Key Group
Overview
This function displays the SED authentication key (hereinafter, referred to as "key") information that is used for a key group and the SSL/KMIP certificate information.
The key group combines all of the RAID groups that use the same key.
The RAID groups that are registered in the key group can be checked by using the [SED Key Group] screen. Refer to the [SED Key Group] function for details.

Key Group
Item | Description | ||||
---|---|---|---|---|---|
Name |
The key group name is displayed. If no key groups are created, the field is blank. The key group name corresponds to "Serial Number", which is managed in the key server. |
||||
Storage System Group Name |
The storage system group name is displayed. If no key groups are created, the field is blank. The storage system group combines the key management device (Key Management Machine) name that is managed by the user with the key group. The storage system group name corresponds to "Device Group Name", which is managed in the key server. Note that "ETERNUS_DX" is specified as the factory default storage system group name when "ETERNUS SF KM" (key management software) is shipped. |
||||
Key Status |
The key status is displayed. If no key groups are created, the field is blank. Refer to "Key Status" for details. |
||||
Security Level |
The security level for the key group is displayed. If no key groups are created, the field is blank. "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 storage system 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 storage system recognizes that changing of the security level and key is complete. |
||||
Recovery Mode |
The recovery mode for the key group is displayed. If no key groups are created, the field is blank. 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, "SED Locked" is displayed. For SEDs in locked status, "Not Exist" is displayed.
|
||||
Key Expiration Date |
The following information is displayed depending on the key status.
If no key groups are created, the field is blank. When the key has expired, a new key is obtained from the key server and automatically applied in place of the expired key. |
