Virtual TapeServer 6.03.42 Operations and Administration Guide

118 | Troubleshooting
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 of
hard drives and reseat them individually. Be sure to properly shutdown VTS before
performing this operation.
File system
Verify the following:
• Has anything changed?
• Is performance slow?
• Is GFS or NFS running on the system?
• Is the problem occurring for a particular vault or all vaults? Is the problematic vault on
internal or external disk storage?
• What is the result of the last vault check on the external storage?
You can check for FSCK messages in the system log, as well as the result of the last vault
check.
