February 2003 This document was produced for your tape drive or library vendor by Hewlett-Packard. The information contained in this document is subject to change without notice. [. . . ] We recommend Ultrium 400 GB tape cartridges for use with your tape drive (assuming 2:1 compression). Write-protecting cartridges If you want to protect the data on a cartridge from being altered or overwritten, you can writeprotect the cartridge. Always remove the cartridge from the tape drive before you change the write protection. · To write-protect a cartridge, slide the red tab by the label area on the rear face of the cartridge to close the hole. Note the padlock on the tab that indicates that the cartridge is protected. · To write-enable a cartridge, slide the red tab back so that the hole is open before loading it into the drive. Write-protection will not prevent a cartridge being erased by bulk-erasure or degaussing. This will destroy pre-recorded servo information and make the cartridge unusable. Cleaning cartridges You must use Ultrium cleaning cartridges with Ultrium Generation 2 tape drives, as other cleaning cartridges will not load and run. Unlike some earlier Generation 1 Ultrium cleaning cartridges, the orange colored Ultrium Universal cleaning cartridge is designed to work with any Ultrium compliant drive. Do not use other format cartridges in your tape drive and do not use Ultrium cartridges in other format tape drives. To clean the tape drive: A cleaning cartridge is supplied with each tape drive and should only be used when the orange Clean LED is flashing. 1 2 Insert the cleaning cartridge. The drive will carry out its cleaning cycle and eject the cartridge on completion (which can take up to 5 minutes). During the cleaning cycle the orange Clean LED will be on solidly and the green Ready LED will flash. If the cleaning cartridge is ejected immediately with the Tape Error LED on, it has expired. 25 Looking after cartridges · Do not touch the tape media. · Do not attempt to clean the tape path or tape guides inside the cartridge. · Do not leave cartridges in excessively dry or humid conditions. Do not leave cartridges in direct sunlight or in places where magnetic fields are present (for example, under telephones, next to monitors or near transformers). · See the insert included with the tape cartridge for storage conditions. 26 Optimizing performance Various factors can affect tape drive performance, particularly in a network environment or if the drive is not on a dedicated SCSI bus. If your tape drive is not performing as well as expected, consider the following points. Is the tape drive on a dedicated SCSI bus? For optimum performance, we recommend that the tape drive is the only device on the SCSI bus. If they are single-ended, the bus will switch to single-ended mode with a lower transfer speed. There will also be restrictions on cable length. Can your system deliver the required performance? The Ultrium Generation 2 tape drive can write data at 30 MB/s (native) or 60 MB/s (compressed - assuming 2:1 compression), however, to get this performance it is essential that your whole system can deliver this performance. Typical areas where bottlenecks can occur are: · Disk system (a single hard disk drive will not be able to deliver 60 MB/s transfer rates). · Some file systems are able to transfer data faster than others. · The type of data being backed up can affect backup performance (for example, file sizes and compressibility). [. . . ] Do not reset or power cycle the drive. Firmware is being reprogrammed. Clean is FLASHING. The drive requires cleaning. Load the Ultrium cleaning cartridge. If the clean LED is still flashing when you load a new or known data cartridge after cleaning, call for service. The cleaning cartridge will eject on completion. The cleaning cycle can take up to 5 minutes to Cleaning is in progress. complete. Ready is FLASHING and Clean is ON. Unload the tape cartridge. [. . . ]
