WRITE ONCE, READ MANY

(WORM) CAPABILITY

OVERVIEW

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 1x7 LTO Autoloader when you have an LTO-3 tape drive installed.

Note:Only the LTO-3 tape drive has 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 131 to determine the firmware requirements.

WORM MEDIA

Because standard read/write media are incompatible with the WORM feature, a specially formatted WORM tape cartridge (see Figure B-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.
