HP D2D100 Backup System - Manual (Page 69)

Table 4 Cartridge parameters
Location
The Location column identifies each element of the autoloader that is available to
hold a cartridge. There are three elements:
• Slot n: which is one of the standard autoloader 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 indicates that a physical cartridge is inserted in an attached
tape drive and is ready for import.
Bar Code:
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.
Used Size:
This shows the actual used capacity in MB or GB. If this is Blank, the cartridge
may be removed, see below.
Max Size:
defaults to 200 GB. This value may be changed if the Used Size is Blank, see
below. The maximum value allowed is 800 GB.
Write Protected:
is a check box that allows you to enable (checked) and disable (unchecked) write
protection, see below.
Last Written:
tells you when the cartridge was last written to and is useful when identifying data
for copying or exporting.
Empty slots
Empty slots are slots that contain no cartridges; all the fields contain dashes or hyphens.
• Tape drive row: An autoloader consists of two devices; a tape drive and changer device. This
location refers to the tape drive element of the autoloader. It is only populated when the backup
application on the host is writing to or reading from the autoloader.
• 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.
• 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 Remove 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 button is available to create a new, blank cartridge.
See “ To create a cartridge ” on page 70.
To remove a cartridge
If the Used Size of a cartridge is Blank, you will be able to remove it. Click on the Remove button. This
button is not displayed, if the cartridge is not blank.
