Determine the Required Number of Reserved System Slots

Reserved system slots store diagnostic and cleaning cartridges. The number of required slots depends on your cleaning strategy and diagnostic needs. You can reserve up to a maximum of three slots.

• Diagnostic Cartridge — may require 1 reserved slot.

  If you are planning to use a diagnostic cartridge, Oracle recommends that you configure one reserved system slot to hold it. This insures that it is always available when needed. But if storage space is at a premium, you can also import the diagnostic cartridge from the mailslot as needed.

• Cleaning Cartridge — may require 2 reserved slots.

  If using library auto cleaning or manual cleaning: configure at least one, preferably two reserved slots. Two cleaning cartridges in reserved slots minimizes downtime by insuring a usable cleaning cartridge is always available, so drives do not sit idle while awaiting cleaning.

  If using host-managed cleaning: do not configure system reserved slots for cleaning cartridges. Host applications cannot access system reserved slots. Cleaning cartridges must reside in storage slots controlled by the host application.
