Virtual TapeServer 6.04.01 Installation Guide

Troubleshooting | 117
If error 224 occurs on the SCF, perform the following:
• Verify that the virtual tape is using the 519X or 5257 definition.
• 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, erase expired virtual tapes to clear disk
space.
If a tape drive stops responding from SCF, perform the following:
• Check the system log for parity errors or other SCSI-related failures.
• Check power indicators on the SCSI converter.
• Check that the virtual tape is connected to a logical device on the System Overview page.
VTS server module
You can troubleshoot various areas of the VTS server module.
Host server
Verify the following:
• Is the server powered on?
• Are the lights on?
• Are all of the cables secured tightly?
• Are any pins bent on any of the cables?
• Are all of the PCI cards seated properly? Is the plastic clip secured for each?
• Are messages present in the Power On Self Test (POST)?
If necessary, reseat the PCI cards. Halt VTS from the web interface, power down the server,
unplug the power cord, and then remove cables and reseat the PCI cards.
Hard drives
Verify the following:
• Are the hard drives seated properly?
• What is the color of the drive LED?
A green LED indicates normal operation; amber indicates failure. You can also remove all
hard drives and reseat them individually. Be sure to properly shut down VTS before
performing this operation.
SCSI controllers
You can rescan all SCSI controllers and list the devices. Be sure to stop the tape drives in SCF
on the host server before initiating the scan. Use the following commands to rescan the SCSI
controllers:
cd /usr/local/tape/bin
./rescan-scsi-bus.sh -l -c -r -w
Output is listed on screen and in the /usr/local/tape/log/rescan.txt file. The VTS
application must be restarted when a new physical tape device is found and must be used.
If the new devices were not detected, you can unplug the Fibre Channel connection to the VTS
server for two minutes or reboot the system.
