•
If a LAN connection cannot be secured during SED authentication, authentication fails because the authen-
tication 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.
•
To use the authentication key in a key server, a key group needs to be created. Multiple RAID groups can be
registered in a key group. Note that only one key group can be created in each
ETERNUS AF. One authenti-
cation key can be specified for each key group. The authentication key for a key group can be changed.
•
Setting a period of time for the validity of the authentication key in the key server by using the ETERNUS AF
enables the key to be automatically updated by obtaining a new key from the key server before the validity
of the key expires. Access from the host (server) can be maintained even if the SED authentication key is
changed during operation.
•
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 manage-
ment 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 copy back (when using Global Hot Spares)
-
Performing a redundant copy (when using Global Hot Spares)
