Users Guide
• Basic Function - To initiate use of cartridges, the user issues a Move Cartridge command to the drive
through the Management GUI. After the load, the host application can begin data I/O activity. When the
host application unloads the drive, the library moves the next cartridge into the drive. This behavior is
implicit, unless otherwise dened by selection of another option.
• Loop Option - If a move sequence ends because no more cartridges are available in the current logical
library, the sequence starts again by loading the rst cartridge of the logical library. This option can be
chosen with or without the Autoload function.
• Autoload Option - If enabled, the library loads the rst cartridge of the logical library to the Sequential
Mode tape drive during library startup after inventory scan is nished. This option changes the implicit
behavior of the Basic function. This option can be chosen with or without the Loop option.
If storage slots are congured to I/O slots after assignment to a Sequential Mode logical library, they are
still considered valid available slots and are used for movements. This option stays until you run the
expert wizard again, and then these I/O slots no longer appear in the list of available slots. Finishing the
expert wizard then sets the new slot assignment and these I/O slots can no longer be used for
movements.
To enable sequential mode, click the Enable Sequential Mode check box in the Basic Logical Library
Wizard or Expert Logical Library Wizard.
Encryption
All supported tape drives in this library support encryption.
The encryption enabled drive contains the necessary hardware and rmware to encrypt and decrypt host
tape application data. Encryption policy and encryption keys are provided by the host application or host
server. A drive digital certicate is installed at manufacturing time. Each drive receives a unique serial
number and certicate. The T10 application might validate each drive instance by checking the drive's
digital certicate.
The library provides these options.
1. Encryption disabled
2. Application Managed Encryption (AME)
3. Library Managed Encryption (LME). LME is a built-in feature. For conguration details, see
“Conguring Library Managed Encryption” on page 72
.
The default is Application Managed Encryption.
Enabling library-managed encryption on a Dell EMC ML3 is a six-step process.
1. Upgrade the library and drive rmware to the current versions. The rmware can be found at
www.Dell.com/support.
2. Library-managed encryption on the library is already activated and cannot be deactivated.
If issues occur with the library-managed encryption on the library, go to http://www.dell.com/
tapeautomation for information on resolving the issue. If your issue is not resolved, contact Dell
technical support.
3. Congure library-managed encryption on your library.
4. Install the IBM SKLM application on the server that is designated as the key manager. See IBM SKLM
Knowledge Center for information.
5. Congure the IBM SKLM application. See IBM SKLM Knowledge Center for information.
6. Start the IBM SKLM application. See IBM SKLM Knowledge Center for information.
Note: All encryption settings must be congured or reveried in the drive after any library or drive reset. A
new drive might be added or an existing drive might be swapped with another drive.
