Chapter 2 Using Automated Libraries and Manually Loaded Drives 31

Using Drives With Encryption Capability

If you are archiving files to drives with encryption capability, there are some special

considerations:

■ You should not mix non-encrypted and encryption-capable drives in a library.

■ Once a drive has encryption enabled, it cannot be disabled.

■ You cannot mix encrypted and non-encrypted files on a tape.

■ An encrypted drive cannot append to a tape that contains non-encrypted data.

■ An encryption-enabled drive can, however, read non-encrypted data.

Given these limitations, you must carefully plan archive sets and tape assignments

in the archiver.cmd file if you are using both non-encrypted and encrypted data

and drives in your archiving system.

Manually Loaded Drive Operations

This section describes operations that differ if you have a manually loaded, stand-

alone drive rather than an automated library. Each manually loaded drive has its

own one-slot library catalog.

▼ To Load a Cartridge

● To load a cartridge into a manually loaded device, place the cartridge in the drive

according to the manufacturer’s instructions.

The Sun StorageTek SAM system recognizes that the cartridge is loaded, reads the

label, and updates the one-slot catalog. No further action is necessary.
