4.2.7 Activating the Autoclean Function
The autoclean function is disabled by factory default.
I Depending on the backup application used on your host you can decide,
if this software should manage the cleaning of the library’s tape drive, or
if it will be cleaned by activating the autoclean function.
After enabling autoclean, the autoclean process automatically starts when a
cartridge is unloaded from the tape drive that reports “cleaning requested“. For
cleaning the drive the library can use every previously in an inventory identified
cleaning cartridge. A cleaning cartridge must have a “CLN” bar code label to
work with the autoclean function.
To activate the autoclean function:
1. In the Home Screen of the OCP, select Configuration → Configure Library →
Autocleaning Disabled.
2. Press Enter twice.
A cleaning cartridge will not be used once it has exceeded its maximum count
of operations (50 loads) or when a medium error was detected during operation.
If there is more than one cleaning cartridge available, the one with highest load
count will be used. This causes the cleaning cartridge with the highest load
count to wear out first.
4.3 Magazines
Cartridges are stored in magazines. Up to 4 cartridges can be stored in each
magazine. Magazines may be removed and inserted individually.
The ETERNUS LT20 LTO library has two magazines in the 1U library (see figure
24 and figure 29). Magazine access can be password protected. For safety
reasons, the robot motion is stopped when a magazine is removed. See section
“Changing the Administrative Password” on page 67.
The magazines can be released using the Operator Control Panel (OCP) or the
Remote Management Unit (RMU).
In case the OCP or RMU initiated process has failed or the library no longer has
power, a manual emergency release is available. See section “Magazine Does
not Unlock via OCP or RMU” on page 96.
