使用 CloudLink 將 PowerFlex 4.x 作業系統更換至 SUSE 的 CentOS 失敗
摘要: 執行從 CentOS 到 SLES 的作業系統遷移時，當已安裝 CloudLink （clc-agent） 時，會失敗且無法重試，因為「取代」標籤將會停用。

在安裝了已加密所有磁碟的 CloudLink 的系統上，OS 從 CentOS 遷移至 SLES 失敗。
原因
若要成功更換使用 CloudLink 之系統的作業系統，PFMP 要求 CloudLink 相容。確認相容性後，PFMP 會中斷 CLC 代理程式與 CentOS 的連線，並將其安裝在 SLES 上。連線至 CloudLink 伺服器並交換金鑰後，裝置即可成功解除鎖定磁碟機，確保使用 CloudLink 順利遷移。
在 CloudLink 處於不相容狀態時執行作業系統更換時，系統會忽略 CloudLink 遷移，這與在沒有 CloudLink 的系統上更換標準作業系統類似。 PFMP 不會中斷 CentOS 上的 clc 代理程式，也不會安裝在 SLES 上，導致裝置進入錯誤狀態。
解析度
|
若要在新安裝的 SLES 節點上安裝 CloudLink，請使用下列步驟：
請在執行命令前先變更 IP。
注意 -G 代表群組 ID。 群組 ID」是雲端連結中群組的註冊代碼，如螢幕擷取畫面所示。 如果未提供組 ID，則會將電腦添加到預設組中。
如果裝置是手動移除的，請加回。 |
