2 Installation and configuration
Prepare the tape library and environment
Required configurations:
•
The tape library must be one of the supported HP tape libraries listed in the HP Linear Tape
File System (LTFS) Tape Drive and HP StoreOpen Automation Support Matrix on
•
The library or partition must have up to four HP LTO-5 or LTO-6 tape drives.
NOTE:
HP StoreOpen Automation must have connectivity to all of the tape drives and robotics
in the library or partition.
•
The library or partition can support up to 48 slots and 4 drives. See the library's user guide
for instructions on partitioning the library.
•
Only LTO-5 and LTO-6 media are supported by LTFS solutions.
•
Enable the library’s encryption features, if you want the LTFS tapes to be encrypted.
IMPORTANT:
To support auditing, HP tape libraries that are configured for encryption will
not allow mixing tapes with encrypted and clear text in the same partition. Therefore, when
enabling encryption, be sure the library or partition has new media, or media that can be
overwritten (and encrypted) from the beginning of each tape. The library will not allow
appending encrypted data to a tape cartridge that already contains clear text.
IMPORTANT:
Encryption is a feature of the tape library, and is not a feature of your LTFS
software, including HP StoreOpen Automation. Any tapes that are encrypted by the tape
library can only be decrypted by the same, or a different, HP library that is authorized to
access the same encryption keys that encrypted the data. See your tape library user guide for
more information on the library's encryption features.
•
Ensure the library or partition is only accessible from a single host. The following methods are
effective for ensuring a single host has access to the tape library or partition:
◦
Direct connect Fibre Channel or SAS connections
◦
HP's Secure Manager feature (available on EML and ESL series tape libraries)
◦
Zoned Fibre Channel fabric (switch zoning)
•
Ensure only one user or application on the host computer has access to the tape library. For
example, do not share the same library or partition with a backup application. If the host
system also runs a backup application, partition the library so the backup application and
the HP StoreOpen Automation user are accessing two separate partitions, with two separate
sets of tapes. All tapes in the library must have barcodes. See
StoreOpen Automation (page 13)
for more information on the required barcode format.
Recommended configurations:
•
The tape library should contain only LTO-5 or LTO-6 media. Other media generations are
tolerated, but will result in error conditions that impact the system performance.
•
The tape library or partition should contain only LTO-5 or LTO-6 drives. Other drive generations
are tolerated, but will result in error conditions that impact the system performance.
