4. Conduct a backup and restore test to verify
that the drive can write data to tape. Use a
blank cartridge.
For operating systems that contain a native
backup application that supports tape devices,
you can use the native backup application to
test basic tape drive operation. Native backup
applications do not support all of the advanced
features of the tape drive so you will need to
test the advanced features with your backup
application. When testing with a third-party
application, upgrade the application before
running this test.
5. LTO-5 and later generation drives: If the server
is using StoreOpen with LTFS, verify that the
server has the latest LTFS software. If
necessary, download the latest version at:

Understanding the LEDs
1. On/Off switch (external drives only)
2. Eject button
3. Emergency reset button
4. Ready — green
On: the drive is ready for use
Off: the drive power is off or there was a failure during
self-test
Flashing: the drive is reading/writing data or
rewinding/loading/unloading a cartridge
5. Drive — amber
Off: no fault has been detected
Flashing: the drive mechanism has detected a hardware
error
6. Tape — amber
Off: no fault has been detected
Flashing: the cartridge currently in the drive is faulty
(damaged or unsupported). Discard the cartridge.
7. Clean — amber
On: cleaning cartridge in use
Off: the drive does not require cleaning
Flashing: the drive needs cleaning
8. Encryption — blue/amber
On (blue or amber): at power on
Off: drive is idle with no encryption key
Off with Ready LED flashing: drive is reading/writing
unencrypted data or loading/unloading a cartridge
On (blue): drive is idle with encryption key
On (blue) with Ready LED flashing: drive is reading/writing
encrypted data and some or all of the data on the cartridge
is encrypted
Blue and amber flashing alternately: encryption or
decryption error
Only the Ultrium LTO-5 and LTO-6 tape drives have
NOTE:
an encryption LED.
Using hardware encryption
Encryption protects data from unauthorized access
and use by changing it into a form that cannot be
read until it is deciphered with the encryption key.
LTO-4 and later generation tape drives include
hardware capable of encrypting data while writing,
and decrypting data when reading. Hardware
encryption can be used with or without compression
while maintaining the full speed and capacity of the
tape drive and media.
LTO tape drives use the 256-bit version of the
industry-standard AES encryption algorithm to
protect data.
IMPORTANT:
powerful feature and should be used with
care. If you need to import media onto
another machine or to recover after disaster
you will be required to enter the encryption
key used to write the tape. Neither you nor a
service engineer can recover a lost
encryption key. Without the key, an encrypted
tape is unreadable.
To use hardware encryption you need:
A backup application that supports hardware
encryption.
LTO-4 or later generation data cartridges; no
encryption will be performed when writing
LTO-3 and earlier generations of tape.
For additional information and requirements for
using hardware encryption, see the user guide.
