Data security on WORM mediaEdit onlineCertain built-in security measures help ensure that the data that is written on a WORM cartridge does not become compromised.For example:The format of an Ultrium WORM Tape Cartridge is not the same as the standard read/write media. This unique format prevents a drive that lacks WORM-capablefirmware from writing on a WORM tape cartridge. For LTO 9, native data capacity is 18 TB and compressed data capacity is 45 TB.When the drive senses a WORM cartridge, the firmware prohibits the changing or altering of user data that is already written on the tape. The firmware notes thelast point on the tape that can be appended.WORM media errorsEdit onlineSeveral conditions can cause WORM media errors to occur.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 notmatch, a media Error Code posts on the drive's single-character display (SCD).Inserting a WORM tape cartridge into a drive that is not compatible with WORM causes the cartridge to be treated as an unsupported medium. The drive reports amedia Error Code . Upgrading the drive firmware to the correct code level resolves the problem.WORM requirementsEdit onlineYou can add WORM capability to your IBM® Ultrium tape drive.To add WORM capability to your IBM LTO Ultrium 9 drives, you must use IBM Ultrium 9 WORM tape cartridges (18 TB), or IBM Ultrium 8 tape cartridges (12 TB). SeeOrdering media supplies.Cleaning cartridgeEdit onlineA specially labeled IBM® LTO Ultrium Cleaning Cartridge is used to clean the drive head.The drive itself determines when a head must be cleaned. It alerts you when the single-character display (SCD) flashes a . To clean the head manually, insert a cleaningcartridge into the tape load compartment. See Figure 1. The drive completes the cleaning automatically. When the cleaning is finished, the drive ejects the cartridge, andthe SCD is blank.Note: The drive automatically ejects an expired cleaning cartridge without running the cleaning process. Replace the expired cleaning cartridge with a new cleaningcartridge and insert it into the drive.The IBM cleaning cartridges are valid for 50 uses. The cartridge's LTO-CM chip tracks the number of times that the cartridge is used.Important: After 50 uses, the cleaning cartridge expires. It is no longer usable, and must be replacedCartridge memory chip (LTO-CM)Edit onlineAll generations of the IBM® LTO Ultrium Data Cartridges include a Linear Tape-Open Cartridge Memory (LTO-CM) chip.The Linear Tape-Open Cartridge Memory (LTO-CM) chip ( 1 in Figure 1) holds information about that specific cartridge, the media in the cartridge and the data on themedia. The LTO-CM enhances the efficiency of the cartridge. For example, the LTO-CM stores the end-of-data location. When the cartridge is inserted and the Writecommand is entered, the drive can quickly locate the recording area and begin recording. The LTO-CM also aids in determining the reliability of the cartridge by storingdata about its age, how many times it was loaded, and how many errors it accumulated. When you unload a tape cartridge, the tape drive writes any pertinent informationto the cartridge memory.The storage capacity of the Generation 9 LTO-CM is 32640 bytes. This capacity is double that of Generations 6, 7, and 8 LTO-CM (16320 bytes), and four times thecapacity of Generations 5 and 4 LTO-CM, which is 8160 bytes. LTO Generations 1, 2, and 3 have an LTO-CM capacity of 4096 bytes.IBM TS22xx - TS2290, TS2280, and TS2270 37
