在替換開機媒體上還原加密。

您必須使用開機媒體取代程序開始時所擷取的設定、完成特定於已啟用內建金鑰管理程式（ OKM ）、 NetApp 儲存加密（ NSE ）或 NetApp 磁碟區加密（ NVE ）的系統的步驟。

根據系統上設定的金鑰管理程式、請從開機功能表中選取下列其中一個選項以還原。

選項 1 ：還原 Onboard Key Manager 組態

從 ONTAP 開機功能表還原內建金鑰管理程式（ OKM ）組態。

開始之前
步驟

  1. 將主控台纜線連接至目標控制器。

  2. 從 ONTAP 開機功能表中、從開機功能表中選取適當的選項。

    版本ONTAP 選取此選項

    部分9.8或更新版本ONTAP

    選擇選項 10 。
