Control Path Modification
1
The control path tape drive is used to connect a partition to a host
application. Only one tape drive can be selected as the control path at one
time. By default, the first tape drive assigned to a partition is designated
the control path. In the event that the control path connection to the host
application fails, you can select a new control path for the partition.
Support for WORM
1
Scalar i500 tape libraries support WORM (write once, read many)
technology in LTO-3 and LTO-4 tape drives. WORM allows non-
rewriteable and non-erasable data to be written and provides extra data
security by prohibiting accidental data erasure. The WORM feature is
supported whenever you use WORM cartridges.
Licensable Features
In addition to the standard features, the following additional, licensable
features are available for the Scalar i500:
•

•
Quantum Encryption Key Manager (Q-EKM)

If you purchase these features with your library, they will be installed
when you receive the library. If you upgrade or add new features after
the initial purchase, you will need to obtain and install a license key. For
information on how to obtain and install a license key, see

Control paths are not used in partitions that contain FC tape
drives connected to host applications through FC I/O blades.
