Nutanix CE 上の Prism Central が起動できなくなってしまったので、下記の KB を参考に、強制的に Prism Element から削除してみます。
※ただし、本番環境の Nutanix では気軽に実施せず、ちゃんと製品サポートに問い合わせしたうえで作業を開始するとよいかなと思います。
それでは、CVM に SSH でログインして作業します。まず、ncli コマンドで Prism Central の Cluster ID を確認します。
nutanix@NTNX-7e2b5cd3-A-CVM:192.168.20.52:~$ ncli multicluster get-cluster-state
Registered Cluster Count: 1
Cluster Id : 47603a98-c888-4f6a-a7b6-86210c312ad1

ncli コマンドで、Prism Central の Cluster ID を指定して登録を削除します。
nutanix@NTNX-7e2b5cd3-A-CVM:192.168.20.52:~$ ncli multicluster delete-cluster-state cluster-id=47603a98-c888-4f6a-a7b6-86210c312ad1 Cluster state deleted successfully
Prism Central の登録が解除されました・・・
一応、クリーンアップ スクリプトを実行しておきます。
