Quantum P4000 and P7000 Libraries User’s Guide
When fewer than 8 drives are installed in a P4000 or fewer than 16 tape
drives are installed in a P7000, the tape drives must occupy consecutive
drive bays, beginning with drive bay 0.
The drives used in both the P4000 and P7000 are more reliable than
standard drives due to the automated environment.
Both the P4000 and P7000 can be populated simultaneously with DLT,
SDLT, or LTO tape drives.
If a drive experiences read/write errors when the AutoClean function is
enabled, the library issues an error message stating that drive cleaning is
required. Without user intervention, the IntelliGrip CHM replaces the
data cartridge with a cleaning cartridge. When the cleaning procedure
finishes, the CHM returns the data cartridge to the drive.
Load Port and
Magazines
1
The load port is a mechanical device in the front panel of the library that
enables you to import or export tape cartridges to and from the library
via two tape cartridge magazines without interrupting library operations.
The DLT/SDLT load port uses two removable 6-bin tape cartridge
magazines (see
).
The LTO load port uses two stationary 4-bin tape cartridge magazines
).
Note:
When a DLT cleaning cartridge has completed its 20-use limit,
it is automatically exported from the library, requiring a new
one to be loaded through the load port.
