Starting a Tape Drive
The “START TAPE Command” (page 276) makes a tape drive accessible to user requests.
Considerations for START TAPE
• To start a tape drive, the tape drive must be connected to the external port of the adapter and
the tape drive must be powered on.
• If the tape process does not start, reset it with the FORCED option; then start it again.

Managing Encrypted Tape Drives
SCF supports encryption of data-at-rest for LTO-4 and LTO-5 tape objects that are connected with
CLIMs. Encryption uses keys generated and stored by the HP Enterprise Secure Key Manager
(ESKM). Customers use the ALTER and STATUS commands to manage encryption on tapes.
Only members of the SAFEGUARD encryption officer group on the local system can perform ALTER
TAPE with the NEWENCRYPTKEY or KEYGENPOLICY attributes. Encryption officers must also be
members of the Guardian SUPER.* group. Keys and system security should be managed by customer
security officers, not system administrators.
For details about encryption, see the NonStop Volume Level Encryption Guide.
