapes to clear disk space.
