2. Basic Functions
Data Encryption
Caution
If a LAN connection cannot be secured during SED authentication, authentication fails because the
authentication key that is managed by the key server cannot be obtained.
To use the key server linkage function, a continuous connection to the LAN must be secured.
Note
When linking with the key management server, the ETERNUS AF obtains the SED authentication key from
the key server and performs authentication when key management settings are performed, key
management information is displayed, and any of the following operations are performed.
• Turning on the ETERNUS AF
• Expanding the RAID group capacity (Logical Device Expansion)
• Forcibly enabling a RAID group
• Creating the key group
• Recovering SEDs
• Performing maintenance of drive enclosures
• Applying disk firmware
• Registering Dedicated Hot Spares
• Rebuilding and performing copyback (when using Global Hot Spares)
• Performing a redundant copy (when using Global Hot Spares)
