WORM Media Errors
The following conditions cause WORM media errors to occur:
v
Information in the servo manufacturer's word (SMW) on the tape must match
information from the cartridge memory (CM) module in the cartridge. If it does
not match:
– a full-high tape drive will post a media Error Code
7 on the single-character
display (SCD).
– a library will post an error on the operator control panel
v Inserting a WORM tape cartridge into a drive that is not WORM capable causes
the cartridge to be treated as an unsupported medium. The drive will report a
media Error Code
7
. Upgrading the drive firmware to the correct code level will
resolve the problem.
Requirements for WORM Capability
To add WORM capability to your LTO Ultrium generation 3 or generation 4
drive(s), drive firmware must be at the correct code level, and you must use either
Ultrium 3 400 GB WORM tape cartridges or Ultrium 4 800 GB WORM tape
cartridges (see “Ordering Media Supplies” on page D-17).
Cleaning Cartridge
With each library, a specially labeled IBM LTO Ultrium Cleaning Cartridge is
supplied to clean the drive head. The drive itself determines when a head needs to
be cleaned. To clean the head, insert the cleaning cartridge into the tape load
compartment of the drive or the Input/Output (I/O) Station of the library. The
cleaning is performed automatically. When the cleaning is finished, the cartridge is
ejected.
Note: The drive will automatically eject an expired cleaning cartridge.
IBM Cleaning Cartridges are valid for 50 uses. The cartridge's LTO-CM chip tracks
the number of times that the cartridge is used.
Cartridge Compatibility

IBM Ultrium Tape Drive
IBM LTO Ultrium Data Cartridges
800 GB (Ultrium 4) 400 GB (Ultrium 3) 200GB (Ultrium 2) 100GB (Ultrium 1)
Ultrium 4 Read/Write Read/Write Read only
Ultrium 3 Read/Write Read/Write Read only
Ultrium 2 Read/Write Read/Write
Ultrium 1 Read/Write
Bar Code Labels
A bar code label contains:
v
A volume serial number (VOLSER) that is human-readable
v A bar code that the library can read
Note: The tape drive does not require bar code labels, but you may choose to use
labels for tape cartridge identification purposes.
