この問題は、両方のサーバーに影響を及ぼします。
IPoIB を使用してアクセスされる iSCSI デバイスにルートファイルシステムを保存して Oracle Solaris をインストールしたあとに、続けて Oracle Solaris をほかのストレージデバイスに再インストールした場合、新しくインストールされた OS インスタンスをブートすると、以前にインストールされた iSCSI デバイスからルートファイルシステムをマウントしようとします。この状況は、os-root-device NVRAM 変数が引き続き存在することが原因です。次に例を示します。

回避方法: 次の手順を実行して、os-root-device 変数をクリアします。
ok プロンプトで os-root-device をクリアします。
ok set-default os-root-device
OS をブートします。
ok boot
