Select the security level of the key group.
"Security Level" indicates the handling level when application of the SED key to the
target RAID group fails. If the key for the relevant RAID group cannot be obtained from
the key server due to a communication error and the SEDs that configure the RAID group
are changed to hot spares or changed to new SEDs due to failure or maintenance, the
ETERNUS DX performs operations according to the selected security level.
Even if the security level is changed from "High" to "Low", the rebuilding process does not
start immediately after the level is changed. Rebuilding processes start after the
ETERNUS DX recognizes that changing of the security level and key is complete.
•
High
Rebuilding to hot spares for which the key cannot be changed after SED failure is not
performed. The RAID group loses its redundancy ("
Exposed" (only for High Reliability (RAID6)), "
ability (RAID6-FR)), or "
FR))).
When SED maintenance is being performed, replacing a SED with a new SED for
which the key cannot be changed does not complete successfully. If this action is
performed, the status of the new SED changes to "
When communication between the key server and the ETERNUS DX returns to normal
and the key can be obtained, the SED status changes to normal. Rebuilding to the
SED for which the status changed to normal is performed after the key is changed.
Note that "Modifying" may be displayed for the key status for few minutes even
though the SED key has already changed. After changing the key, maintenance of
the SEDs is complete.
•
Low
Rebuilding or maintenance is performed by using the common key if changing of the
key in the key server fails due to a network error.
Select the recovery mode of the key group.
The recovery mode is a method to recover locked (*1) RAID groups or SEDs after
communication with the key server is resolved. For RAID groups in locked status, "
Locked" is displayed. For SEDs in locked status, "
*1: A blocked status that occurs when the key of the RAID groups cannot be obtained.
•
Automatic
This mode recovers locked RAID groups or SEDs when the communication error with
the key server is resolved.
•
Manual
Use the [Recovery SED] function of ETERNUS Web GUI to recover the locked RAID
groups or SEDs when the communication error with the key server is resolved.
