IP over InfiniBand (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が格納されているサーバーに Oracle Solaris をインストールしたあとで、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すると、新しくインストールされた Oracle Solaris インスタンスのブートで、IPoIB を使用して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。例:

回避方法:
ok プロンプトで os-root-device をクリアします。
ok set-default os-root-device
Oracle Solaris をブートします。
ok boot
