You can remove a key management server linked to the storage system by using the key_manager remove command.
Storage Encryption requires at least one key management server linked to the storage appliance to operate. If you want to replace a single key management server with another one, first add the new one before removing the old one.
You must know the IP address for each key management server you want to remove.
-key_server key_server_ip_address specifies the IP address of the key management server you want to remove.
The following command removes the link between the storage system and the key management server with the IP address 172.18.99.175:
storage-system> key_manager remove -key_server 172.18.99.175 Key server 172.18.99.175 will be unregistered from service. Unregistration successful.
