Virtual TapeServer 6.03.41 Installation Guide

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

• The uptime on the system (available from the command line of the operating system)

Common issues and diagnostic techniques

The following sections provide general information to diagnose hardware components and

software features of the VTS system. For diagnosing problems, the following tools may be

helpful:

• PuTTY (Telnet/SSH client), which is A GUI-based application to issue Telnet, SSH, and

other connection commands to a host server. You can download PuTTY from

http://www.chiark.greenend.org.uk/~sgtatham/putty/.

• Virtual Network Computing (vnc) remote control software, which enables you to remotely

access the console of a UNIX server. VNC must be configured on the host server before

you can use it from a client. You can download VNC from

http://www.vnc.com/.

NonStop server

If error 190 occurs on the Subsystem Control Facility (SCF) on the NonStop server, perform

the following:

• Check the power on VTS.

• Check the SCSI converter. (Blue LED indicates power is on.)

• Check the SCSI cable connections for bent or loose pins.

• QTOS users must stop the QTOS process before stopping or starting a virtual tape drive

from SCF.
