ValueLoader Performance
The ValueLoader is not
efficiently backing up data.
• Check the network bandwidth from the host computer. If you
are backing up data over a network, consider comparing to a
local-only backup.
• Make sure the ValueLoader is on its own SCSI bus and not
daisy-chained to another tape drive or to the hard drive being
backed up.
• Clean the tape drive. See
Cleaning the Tape Drive
on page 32.
• Try a new cartridge. A marginal cartridge can cause
performance problems due to bad spots on the tape requiring
retries.
• Make sure the data is being compressed.
• Check the size of the files. Small files can impact performance.
• Confirm that the backup application is utilizing block sizes of
at least 32 KB, preferably 64 KB. Refer to your application’s
documentation for details.
Cleaning
Recurring cleaning
message.
• Make sure you are using an HP LTO cleaning cartridge.
• Replace the existing cleaning cartridge with a new one.
• If the Media Attention LED is cleared using a cleaning
cartridge and then immediately reappears after a particular
data cartridge is reloaded, that data cartridge may
contaminated. If this occurs, check that the data cartridge can
be read, back up data from the suspect cartridge to another
cartridge, and then discard the suspect cartridge.
The Clean Drive LED is
illuminated.
• This indicates that you have exceeded the tape motion hours.
• Clean the tape drive. See
Cleaning the Tape Drive
on page 32.
Cannot load the cleaning
cartridge.
• Make sure you are using an HP LTO cleaning cartridge.
• Contact your service representative.
