Set Key Group (RAID Group)

Overview

This function adds or deletes RAID groups that are configured by SEDs in the key group.

RAID groups in the key group are managed by the SED authentication key that is obtained from the key server. One key group can be created in the storage system.

If a RAID group is not registered in the key group, the RAID group is managed by the common key.

Caution
  • When registering RAID groups in the key group, perform the following settings in advance.

    1. Create a key group.

    2. Allocate the master server or the slave server to the key group.

    3. Set the key for the key group and confirm that the key status is "Normal".

    Refer to the [Create Key Group] function and the [Update SED Authentication Key] function for details.

  • RAID groups with a status other than "Available" cannot be added to the key group.

Note

  • Information on the RAID groups that are configured by SEDs and registration status to the key group can be checked in the [SED Key Group] screen. Refer to the [SED Key Group] function for details.

  • Use the [Key Group] screen to check the SED authentication key information and the SSL/KMIP certificate information that is used for the key group. Refer to the [Key Group] function for details.

  • Even when volumes that belong to the key management target RAID group are being used, RAID groups can be added to or deleted from the key group.
