Problem Solution
Cartridge VOLSER is reported
as "unknown" Probable cause: cartridge with no label or damaged label.
Ensure that cartridge is properly labelled. If cartridge is properly labelled, unload
the cartridge from drive and perform an inventory (OCP: Control > Re-Inventory;
Web: Manage Library > Perform Inventory). If VOLSER is again reported as
"Unknown", run Library Verify (Service > Library Verify).
DRIVE ID (SCSI, SAS, OR FIBRE CHANNEL LOOP)
Changed drive ID, but the host
server does not recognize the
new ID
1. Ensure that all devices on the same bus/network have unique ID numbers.
2. Ensure that you cycle power on the library after changing the ID.
3. Reboot the host server.
Tape library performance: The
library is not efficiently backing
up data
1. Check the network bandwidth from the host computer. If you are backing up
data over a network, consider comparing to a local-only backup.
2. Ensure that the library and tape drive are on their own SCSI bus and not
daisy-chained to another tape drive or to the hard drive being backed up.
3. Ensure that the library is connected to a LVDS SCSI bus and there are no
single-ended (SE) devices on the same bus, because this will cause the entire
bus to negotiate down to SE speed.
4. Use an Ultra160 SCSI bus and high-quality cabling with the library.
