Chapter 4 - Maintenance 73
Chapter 4 — Maintenance
The only maintenance task that should be periodically performed by the user is to run the
cleaning cartridge. The system will notify you when a drive needs cleaning. Occasionally, new
firmware is issued by Overland Data. Firmware upgrades must be performed by qualified
service personnel.
The Maintenance Menu offers the following options:
•
Clean Drive
•
Diagnostic Menu
•
Demo Menu
•
Flash Update
•
Flash All Slaves
•
Novram Update
•
Clock Update
•
Flash DLT
•
Reboot Module
Of these, only Clean Drive and the Demo Menu are intended for the user. Diagnostics and
flash updates of firmware should be performed only by service personnel. This chapter tells
you how to clean the drives and how to update the firmware in the flash PROMs. The Demo
Menu is described in Chapter 5 - Troubleshooting.
Cleaning Cartridge
The cleaning cartridge is similar in appearance to the cartridge shown in Figure 3-43. The
command to run the cartridge is issued from the control panel of the Global Control Module.
The procedures that follow tell you how to install a cleaning cartridge, how to clean a drive,
and how to remove the cleaning cartridge.
The default location for a cleaning cartridge is slot 1. That is, unless you specify a different
slot when you start a cleaning operation, the system will look for the cleaning cartridge in slot
1. A cleaning cartridge can be run from any slot in any module.
Note: The cleaning cartridge is abrasive, and should not be used unless the
Use Cleaner
LED
comes on one of the slave modules. To determine which drive requires cleaning, unload all of
the drives in that module and select ‘Cleaning Needed’ on the Drive Status submenu. See the
section headed ‘When to Run the Cleaning Cartridge’ later in this chapter.
Required Location for the Cleaning Cartridge
Generally, there are no restrictions on the location of the cleaning cartridge. However, if 1)
you have designated a mail slot, or 2) you are using the reserved slots option, any
undesignated slots in the mail slot magazine or the reserved magazine become inaccessible to
the system. In these cases, the system designates one of these inaccessible slots as a cleaning
cartridge slot. On line 4 of the screen shown in Figure 4-3, ‘Cleaning Slot 1’ appears instead
of ‘Slot1.’ The question is where is Cleaning Slot 1 located. The answer is as follows.
