58 StorageLoader Installation and User Manual
The tape loader responds on
the SCSI bus to the host, but
the tape drive does not respond
• Verify that the host application and the device drivers are
installed with the most resent patches to support the tape
drive
• Reboot the host system when the loader has completed its
power on sequence.
• Contact your service representative.
StorageLoader Performance
The StorageLoader is not
efficiently
backing up data
• Check the network bandwidth from the host system. If you
are backing up data over a network, consider comparing to a
local-only backup.
• Make sure the StorageLoader are on its own SCSI bus and
not daisy-chained to another tape drive or to the hard drive
being backed up.
• Verify that the host application and the device drivers are
installed with the most resent patches to support the tape
drive and the loader.
• Connect the autoloader to an LVD SCSI bus and make
sure there are no SE devices on the same bus, because this
causes the entire bus to negotiate down to SE speed.
• Clean the tape drive. See the installation and user guide,
chapter “Maintenance”, section “using the cleaning
cartridge”.
• Try a new cartridge. A marginal cartridge can cause
performance problems due to bad spots on the tape
requiring retries.
• Backing up compressed data lowers performance.
• Check the size of the files. Small file size can impact
performance.
Cleaning
Cannot load the cleaning
Cartridge
• Make sure there is no cartridge present in the drive before
you load a cleaning cartridge.
• Make sure the cleaning cartridge is not expired.
• Contact your service representative.
