When you want to manage the storage system by using Hitachi Command Suite and perform the HCS external authentication, you need to register the certificate for HCS on the SVP.
When you want to manage the storage system by linking Hitachi Ops Center Administrator and Hitachi Device Manager - Storage Navigator (HDvM - SN), you need to register the certificate for Hitachi Ops Center Administrator on the SVP.
You cannot register the certificate for both of the HCS and Hitachi Ops Center Administrator at the same time. Register one of the certificate for the server you are using to manage the storage system.
