Empty slots

Empty slots are slots that contain no cartridges; all the fields contain dashes or hyphens.
• Tape drive row: A library consists of two devices; a tape drive and changer device. This location
refers to the tape drive element of the library. It is only populated when the backup application on
the host is writing to or reading from the library.
• Mail slot row: This location refers to the slot that is used for importing and exporting data.
It is only populated:
• When the backup application on the host moves data into it for export to a tape drive
attached to the HP D2D Backup System. Once the export has been run successfully from the
Web Interface, the slot becomes empty again.
• Or when the Web Interface is used to import data from a tape drive attached to the HP
D2D. The backup application on the host is used to move the data back into a numbered
slot and the mail slot becomes empty again.
• Numbered slot row: This slot is empty after a Delete operation or after the backup application
has moved data to the mail slot for export.
Once a mail slot or numbered slot is empty, a Create icon is available in the far right column to create
a new, blank cartridge. See
The Location column identifies each element of the library that is available to hold a
cartridge. There are three types of element:
Slot n: which is one of the standard library slots
•
Mail slot: which is a dedicated slot that is used to hold a cartridge that is ready
•
for exporting to or importing from physical tape. Cartridges can only be moved
into the mail slot by the backup application on the host machine.
• Tape drive: which is only populated when there is activity on a cartridge.
A bar code is an 8–digit, alphanumeric, unique identifier for a cartridge within
the HP D2D Backup System. Bar codes are shared with the backup application,
if requested. The backup application may also choose to assign its own internal
identifier to the cartridge but, if it does so, it cannot assign this identifier to the
Cartridge bar code.
Bar codes are generated automatically but may be edited by the user. If you
choose to edit the bar code:
• It must be unique and must not start with the letters "CLN" or "DG" because
these are reserved designations for cleaning and diagnostic cartridges.
• It should be a minimum of 4 characters. Valid ASCII characters are A-Z, a-z,
0–9, space and hyphen. Anything less than 8 characters will be appended
with space characters.
This shows the actual used capacity in MB or GB. If this is Blank, the cartridge
may be removed, see below.
This defaults to the appropriate capacity for the drive emulation type selected on
the Devices tab. This value may be changed if the Used Size is Blank, see below.
The maximum value allowed is 800 GB.
This is a check box that allows you to enable (checked) and disable (unchecked)
write protection, see below.
This tells you when the cartridge was last written to and is useful when identifying
data for copying or exporting.
This allows you to mark a cartridge for deletion, which may free up space on the HP
D2D. If deduplication is enabled on the library, only the space occupied by unique
data will be cleared. Space that contains blocks referenced from another slot, will
not be freed up. Deletion does not happen immediately; only after housekeeping
has been run. Housekeeping is a function that runs automatically when the disks
are not being accessed. It is not under user control.
