the drive. Replace the cleaning cartridge when all the boxes are checked. New cleaning cartridges are available from HP. 1. Insert a cleaning cartridge into the drive. The tape drive automatically loads the cartridge and cleans the heads. The Clean LED remains flashing and the Ready LED starts to flash. At the end of the cleaning cycle, the Clean LED turns off and the drive ejects the cartridge. The cleaning cycle takes approximately 30-60 seconds. 2. Remove the cleaning cartridge from the drive. The drive's TapeAlert feature will send a message to your backup application when the tape heads need cleaning or a cleaning cartridge has expired. Expired cleaning cartridges HP StorageWorks DAT 320 drives: If an expired cleaning cartridge is placed into the drive, the Clean LED remains flashing, and the Ready LED and Tape LED start to flash. The expired cleaning tape ejects automatically. (The Ready LED turns off, the Clean and Tape LEDs continue to flash. Discard the cleaning cartridge). Recovery from this condition is to insert a good cleaning cartridge. (The Tape LED will turn off immediately.) HP StorageWorks DAT 160 and DAT 72 drives: If the cleaning cartridge is not ejected, it has probably expired. In this case, press the Eject button, discard the cleaning cartridge and repeat the operation with a new one. Handling 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 ex- ample, under telephones, next to monitors or near transformers). • Do not drop cartridges or handle them roughly. • Do not stick more than one label onto the cartridge label area; extra labels can cause the cartridges to jam in the drive. Stick labels onto the label area only. • See the insert included with the tape cartridge for storage conditions. Getting the most out of cartridges and drives • Use mostly the matching media type (DAT 320 media for HP StorageWorks DAT 320, DAT 160 media for HP StorageWorks DAT 160). • Use media for the recommended number of times (DAT 320, DAT 160=100 full backups). Overuse of the tape will cause it to degrade and possibly shed tape debris in the drive. Too many new tapes can also cause wear of the drive as they are rougher than used ones. • Do not verify (DDS does read-after-write checking automatically). • Do not overload the server during backups. Maximize the transfer rate (run overnight with no other processes) and use incremental backups if convenient. • Do not overuse your tape drive-it is designed for approximately three hours of tape pulling per day, not constant usage-and clean the drive regularly. See "Cleaning cartridges" on page 69. • If you want to bulk erase cartridges, this should be done in a controlled environment. You need to make sure there are no other cartridges with sensitive information on them anywhere near the bulk eraser when in use. All data will be lost on cartridges that are bulk erased. 70 Use the correct media
