HP StoreEver MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries User and Service Guide (AK378-96059, December 2012)

IMPORTANT: Misusing and misunderstanding bar code technology can result in backup and
restore failures. To ensure that your bar code labels meet HP's quality standards, always purchase
them from an approved supplier and never print bar code labels yourself.
To order bar code labels from an HP-authorized reseller:
• In the United States, call 1-800-345-1518.
• Elsewhere, see the HP website: www.hp.com, then click Contact HP to find locations and
telephone numbers.
For more information, see the Bar Code Label Requirements, Compatibility and Usage white paper
available from www.hp.com/support.
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:
Figure 50 Apply the label within the recessed area
IMPORTANT: The bar code label should only be applied as shown, with the alphanumeric 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.
Write-protecting tape cartridges
All rewriteable data cartridges have a write-protect switch to prevent accidental erasure or
overwriting of data. Before loading a cartridge into the device, make sure the write-protect switch
on the front of the cartridge is in the desired position.
• Slide the switch to the left to allow the device to write data to the cartridge (see
“Write-protecting the data cartridge” (page 60), 1).
• Slide the switch to the right to write-protect the cartridge. An indicator, such as a red mark or
small padlock, is visible showing that the cartridge is write-protected (see “Write-protecting
the data cartridge” (page 60), 2).
