3ware97504i-再起動時にディスクマッピング/ UUIDが変更される

Question

36台のドライブを実行している3ware9750-4iがあります（RAID 10では4台、残りは個々のドライブ、つまりJBOD）。

再起動すると、RAID 10アレイを除くすべてのドライブのUUIDが再起動時に変更されます（何度か再起動したため、毎回完全に異なるUUIDであったため、ランダムに見えます）。これにより、手動で32台のドライブを調べ、実際にマッピングする場所を見つけて、そこに再マウントします。

この問題に関連するものもオンラインで見つかりませんでした。私は一般的にRAIDカードを初めて使用します。私が見逃しているかもしれないある種の設定はありますか？あるいは、私のカーネルに何かが原因でこれを引き起こしているかもしれません（繰り返しますが、私はカーネルについてもあまり知識がありません）

編集：Debian 7.664ビットを実行しています。

すべて同じであるため、出力を最初の数台のドライブのみに制限していることに注意してください。

この問題の回避策として、名前の代わりにLVM /ラベルを使用してドライブをマウントできます。これは元の問題の解決策ではありませんが、これによって結果が解消されることを願っています。
