Last updated at Posted at 2025-12-17

はじめに

NIMマスターを用いて、NIMクライアントのシステム・バックアップを作成した際の作業メモです。

実施環境

  • NIMマスター
    • ホスト名:s922211
    • OS:AIX 7.3 TL3 SP0
    • IPアドレス:192.168.64.11
  • NIMクライアント (バックアップ取得対象)
    • ホスト名:s922203
    • OS:AIX 7.3 TL3 SP0
    • IPアドレス:192.168.64.3

実施内容

NIMを用いたAIX導入手順と同様の手順で、NIMマスターにバックアップ取得対象のNIMクライアント(s922203)を登録しました。

登録後、NIMマスターでシステム・バックアップ(mksysb)を作成しました。
