VERVIEW
Certain records retention and data security applications require a Write Once,
Read Many (WORM) method for storing data on tape. To meet this data
storage requirement, a new WORM feature is now available on the Magnum
224, StorageLibrary T24, or StorageLoader 2U LTO when you have an LTO-3
or LTO-4 tape drive installed.
Note: Only the LTO-3 and LTO-4 tape drives have WORM capability. It is not
available on the LTO-2 or LTO-1 tape drives.
No physical hardware changes are required to make the tape drive compatible
with the WORM feature; however, appropriate WORM-capable drive
firmware must be installed. See
“Requirements” on page 225 to determine the
firmware requirements.
WORM M
EDIA
Because standard read/write media are incompatible with the WORM feature,
a specially formatted WORM tape cartridge (see
Figure C-1 ) is required. Each
WORM cartridge has a unique, worldwide cartridge identifier (WWCID),
which comprises the unique CM chip serial number and the unique tape
media serial number.
