Methods of cleaning drives

Automatic cleaning of tape drives is disabled by default in the library. However, automatic cleaning of
tape drives is recommended for this library. It is also possible to initiate manual or host cleaning
methods.
The head of every tape drive in the tape library must be kept clean to prevent errors that are caused by
contamination. To help you keep the drives clean, Dell provides a cleaning cartridge with the library. The
library uses the cleaning cartridge to clean the drive with whatever cleaning method that you choose. In
all methods, cleaning is done after the data cartridge is unloaded from the drive and before the next load.
It is the operator's responsibility to monitor cleaning cartridge usage and replace cleaning cartridges as
necessary. This tape library provides multiple ways to monitor and manage cleaning cartridges. If SNMP
traps are enabled, a trap is generated when a cleaning cartridge expires. It is also possible to use the
Management GUI to monitor the cleaning cycles that remain on a cleaning cartridge and to the enable a
setting that automatically ejects expired cleaning cartridges.
Three methods of cleaning are available.
Automatic cleaning
Automatic cleaning enables the library to automatically respond to any tape drive's request for
cleaning and to begin the cleaning process. The cleaning process is transparent to any host
application that uses the library.
Select Auto Clean to enable the auto cleaning feature. When enabled, the library automatically
initiates a cleaning operation when media is unloaded from a drive that requires cleaning instead
of creating a warning event when a drive requires cleaning. For reliable operation, enable Auto
Clean for each logical library and ensure that the library has a valid cleaning cartridge.
When a cleaning operation is initiated, the library first attempts to use an unexpired cleaning
cartridge from the same logical library as the tape drive. If the logical library does not contain an
unexpired cleaning cartridge, the library attempts to use an unexpired cleaning cartridge from a
storage slot that is not assigned to a logical library. The library does not use a cleaning cartridge
from a different logical library. When auto cleaning is enabled, ensure that each logical library has
an unexpired cleaning cartridge. Or, place at least one unexpired cleaning cartridge in a storage
slot that is not assigned to a logical library.
After the initial configuration, Auto Clean can be turned on or off by accessing the Logical
Library Wizard Expert Mode.
1. Go to Library > Logical Libraries > Actions > Manage Logical Library (Expert Mode).
2. Select the logical library, then click Edit.
3. Click Next to go to the General Settings screen.
4. Check or clear Auto Clean, then click Next on the subsequent screens.
5. If a change was made, click Finish and the Logical Libraries are reconfigured. If no changes
were made, click Cancel.
