Drive ADI Interface

Oracle’s StorageTek modular libraries support LTO (Linear Tape Open) drives from HP and IBM. For a library to send rich LTO drive data to STA, ADI (Automation/Drive Interface) must be enabled on both the library and the LTO drives. If ADI is not enabled on both, the library will only send minimal data about the LTO drives.

Enabling ADI on the Drives

The ADI interface is available on the following drive models:

Note – For all HP LTO drives, after you enable ADI mode in the library, the drive auto-switches to ADI mode on next initialization (library reboot).

Note – The Belisarius card provides the interface between the drive and Oracle’s Key Manager (OKM) tape encryption solution.

Note – If ADI has been enabled on IBM LTO drives, the drives will not be recognized unless 1) ADI has also been enabled on the library, and 2) the library has been rebooted after enabling ADI on the library. See “Enabling ADI on the Library”.

Note – See the “Tape Drive Requirements” section within the STA Planning and Installation Guide for LTO drive support information.

The method for enabling ADI on the drives depends on the drive model and manufacturer. See TABLE 1‑2 for details.

TABLE 1‑2 How ADI is Enabled on LTO Drives

Manufacturer/Model	LTO‑3	LTO‑4	LTO‑5, LTO-6
HP	Auto-enabled	Auto-enabled	Auto-enabled
IBM without the Belisarius adapter card	An Oracle support representative must configure the drive hardware for ADI mode.	An Oracle support representative must configure the drive hardware for ADI mode.	Not available
IBM with the Belisarius adapter card1	Not available	An Oracle support representative must configure the drive hardware for ADI mode. Drive and Belisarius card firmware must also meet minimum requirements for STA.	The drive firmware must be configured for ADI mode.2 Drive and Belisarius card firmware must also meet minimum requirements for STA.

See the STA Planning and Installation Guide for firmware requirements for IBM LTO-4, LTO-5, and LTO-6 drives with the Belisarius adapter card.

This is performed with Virtual Operator Panel (VOP). Contact Oracle support for assistance.

Enabling ADI on the Library

By default, ADI is not enabled on SL500, SL3000, and SL8500 libraries, and you or your Oracle support representative must enable ADI manually. Because enabling ADI requires a reboot of the library, it is recommended that you enable ADI now if you plan to include LTO drives in the library in the near future.

Note – ADI is enabled by default on the SL150 library.

See “Enable ADI on the Library” for instructions on checking the library ADI status and enabling ADI.

For SL3000 and SL8500 libraries, ADI can be enabled only if the library has a high-memory drive controller (HBT) card. If the library has a low-memory HBT card, the ADI interface will not enable successfully. See “Verify the Drive Controller Card Version” for instructions.
