If the problem still exists, contact technical support.EncryptionEncryption Error: Displayedwhen the drive detects an errorassociated with a encryptionoperation - if the problemoccurred while the tape drivewas writing data to, or readingdata from, tape1. Check the host application to ensure the host application is providing thecorrect encryption key.v Refer to the Dell Tape Device Drivers Encryption Support documentationand the Dell LTO Ultrium Tape Drive SCSI Reference documentation for theSense Data returned for an encryption operation.v Retry the encryption operation after the host application problems havebeen resolved.2. Check the operation of the tape drive by resetting the drive and runningPOST.v Refer to the error code displayed on the SCD if the drive resets and POSTfails.v Retry the encryption operation if the drive reset and POST complete withouterrors.3. Check the media.v Ensure the correct media is being used. Data encryption is supported withLTO Ultrium 4 Data Cartridges only.v Retry the encryption operation with the tape cartridge in another encryptionenabled drive. Replace the media if the problem repeats with the same tapecartridge in multiple drives. If the problem occurred while the tape drivewas running POST or diagnostics, replace the drive. The error code clearswith the first attempted write/read after the encryption key is changed, orwhen the drive is placed in maintenance mode.
