1. Note which character is displayed in the SCD. Refer to the
appropriate action for the error indicated.
2. Confirm that your drive is operating with latest-level firmware. Download new firmware from the IBM website, if needed.
3. Perform the Drive SELF-TEST Procedure (see
the performance of your LTO-7 tape drive, without impacting server operation.
The Fault LED is On Solid
The solid Fault LED indicates that the tape drive maximum operating temperature has been exceeded. To protect your media,
the drive automatically ejects the current tape cartridge, and the drive must cool down before operation can resume.
Wait for the tape drive to cool down and for the Fault LED to turn off. After the tape drive cools down, you can load a tape
cartridge and restart your backup or restore job. Confirm that the IBM server is in a cool, well-ventilated environment.
Tape Drive Does Not Accept a Cartridge
If the tape drive does not accept a cartridge, complete the following steps:
1. Verify that the tape drive is not indicating an error state. If a character is displayed on the SCD, refer to
Messages and take appropriate action for the error indicated.
2. Inspect your tape cartridge. Verify that it is not damaged, and the leader pin is correctly positioned inside the cartridge
door. If needed, refer to the following URL for tips on inspecting LTO tape cartridges:

3. Verify that you are attempting to load a compatible cartridge type. LTO-7 drives are write-compatible with Ultrium5,
Ultrium6, and Ultrium7 media only. Other cartridge types automatically ejected by the drive, if a write operation is
attempted.
4. Verify that another cartridge is not already loaded in the drive. Press the eject button, if needed.
The Host System Backup Application is Reporting an Error
The host system backup application may report an error as a result of a failure by the tape drive to write or read data. If your
backup application reports a media error, complete the following steps:
1. Clean the drive (see
2. Verify that the data cartridge you are using for your backup job is a good one.
Note: The Drive SELF-TEST Procedure can also be used to check the integrity of your media.
3. Try using another LTO data cartridge for your backup job. Mark any cartridge that fails. If you notice that the same
cartridge is involved in multiple failures, it may be time to replace that cartridge. In some cases, media suppliers will
replace a defective cartridge at no cost.
4. If you are trying to backup (write) data, verify that your cartridge is not write-protected. Check the red write-protect
switch on the edge of the cartridge, and confirm that it is in the unlocked position (see
Using LTO Ultrium Media
Use only IBM LTO Ultrium tape cartridges in the LTO tape drive. You may use other LTO-certified data cartridges, but they may
not meet the standards of reliability that are established by IBM. The IBM LTO Ultrium Data Cartridges cannot be interchanged
with the media used in other IBM non-LTO Ultrium tape products.
