cartridge quickly, thereby speeding up inventory time. Make it a practice to use bar code labels
on your tape cartridges.
TIP: The bar code scanner must scan each tape or the back of the storage slot until it reads
the bar code label for the cartridge or storage slot, or determines that the slot is empty. The bar
code scanner can identify a properly labeled cartridge on the first scan. It can identify an empty
slot on the second scan. It will try several more scans and then tap on the cartridge before
determining that an unlabeled cartridge is in the slot, which takes about four times as long as
identifying a properly labeled cartridge. The inventory time for an MSL8048 or MSL8096 filled
with unlabeled cartridges is about 30 minutes. Even if you do not need the bar code information,
use bar code labels to speed up inventory time.
A proper bar code label includes the Media ID in the last two characters of the bar code. LTO-3
and earlier generation tape drives prevent later generation media from being loaded into the
drive. If an LTO-4, LTO-5, LTO-6, or LTO-7 tape drive is installed in the library or is in the removed
state, the library will not load an unlabeled cartridge into an LTO-3 or earlier generation tape
drive.
Though not recommended, checking Ignore Barcode Media ID in the RMI Configuration >
System screen will keep the tape library from interpreting bar code Media IDs.
The host software might track the following information via the associated bar code:
Date of format or initialization
Tape's media pool
Data residing on the tape
Age of the backup
Errors encountered while using the tape (to determine if the tape is faulty)
IMPORTANT:
restore failures. To ensure that your bar code labels meet Hewlett Packard Enterprise's quality
standards, always purchase them from an approved supplier and never print bar code labels
yourself. To purchase bar code labels, see the Hewlett Packard Enterprise Storage Media website

paper available from http://www.hpe.com/support/storage.
LTO tape cartridges have a recessed area located on the face of the cartridge next to the
write-protect switch. Use this area for attaching the adhesive-backed bar code label. Only apply
labels as shown:

IMPORTANT:
portion facing the hub side of the tape cartridge. Never apply multiple labels onto a cartridge
because extra labels can cause the cartridge to jam in a tape drive.
