Note
To initiate the cleaning cycle manually you must be aware of the present state of the Scalar Library and the drive that you wish to clean.
If a cartridge is present in the drive, you must first press the UNLOAD button on the drive front panel, then, when the OPERATE HANDLE LED is illuminated, open the drive door and remove the cartridge. You can then proceed with these instructions.
If the drive is empty, but the door is closed, make sure that the
OPERATE HANDLE LED is illuminated before opening the door.
You may then proceed with these instructions.
If the drive is empty, and the door is open, proceed with these instructions.
❐Open the front door of the Scalar Library.
Note
You can manually move the Media Picker assembly right or left to provide access to the drives. Avoid manually moving the Media Picker assembly up or down.
❐Insert the cleaning cartridge into the drive you wish to clean. Close the drive door handle.
The cleaning cycle will be performed. When cleaning is completed, the drive will unload the cleaning cartridge. Remove the cleaning cartridge and check a usage box on the label.
❐To resume normal operation, close the door and lock it.
Causes of the Use Cleaning Tape Warning
The most common reasons that the Use Cleaning Tape LED gets turned on for, in order of highest rate of occurrence, are listed below:
∙Dirty ("Stained") heads.
A cleaning cycle must be executed to clear this indication.
∙Worn tape.
DLT tapes are rated at 500,000 passes. Applications that overwrite small blocks of data cause "shoe shining" of the tape against the head and will reach the 500,000 passes sooner than might be expected.
∙Bad environment.
Data errors result from a number of factors, each of which subtract from the margin between good data recovery and an error. High levels of dust contamination, high humidity, and heat can be significant factors.
